    Seattle and San Francisco

  4. DOption (d)

    Seattle and Osaka 

View answer & explanation

Correct answer

Answer: (c)C.

Seattle and San Francisco

Why this answer is correct

Correct Answer: Seattle and San Francisco

Key Points 

  • Silicon Forest is a nickname for the cluster of high-tech companies located in the Portland metropolitan area, which is near Seattle in the broader regional sense,
  • although Portland and Seattle are distinct cities in the Pacific Northwest of the United States.
  • Silicon Forest refers to the industrial corridor between Beaverton and Hillsboro in northwest Oregon and is closely associated with the Portland area, not directly Seattle.
  • Silicon Valley is globally recognized as a major center for high technology, innovation, and social media.
  • It is located in the southern part of the San Francisco Bay Area in Northern California, making San Francisco the nearest major city to this technopolis.
  • The region corresponds roughly to the geographical area of Santa Clara Valley and is home to many of the world's largest high-tech corporations as well as thousands of startup companies

Question 2

In 2021, which country was the leading steel producer and exporter of the world? 

  1. AOption (a)

    Japan

  2. BOption (b)

    China

  3. COption (c)

    USA

  4. DOption (d)

    Australia

View answer & explanation

Correct answer

Answer: (b)B.

China

Why this answer is correct

China

 Key Points

  • China was the leading steel producer and exporter in the world in 2021.
  • It has been at the forefront of steel production for several years, contributing significantly to the global steel supply.
  • China's steel industry is massive, with numerous large-scale steel mills and a substantial domestic and international market.
<br>

 Additional InformationJapan, while a major player in the steel industry, was not the leading steel producer and exporter in 2021. Japan has a highly developed steel industry and is known for its advanced technology and quality steel products, but its production volume is significantly less than China's.

<br>

USA is another significant steel producer globally, with a long history of steel production contributing to its industrial and economic development. However, the United States also did not lead in steel production and export in 2021 compared to China. The U.S. steel industry has faced challenges such as global competition and tariffs, impacting its global standing.

<br>

Australia is known for its vast reserves of raw materials like iron ore, which are crucial for steelmaking. While Australia is a major exporter of iron ore, it is not a leading producer and exporter of finished steel products. The Australian steel industry focuses more on domestic demand and specific international markets but does not match China's production and export volumes.

<br>

In summary, China's dominant position in the global steel industry, backed by its massive production capacity, extensive infrastructure, and strategic government policies, places it at the top as the leading steel producer and exporter in 2021. Other countries like Japan, the USA, and Australia have significant steel industries but did not surpass China in terms of production and export volumes during that year.

Question 3

Identify the World's leading country in the exports and imports of commercial services in 2021 as per World Trade Organisation (WTO) report.  

  1. AOption (a)

    USA

  2. BOption (b)

    India

  3. COption (c)

    China

  4. DOption (d)

    Japan

View answer & explanation

Correct answer

Answer: (a)A.

USA

Why this answer is correct

USA:

Key Points 

  • Leads the world in both the exports and imports of commercial services as of 2021, according to the World Trade Organization (WTO) report.
  • Has a highly diversified service sector, including finance, technology, and intellectual property, which contributes significantly to its export figures.
  • Its position as a global financial hub and the presence of tech giants contribute to its top ranking in service exports and imports.

Additional Information 

India:

  • Known for its IT and software services, making it a significant player in the global services export market.
  • However, it does not surpass the USA in the total value of exports and imports of commercial services.
<br>

China:

  • Dominates in goods manufacturing and exports but is also rapidly growing its services sector.
  • Despite substantial growth in services like tourism and technology, it still trails behind the USA in the total services trade.
<br>

Japan:

  • A leading global economy with strong exports in technology and automotive sectors.
  • Its service sector is robust, with significant contributions from finance, insurance, and entertainment, but does not lead the world in service exports and imports.
<br>

Conclusion:

  • While India, China, and Japan are significant players in the global market for various services, the USA holds the leading position in the exports and imports of commercial services as of 2021.
  • This is attributed to its diversified and vast service sector, ranging from technology and finance to intellectual property, positioning it at the forefront of the global services trade.

Question 4

Which one of the following highlighted that "An area is poor because it is poor"? 

  1. AOption (a)

    Gunnar Myrdal's cumulative causation 

  2. BOption (b)

    Perroux’s growth pole  

  3. COption (c)

    Meadow's limits to growth 

  4. DOption (d)

    Rostow's stages of Economic Growth 

View answer & explanation

Correct answer

Answer: (a)A.

Gunnar Myrdal's cumulative causation 

Why this answer is correct

Gunnar Myrdal's cumulative causation:

Key Points

  • Myrdal introduced the concept of cumulative causation, which highlights how positive or negative economic forces in a region can reinforce themselves, leading to a cycle of prosperity or poverty.
  • The statement "An area is poor because it is poor" encapsulates this idea, suggesting that poverty leads to conditions that perpetuate poverty, such as lack of investment, poor infrastructure, and limited access to education and healthcare.

Additional Information 

Perroux  growth pole: This theory focuses on the idea that economic development is not uniform across a region but rather concentrated around a few key industries or "growth poles" which then stimulate development in surrounding areas through various spillover effects. This concept does not directly address the self-reinforcing nature of poverty.

<br>

Meadows' limits to growth: This theory, originating from a 1972 report by the Club of Rome, suggests that exponential economic and population growth are unsustainable within the finite limits of Earth's resources. While it addresses global sustainability issues, it doesn't specifically explain the perpetuation of poverty within a region.

<br>

Rostow stages of Economic Growth: Rostow outlines a linear progression of economic development, from traditional societies to the age of high mass consumption. This model suggests that all countries can reach prosperity by following a similar path of industrialization and growth. It doesn't directly address why some areas remain poor due to internal dynamics of poverty.

<br>

In summary, Gunnar Myrdal's concept of cumulative causation directly addresses the self-reinforcing cycle of poverty in specific areas, making it the correct answer to the question. Other options, while important in the study of economic development, focus on different aspects of growth and do not encapsulate the idea that "An area is poor because it is poor" as Myrdal's theory does.

Question 5

Identify the city from the following where 27th meeting of the Conference of Parties (CoP-27) took place?

  1. AOption (a)

    Glasgow 

  2. BOption (b)

  3. COption (c)

    Madrid

  4. DOption (d)

    Bonn

View answer & explanation

Correct answer

Answer: (b)B.

Sharm EL-Sheikh 

Why this answer is correct

Correct Answer: Sharm EL-Sheikh

Key Points

  • The 27th meeting of the Conference of Parties (CoP-27) took place in Sharm EL-Sheikh, Egypt.
  • This international gathering is part of the United Nations Framework Convention on Climate Change (UNFCCC), where world leaders, negotiators, government representatives, businesses, and citizens come together to discuss and negotiate agreements to combat climate change.

Additional Information

  • Glasgow: Hosted the 26th meeting of the Conference of Parties (CoP-26) in 2021. It was a significant event where various countries updated their commitments to reduce carbon emissions and address climate change.
  • Madrid: Was the host city for the 25th meeting of the Conference of Parties (CoP-25) in 2019. The conference focused on finalizing the rules needed to implement the Paris Agreement fully.
  • Bonn: Regularly hosts interim climate change conferences and is home to the UNFCCC secretariat, but it did not host CoP-27. It plays a crucial role in the ongoing administrative and supportive tasks related to the UNFCCC process.

Important Points

  • COP 28 Summit 2023
  • Date and Location: November 30 – December 12, 2023, Expo City, Dubai, United Arab Emirates

Question 6

Which of the following is not one of the broad five socio-economic themes in Aspirational Districts Programme? 

  1. AOption (a)

    Health and Nutrition 

  2. BOption (b)

    Financial Inclusion and Skill Development 

  3. COption (c)

    Basic Infrastructure 

  4. DOption (d)

    Import Substitution and Export Promotion 

View answer & explanation

Correct answer

Answer: (d)D.

Import Substitution and Export Promotion 

Why this answer is correct

Import Substitution and Export Promotion 

Key Points

  • The Aspirational Districts Programme (ADP), launched by the Government of India, focuses on the rapid transformation of districts that are significantly lagging on key developmental parameters.
  • The primary focus of the ADP is on 'convergence' of government schemes, 'collaboration' among various stakeholders, and 'competition' among districts to improve their socio-economic status.
  • The program targets improvements in sectors critical to enhancing the quality of life and economic productivity of its citizens.
  • While import substitution and export promotion are important economic strategies, they are not directly listed as one of the broad socio-economic themes under this program.

Explanation of Incorrect Options:

Health and Nutrition: This is indeed one of the five core areas the ADP emphasizes. Efforts in this area aim to improve the overall health and nutritional status of the population in the targeted districts, addressing issues like child mortality, maternal health, and malnutrition.

Financial Inclusion and Skill Development: This theme focuses on increasing access to financial services and improving skill development among the population. The goal is to enable better economic opportunities and livelihoods for the people living in these districts, making it a critical component of the ADP.

Basic Infrastructure: The development of infrastructure such as roads, electricity, water supply, and Internet connectivity forms another key theme under this program. Improving basic infrastructure is vital for enhancing the quality of life and enabling economic activities in the aspirational districts.

Additional Information The other two themes under the Aspirational Districts Programme include 'Education' and 'Agriculture & Water Resources'. These five areas are critical for achieving sustainable development and improving the living conditions in the identified districts. The program uses a data-driven approach to identify areas of immediate improvement and to monitor the progress of these districts over time.

Why this answer is correct

Sweden:

 Key Points

  • Kiruna and Gallivare are located in the northern part of Sweden within the Arctic Circle.
  • These areas are renowned for their extensive magnetite ore mines, which are among the largest iron ore mines in the world.
  • Sweden's economy benefits significantly from the mining industry, with iron ore being a major export product.

 

Additional Information 

  • Australia:
  • Although Australia is a leading iron ore producer globally, with notable mines in regions like the Pilbara in Western Australia, it is not the correct answer in this context.
  • The mining industry in Australia primarily focuses on hematite and magnetite, but the specific locations mentioned (Kiruna and Gallivare) are not found here.
<br>
  • Brazil:
  • Brazil is another global leader in iron ore production, with the Carajas Mine being one of the worldundefineds largest.
  • However, Brazil is not associated with the Kiruna and Gallivare mines. These mines are not located in Brazil but in Sweden.
<br>
  • Canada:
  • Canada has a significant mining industry with various mineral resources, including iron ore.
  • Despite its vast mining operations, the specific mines of Kiruna and Gallivare are not situated in Canada, but in Sweden.

View answer & explanation

Correct answer

Answer: (b)B.

B - D - C - A

Why this answer is correct

B - D - C - A

Key Points

  • It's observed that Eastern Africa and Western Africa have higher rates of undernourishment due to various factors including economic instability, conflict, climate variability, and poor agricultural productivity.
  • Sub-Saharan Africa, a region encompassing both Eastern and Western Africa, also reports high levels of undernourishment collectively, although Sub-Saharan Africa as a designation might sometimes refer to a broader region beyond just these two sub-regions.
  • North Africa, while facing its own challenges, generally has a lower prevalence of undernourishment compared to regions south of the Sahara.
  • Eastern Africa (B): Typically reports the highest levels of PoU among these groups, due to factors like drought, conflict, and high population growth rates.
  • Sub-Saharan Africa (D): As a broader category encompassing both Eastern and Western Africa, it sees high levels of PoU; however, placing it here highlights that we're considering distinct sub-regions and their specific challenges too.
  • Western Africa (C): Also experiences high rates of undernourishment, affected by similar factors as Eastern Africa, though interventions and regional variations exist.
  • North Africa (A): Generally has lower levels of undernourishment compared to the Sub-Saharan regions, thanks to relatively better economic conditions and food security measures, despite facing its own set of issues.

A, B and C only  

Why this answer is correct

  • Correct Answer: A, B, and C only

Key Points 

  • Alfred Thayer Mahan was a United States Navy officer, geostrategist, and historian. His works have had a profound impact on naval strategy.
  • His most famous work, "The Influence of Sea Power upon History, 1660-1783," argued that naval supremacy was the key to global dominance.
  • It revolutionized naval strategy and profoundly influenced naval policies worldwide.
<br>

Additional Information 

A. The Influence of Sea Power upon History, 1660-1783 is indeed written by Alfred Thayer Mahan. It is his most famous work and outlines how countries with greater naval power had greater worldwide impact. It significantly influenced naval strategy across the world.

B. The Life of Nelson: The Embodiment of the Sea Power of Great Britain is another work by Mahan. It focuses on the life of Admiral Horatio Nelson and serves as a case study in the effectiveness of sea power.

C. The Influence of Sea Power upon the French Revolution and Empire, 1793-1812 is a continuation of Mahan's analysis on the impact of naval power, specifically looking at the French Revolutionary and Napoleonic Wars.

D. The Geographical Pivot of History is not written by Alfred Thayer Mahan but by Halford Mackinder. This work is a pivotal piece in the field of geopolitics and does not pertain to naval strategy

Question 10

Which of the following country is not considered as a Nation-State? 

  1. AOption (a)

    Belgium 

  2. BOption (b)

    Japan 

  3. COption (c)

    Egypt

  4. DOption (d)

    Sweden

View answer & explanation

Correct answer

Answer: (a)A.

Belgium 

Why this answer is correct

Belgium 

The concept of a nation-state is predicated on the notion that the state encompasses a single nation, characterized by a shared ethnicity, language, and culture. While many countries strive towards this ideal, the reality is often more complex due to historical, ethnic, and linguistic diversity. Belgium's situation exemplifies these complexities, distinguishing it from more homogeneous examples like Japan, Egypt, and Sweden.

 Key Points

  • Belgium is not considered a nation-state because it is a complex state composed of different linguistic and cultural groups, mainly the Flemish-speaking community in the north and the French-speaking community in the south.
  • This diversity challenges the concept of a nation-state, which is typically characterized by a relatively homogeneous cultural or ethnic group within its borders.
<br>

 Additional InformationJapan, on the other hand, is a classic example of a nation-state due to its ethnically homogeneous population. The vast majority of its inhabitants share a common language, culture, and history, making it a strong example of a nation-state.

<br>

Egypt is also considered a nation-state. It has a long and continuous history that dates back to one of the world's earliest civilizations. The majority of its population shares a common culture, language (Arabic), and identity, fitting the criteria of a nation-state.

<br>

Sweden is another example of a nation-state. It has a highly homogeneous society in terms of ethnicity, culture, and language. The Swedish people share a common history, traditions, and values, which aligns with the concept of a nation-state.

Question 11

The scientific observations about the size, shape and circumference of the earth were made by Eratosthenes and Hipparchus at which of the following place?  

  1. AOption (a)

    Tanais 

  2. BOption (b)

    Tyras

  3. COption (c)

    Abydos

  4. DOption (d)

    Alexandria

View answer & explanation

Correct answer

Answer: (d)D.

Alexandria

Why this answer is correct

Correct Answer: Alexandria

 Key Points

Alexandria:

  • Eratosthenes and Hipparchus made significant scientific observations about the Earth's size, shape, and circumference in Alexandria, Egypt.
  • Alexandria was a hub of learning and culture in the ancient world, home to the famous Library of Alexandria.
  • Eratosthenes, who served as the chief librarian, famously calculated the Earth's circumference with remarkable accuracy using observations of the Sun's angle at noon in Alexandria and Syene (modern-day Aswan).

 

Additional Information

 

 

Tanais:

Tanais (now called Azov) was an ancient city located at the mouth of the Don River near the Sea of Azov. It was a significant trading port but not known for groundbreaking scientific observations regarding the Earth's geometry.

Tyras:

Tyras was an ancient Greek colony on the northern coast of the Black Sea, near the modern city of Odessa, Ukraine. While it was an important settlement in the Black Sea region, it was not the site of Eratosthenes and Hipparchus's observations.

Abydos:

Abydos is known as an ancient city located in the region of Thrace on the Hellespont. It is famous for its historical and mythological significance, particularly in relation to the Trojan War stories, but not for contributions to the understanding of Earth's dimensions.

 

  • Alexandria stands out as the correct location because it was a center for scholarly activity during the Hellenistic period. It provided the intellectual environment and resources, such as the Library of Alexandria, that facilitated the groundbreaking work of scholars like Eratosthenes and Hipparchus. Their contributions laid foundational stones in the field of geography and our understanding of the Earth.

Question 12

The actual labour productivity of farms was compared with what could have been achieved under optimizing decision-making by the farmers acting as rational economic persons. Which of the following geographer conducted this study?  

  1. AOption (a)

    Wright

  2. BOption (b)

    White

  3. COption (c)

    Kirk

  4. DOption (d)

    Wolpert

View answer & explanation

Correct answer

Answer: (d)D.

Wolpert

Why this answer is correct

Wolpert

Key Points

  • Julian Wolpert's research in geography often explored the decision-making processes of individuals in rural settings, including farmers.
  • His work examined various spatial economic behaviors, including how farmers' decisions impacted the productivity of their land and their overall economic well-being.
  • The study mentioned fits within the realm of Wolpert's interests in analyzing how theoretical optimal decisions compare with actual behaviors, highlighting the complex interplay between economic theory and human behavior in specific geographic contexts.
  • Therefore, Julian Wolpert (Option 4) is the correct answer.

 

 Additional Information

Wright: Wright is a common last name, and there have been several notable geographers with this surname, but none famously conducted the specific type of study described.

White: Gilbert F. White is well known for his work in natural hazards and human adjustments to floods, rather than agricultural productivity and economic decision-making.

Kirk: William Kirk's work primarily centered around environmental perception and regional geography, which does not directly align with the study described.

Hence, The focus on the actual versus potential productivity based on rational economic decision-making reflects the kind of analysis Julian Wolpert is known for in his contributions to geographic research and theory.

Question 13

Identify the scholar who laid the foundation of the dichotomy of Systematic vs. Regional Geography. 

  1. AOption (a)

    Cook

  2. BOption (b)

    Varenius

  3. COption (c)

    Kant

  4. DOption (d)

    Darwin

View answer & explanation

Correct answer

Answer: (b)B.

Varenius

Why this answer is correct

Varenius:

 Key Points

  • Bernhardus Varenius (Bernhard Varen) is recognized for laying the foundational principles distinguishing between systematic and regional geography.
  • His work, "Geographia Generalis" (1650), systematically categorized geography into general (covering universal principles) and special (focused on specific regions), which later evolved into the systematic vs. regional geography dichotomy.
  • This distinction is crucial for understanding how geographers approach the study of the Earth's surface, with systematic geography focusing on particular phenomena (climate, vegetation, etc.) across the globe, and regional geography concentrating on specific areas, integrating various physical, economic, and cultural aspects

Additional Information

Cook: Captain James Cook, a British explorer, and navigator, known for his three voyages to the Pacific Ocean, where he achieved the first recorded European contact with the eastern coastline of Australia and the Hawaiian Islands, and the first recorded circumnavigation of New Zealand. Though a significant figure in geographical exploration, Cook did not contribute to the theoretical foundation of the dichotomy between systematic and regional geography.

Kant: Immanuel Kant, a German philosopher, made substantial contributions to various fields, including metaphysics, ethics, and aesthetics, but his work in geography, though influential in emphasizing the importance of spatial analysis and the relationship between physical geography and human populations, did not specifically lay the groundwork for the systematic vs. regional geography dichotomy.

<br>

Darwin: Charles Darwin, an English naturalist and geologist, best known for his contributions to evolutionary theory, which has profoundly influenced biological sciences.

  • While Darwin's work demonstrated the importance of geographic distribution for understanding species evolution, it did not directly contribute to the foundational principles of systematic versus regional geography.
<br>

In summary, Bernhardus Varenius is the scholar who distinctly contributed to the foundation of the dichotomy between systematic and regional geography through his work, making him the correct answer. Other mentioned figures, although highly influential in their respective fields and to geographical knowledge, did not specifically establish this fundamental distinction in geographical thought.

Question 14

Who was the author of 17 Volumes of "Geographical Treaties"? 

  1. AOption (a)

    Ptolemy

  2. BOption (b)

    Beatus

  3. COption (c)

    Strabo

  4. DOption (d)

    Jerome

View answer & explanation

Correct answer

Answer: (c)C.

Strabo

Why this answer is correct

Strabo

Key Points

  • Strabo, a Greek geographer, philosopher, and historian who lived approximately from 64 BC to 24 AD, was the author of the "Geographica," a comprehensive work that consisted of 17 volumes.
  • This work is a massive compilation of geographic knowledge of the ancient world and remains one of the most important sources for the study of ancient geography and history.
  • Strabo's Geographica includes descriptions of various peoples and places within the Roman Empire and beyond, offering invaluable insights into the ancient world's geography, political divisions, and cultural practices.

 

Explanation of Incorrect Options:

Ptolemy: An astronomer, geographer, and mathematician who lived in the 2nd century AD. Ptolemy is best known for his work "Geography," which introduced the concept of using longitudinal and latitudinal lines to map the earth's surface. While Ptolemy’s contributions to geographical and astronomical knowledge are profound, he is not the author of the mentioned geographical treaties.

Beatus: Also known as Beatus of Liébana, was an 8th-century Spanish monk best known for the Beatus maps. These maps were part of his commentary on the Book of Revelation but did not amount to a comprehensive geographical treatise like Strabo's work.

Jerome: A Christian priest, theologian, and historian known for his translation of the Bible into Latin (the Vulgate). Jerome contributed significantly to Christian literature and history but did not author a vast geographical treatise.

 Additional Information

  • The "Geographica" is divided into 17 volumes, each of which covers different aspects of the known world in Strabo's time, ranging from Europe and Africa to parts of Asia.
  • This body of work not only provided detailed geographic descriptions but also offered insights into the cultures, political systems, and economic practices of various peoples.
  • Strabo utilized a wide range of sources, including earlier geographers and his own travels, making "Geographica" a foundational text in the field of geography and a critical resource for understanding the Greco-Roman world.

Question 15

Which of the following is not a humanistic geographer? 

  1. AOption (a)

    Tuan

  2. BOption (b)

    Kirk

  3. COption (c)

    Kropotkin

  4. DOption (d)

    Strabo

View answer & explanation

Correct answer

Answer: (d)D.

Strabo

Why this answer is correct

Strabo

Key Points

  • Strabo was an ancient Greek geographer, historian, and philosopher, known for his work "Geographica," which was a descriptive geography of the known world at his time.
  • While Strabo's work is foundational for the history of geography, he does not fit within the realm of humanistic geography.
  • Humanistic geography, as a discipline, emerged in the 20th century and focuses on human perceptions, experiences, and relationships with places, which is distinct from the ethnographic and descriptive geographical work conducted by Strabo.

Additional InformationTuan: Yi-Fu Tuan is widely recognized as one of the pioneers of humanistic geography. His works have emphasized the importance of human experience, perceptions, and emotions in understanding and interpreting places and landscapes. Tuan has contributed significantly to the field with concepts like "topophilia" and "space and place," which directly align with the principles of humanistic geography.

Kirk: While less directly associated with humanistic geography than Tuan, the work of William Kirk involved considerations of human perceptions and experiences in relation to the environment. However, he is more closely associated with other geographical approaches and schools of thought. Despite this, Kirk's contribution to expanding the scope of geography could tangentially relate to the expansion of humanistic perspectives.

Kropotkin: Peter Kropotkin was a geographer, but his contributions were more aligned with political geography and the development of anarchist thought. He is known for his work on mutual aid and his critiques of the state, but these contributions, while impactful in geography and social sciences, do not directly classify him as a humanistic geographer. His work, however, has inspired many to think differently about human-environment relations, akin to some of the foundational themes within humanistic geography.

Question 16

The productivity of rice in Punjab depends on availability of irrigation. Which type of relationship of a system can be explained by the above given statement? 

  1. AOption (a)

    Series relation 

  2. BOption (b)

    Parallel relation 

  3. COption (c)

    Feedback relation 

  4. DOption (d)

    Complex compound relation 

View answer & explanation

Correct answer

Answer: (a)A.

Series relation 

Why this answer is correct

Series Relation:

 Key Points

  • In a series relation within a system, the output of one component acts as the input for the next component.
  • This relationship implies a direct, linear dependency where the functioning or productivity of the entire system relies on the sequential operation of its components.
  • The statement regarding the productivity of rice in Punjab being dependent on the availability of irrigation exemplifies a series relation.
  • The availability of irrigation water is a critical input for rice cultivation, directly affecting its productivity.
  • Without sufficient irrigation, the subsequent process of rice cultivation cannot achieve optimal productivity, highlighting a linear, sequential dependency akin to a series relation.
<br>

Additional Information 

  • Parallel Relation:
  • In a parallel relation, components of a system operate independently of one another. The failure or performance of one component does not directly affect the others. This does not apply to the given statement since the productivity of rice is directly dependent on irrigation, indicating a dependency rather than an independent parallel operation.
  • Feedback Relation:
  • A feedback relation involves a system where the output or result influences the input in a cyclical manner. While agricultural systems can have feedback loops (e.g., the impact of crop yield on future planting decisions), the specific relationship described between irrigation availability and rice productivity is more linear than cyclical, making feedback relation an incorrect choice.
  • Complex Compound Relation:
  • Complex compound relations describe systems with multiple interacting components, where the relationship cannot be easily categorized as solely series, parallel, or feedback. These systems often exhibit characteristics of all three types. Although agricultural systems are complex, the specific cause-and-effect relationship between irrigation and rice productivity is more directly described by a series relation, making the complex compound relation too broad for this context.
<br>

In summary, the direct, linear dependency of rice productivity on irrigation availability in Punjab is best described by a series relation, where the availability of irrigation water is a crucial, sequential input for the cultivation process. Other options represent different types of system relationships that do not as accurately describe the specific dependency outlined in the statement.

Question 17

Which one of the following sets of book and author is wrongly matched? 

  1. AOption (a)

    Human Geography: A welfare Approach - D. M. Smith 

  2. BOption (b)

     Geography and Geographers - D. Harvey 

  3. COption (c)

    Radical Geography - R. Peet 

  4. DOption (d)

    A Geographical introduction to History - L. Febvre 

View answer & explanation

Correct answer

Answer: (b)B.

 Geography and Geographers - D. Harvey 

Why this answer is correct

Geography and Geographers - D. Harvey 

Key Points

  • Human Geography: A Welfare Approach - D. M. Smith: This is correctly matched. D. M. (David M.) Smith is known for his contributions to discussions on welfare in the context of human geography.
  • Geography and Geographers - D. Harvey: This is incorrectly matched. "Geography and Geographers: Anglo-American Human Geography since 1945" is actually authored by Ron Johnston and James Sidaway. David Harvey is a renowned geographer known for his contributions to many areas of human geography, including critical geography and Marxism, but he is not the author of "Geography and Geographers.”
  • Radical Geography - R. Peet: This is correctly matched. Richard Peet is known for his work in critical geography, and he has indeed contributed significantly to the area known as radical geography.
  • A Geographical Introduction to History - L. Febvre: This is correctly matched. Lucien Febvre, a prominent historian associated with the Annales School, authored this work, which emphasizes the role of geography in the understanding of history.

 

Therefore, the correct answer is Option 2, as "Geography and Geographers" is actually written by Ron Johnston and James Sidaway, not D. Harvey.

Question 18

Which of the following information is used in altimetric frequency graph? 

  1. AOption (a)

    Spot height 

  2. BOption (b)

    Density of population 

  3. COption (c)

    Contour lines 

  4. DOption (d)

    Cumulative frequency 

View answer & explanation

Correct answer

Answer: (a)A.

Spot height 

Why this answer is correct

Spot height 

Key Points

  • Spot height is used in altimetric frequency graphs to provide specific elevation points on a map.
  • These points help in understanding the vertical dimension of the terrain being represented.
  • Spot heights are precise measures of elevation and are crucial for creating an accurate altimetric frequency graph.
<br>

 Additional Information

  • Density of population is not used in altimetric frequency graphs.
  • These graphs focus on the physical geography of an area, specifically its elevation, rather than demographic information like population density.
  • Contour lines, while they are used to represent elevation on a map, do not directly contribute to the construction of an altimetric frequency graph. Contour lines give a continuous representation of elevation, showing the shape and height of the terrain, but the graph itself relies on discrete elevation points like spot heights.
  • Cumulative frequency is a statistical tool used to understand data distribution, showing the number of observations below a particular value. It is not directly related to the construction of altimetric frequency graphs, which are concerned with representing elevation data rather than statistical distributions of observations.
<br>

In summary, spot heights are the correct information used in altimetric frequency graphs because they provide discrete, exact elevation points necessary for plotting the vertical profile of terrain. Other options like population density, contour lines, and cumulative frequency do not directly contribute to the creation of these graphs.

Question 19

Which type of maps are called cartograms? 

  1. AOption (a)

    Maps on which very minute details about very small areas like towns and villages are given. 

  2. BOption (b)

    The million sheets of the Survey of India. 

  3. COption (c)

    Maps on which diagrams and graphs are superimposed to show the spatial distribution of data. 

  4. DOption (d)

    A rough drawing without scale. 

View answer & explanation

Correct answer

Answer: (c)C.

Maps on which diagrams and graphs are superimposed to show the spatial distribution of data. 

Why this answer is correct

Maps on which diagrams and graphs are superimposed to show the spatial distribution of data.

Key Points

  • Cartograms are a specific type of thematic map where the geometry or space of the map is distorted in order to convey the information of an alternate variable, such as population size, economic indicators, or any other attribute of interest.
  • These maps transform the space according to the data, rather than according to actual geographic areas.
  • This transformation often results in maps that look significantly different from traditional geographic maps, as areas are resized according to the data they represent, not their actual landmass or geographic size

 

Explanation of Incorrect Options:

Maps on which very minute details about very small areas like towns and villages are given: This option describes large-scale maps or detailed topographic maps, which are designed to represent very small areas with a high level of detail. These maps are focused on geographical accuracy and precision in representing the physical features and measurements of a specific area, rather than distorting space to show statistical data, as cartograms do.

The million sheets of the Survey of India: This option likely refers to topographic maps produced by national agencies such as the Survey of India, which are standardized sheets used for various purposes including military, civil, and development planning. These maps are created to be geographically accurate and are divided into sheets for systematic coverage of a country, rather than manipulating geographic proportions to represent statistical data.

A rough drawing without scale: This option describes sketch maps or informal maps that are drawn without regard to scale, projection, or precise geographical accuracy. These are often quick, hand-drawn representations of an area's basic layout or features made for informal or temporary use. Unlike cartograms, these maps do not systematically distort geographic space to represent statistical data; instead, they may lack detail and accuracy altogether.

 Additional Information

  • Cartograms can be a powerful visual tool for representing complex data in a way that is immediately visually apparent, even to those without a deep understanding of traditional map reading or the underlying data.
  • They allow comparisons across different areas or countries by directly visualizing the data of interest, making complex demographic, economic, or social information accessible through spatial distortion.
  • This method of mapping provides unique insights into the data being represented, emphasizing the importance of the mapped variable over geographical accuracy.

Question 20

Which of the following Indian language group matches correctly with its speech area? 

  1. AOption (a)

    North Dravidian - Odisha 

  2. BOption (b)

    Dardic - Nicobar Islands  

  3. COption (c)

    Mon-Khmer - Assam 

  4. DOption (d)

    Munda - Jammu and Kashmir 

View answer & explanation

Correct answer

Answer: (a)A.

North Dravidian - Odisha 

Why this answer is correct

North Dravidian - Odisha:

 Key Points

  • This is the correct match.
  • The North Dravidian languages, including languages like Kurukh and Malto, are primarily spoken in parts of eastern India, including areas in Odisha.
  • This region has linguistic diversity that includes Dravidian languages, even though they are more commonly associated with southern India.
<br>

 Additional InformationDardic - Nicobar Islands: This option is incorrect. The Dardic languages are part of the Indo-Aryan language family and are primarily spoken in the northern regions of Pakistan and in Jammu and Kashmir in India, not in the Nicobar Islands. The Nicobar Islands, located in the Bay of Bengal, have their own indigenous languages unrelated to Dardic languages.

<br>

Mon-Khmer - Assam: This option is incorrect. Mon-Khmer languages are a branch of the Austroasiatic language family. While some Austroasiatic languages, like Khasi and Munda languages, are spoken in India, the Mon-Khmer languages are predominantly found in Southeast Asia, not in Assam. Assam is predominantly home to Indo-Aryan and Tibeto-Burman languages.

<br>

Munda - Jammu and Kashmir: This option is incorrect. Munda languages are part of the Austroasiatic language family, but they are primarily spoken in the central and eastern parts of India, such as in Jharkhand, Chhattisgarh, West Bengal, and Odisha, not in Jammu and Kashmir. Jammu and Kashmir are more associated with Dardic and Tibeto-Burman languages.

<br>

In summary, the correct match is North Dravidian languages being spoken in Odisha, as it aligns with the geographical distribution of the Dravidian language family in India. The other options incorrectly match language families with regions where they are not primarily spoken.

Question 21

Which one of the following pair is wrongly matched? 

Pass/GapConnected Cities
1.Shencottah gapTiruelveli
2.Palghat gapCoimbatore
3.Burhanpur gapItarsi
4.Thal ghat gapAhmedabad

  2. BOption (b)

    2

  3. COption (c)

    3

  4. DOption (d)

    4

View answer & explanation

Correct answer

Answer: (d)D.

4

Why this answer is correct

4

 Key Points

Option 4: Thal Ghat Gap - Ahmedabad

This pairing is incorrect, making option 4 the right answer. The Thal Ghat, also known as Thalghat, is a mountain pass in Maharashtra that facilitates railway and road transportation from the Mumbai region to the interior parts of Maharashtra and beyond. It is primarily associated with cities like Nashik and Kalyan, not Ahmedabad. Ahmedabad, located in Gujarat, is not directly connected via the Thal Ghat gap, which makes this pairing wrongly matched.

Additional Information

Option 1: Shencottah Gap - Tirunelveli 

This pair is correctly matched. The Shencottah Gap is a natural pass in the Western Ghats mountain range near the town of Shencottah, Tamil Nadu. It connects the state of Tamil Nadu with Kerala and lies close to Tirunelveli, making this pairing accurate.

<br>
  • Option 2: Palghat Gap - Coimbatore

This pairing is also correct. The Palghat Gap is a low mountain pass in the Western Ghats between Coimbatore in Tamil Nadu and Palakkad in Kerala. It serves as an important pass that facilitates transportation between these regions.

<br>
  • Option 3: Burhanpur Gap - Itarsi

This option is correct. The Burhanpur Gap refers to a region facilitating movement in central India, but it's less commonly referred to in geographical texts in comparison to the other gaps mentioned. Itarsi does not directly relate to a specific "gap," but rather is a significant railway junction in Madhya Pradesh, making the direct connection to a "Burhanpur Gap" less clear. However, there is no widely recognized geographical feature known as the "Burhanpur Gap" directly linking these cities, making this option potentially confusing but not the incorrect match based on the provided options.

<br>

Summary: The incorrect pairing is the Thal Ghat Gap with Ahmedabad, as Thal Ghat is linked with areas in Maharashtra rather than Gujarat, making option 4 the correct choice. Other options represent more accurate pairings of passes/gaps with nearby or connected cities, even though the specific details of each may vary in terms of direct geographical or infrastructural connections.

Question 22

  1. AOption (a)

    Kal-Baisakhi - West Bengal 

  2. BOption (b)

    Cherry-Blossom - Andhra pradesh 

  3. COption (c)

    Mango showers - Karnataka 

  4. DOption (d)

    Bardoli Chheerha - Assam 

View answer & explanation

Correct answer

Answer: (b)B.

Cherry-Blossom - Andhra pradesh 

Why this answer is correct

Correct Answer: 2) Cherry-Blossom - Andhra Pradesh

 Key Points

  • This is incorrectly matched. Cherry blossoms are famously associated with regions in the temperate zone, especially Japan.
  • In India, cherry blossoms are more commonly associated with states in the North-East, particularly Meghalaya, not Andhra Pradesh.
  • This festival marks the unique blooming season of Cherry Blossoms in the region.
  • Andhra Pradesh is known for its rich cultural heritage and festivals but not for Cherry Blossoms.
<br>

Additional Information 

1) Kal-Baisakhi - West Bengal: This is correctly matched. Kal-Baisakhi refers to the pre-monsoon or summer showers that are common in West Bengal and the eastern parts of India. These showers are crucial for the crops and are known for their sudden onset, bringing relief from the sweltering summer heat.

<br>

3) Mango Showers - Karnataka: Correctly matched. Mango showers refer to the pre-monsoon rainfall that occurs in parts of South India, including Karnataka. These showers are beneficial for the early ripening of mangoes, hence the name. They are also experienced in other parts of the Indian subcontinent.

<br>

4) Bardoli Chheerha - Assam: This is also correctly matched. Bardoli Chheerha is a specific type of rain or weather pattern experienced in Assam. It's part of the local terminology and weather culture, indicative of the region's unique climatic conditions and agricultural practices.

<br>

Conclusion: The wrongly matched pair is the Cherry-Blossom festival being associated with Andhra Pradesh, as this festival is significant in regions like Shillong, Meghalaya, where Cherry Blossoms are a natural spectacle, not in Andhra Pradesh. Other options correctly match the regional weather phenomena or cultural practices with their respective areas.

Question 23

In which of the layers temperature decreases as altitude increases?

A. Thermosphere

B. Troposphere

C. Mesosphere

D. Stratosphere

Choose the correct answer from the options given below:

  1. AOption (a)

    A and B only  

  2. BOption (b)

    B and C only 

  3. COption (c)

    B and D only

  4. DOption (d)

    C and D only

View answer & explanation

Correct answer

Answer: (b)B.

B and C only 

Why this answer is correct

Answer: B and C only

Key Points

 

Troposphere:

  • This is the lowest layer of the Earth's atmosphere.
  • It starts at the Earth's surface and extends up to 8 to 15 kilometers (5 to 9 miles) high.
  • The temperature decreases with altitude in the troposphere. This is because it is heated from the ground up; the surface of the Earth absorbs sunlight and warms the layers of the atmosphere above it.

Mesosphere:

  • Located above the stratosphere, the mesosphere extends from about 50 to 85 kilometers (31 to 53 miles) above the Earth's surface.
  • In this layer, temperature decreases with altitude. The top of the mesosphere is the coldest part of Earth's atmosphere.

Stratosphere:

  • Situated above the troposphere and below the mesosphere, it extends from about 10 to 50 kilometers (6 to 31 miles) above the Earth's surface.
  • The temperature in the stratosphere increases with altitude. This increase is due to the absorption of ultraviolet radiation by the ozone layer, which heats this part of the atmosphere.

Thermosphere:

  • This layer is above the mesosphere, extending from about 85 kilometers (53 miles) to 600 kilometers (372 miles) above the Earth.
  • In the thermosphere, temperature increases with altitude. The temperature can rise up to 2,500 km  or higher. The increase in temperature is due to the absorption of extreme ultraviolet and X-ray radiation from the Sun.

 

Hence, The temperature decreases with altitude in the troposphere and mesosphere, making option 2 (B and C only) the correct choice. The stratosphere and thermosphere experience an increase in temperature with altitude, which is why options involving these layers are incorrect.

Question 24

A. Grassland

B. Wetland

C. Delta

D. Forests

Choose the correct answer from the options given below:

  1. AOption (a)

    A only

  2. BOption (b)

    A and B only

  3. COption (c)

    B and C only

  4. DOption (d)

    B and D only

View answer & explanation

Correct answer

Answer: (c)C.

B and C only

Why this answer is correct

Answer: B and C only (Wetland and Delta)

<br>

Key Points

 

Wetlands:

  • These are areas where water covers the soil, or is present either at or near the surface of the soil all year or for varying periods of time during the year, including during the growing season.
  • Wetlands play a crucial role in the environment by acting as natural water purifiers, providing wildlife habitats, and serving as buffers to prevent flooding.
  • Examples include marshes, swamps, and bogs.
<br>

Delta:

  • A delta is a landform that forms from deposition of sediment carried by a river as the flow leaves its mouth and enters slower-moving or standing water.
  • This can be a lake, sea, ocean, or estuary. Deltas are important as they support diverse ecosystems, are rich in biodiversity, and are often fertile areas for agriculture.
<br>

Additional Information 

Grassland:

  • Grasslands are terrestrial ecosystems characterized by vast open areas dominated by grasses.
  • They are not aquatic ecosystems, but they can include riparian zones which are interfaces between land and a river or stream.
<br>

Forests:

  • Forests are large areas dominated by trees.
  • They are primarily terrestrial ecosystems.
  • While they can contain water bodies like rivers and lakes, the ecosystem as a whole is not considered aquatic.
<br>

Hence, wetlands and deltas are aquatic ecosystems because they are characterized by the presence of water either at or near the surface for significant periods, making them distinct from predominantly terrestrial ecosystems like grasslands and forests.

  4. DOption (d)

    Papanasam - Tamraparni river 

View answer & explanation

Correct answer

Answer: (a)A.

Matatila - Banas river 

Why this answer is correct

The correct answer is Matatila - Banas river 

Key Points

  • The Matatila Dam is built on the Betwa River, not the Banas river. The other three projects are correctly matched. The Banasagar project lies on the Sone river, the Ukai Project is on the Tapi river, and the Papanasam project is on the Tamraparni river.

Correct Matchings and Explanations:

  • Banasagar - Sone river: This is correctly matched. The Banasagar Dam is a multipurpose river valley project on the Sone River, which spans several Indian states including Madhya Pradesh, Uttar Pradesh, and Bihar.
  • Ukai - Tapi river: This is correctly matched. The Ukai Dam is located on the Tapi (or Tapti) River in Gujarat, India. It is a major multipurpose dam that serves purposes such as flood control, irrigation, and hydroelectric power generation.
  • Papanasam - Tamraparni river: This is correctly matched. The Papanasam Dam is located on the Tamraparni River in Tamil Nadu, India. It is used for irrigation and water supply purposes.

 Additional Information

Multipurpose projects are typically designed to serve several functions such as irrigation, hydroelectric power generation, flood control, water supply for drinking and industrial uses, and sometimes, even recreation. In India, these projects play a crucial role in optimizing the use of water resources in the context of the country's varied climate and topography.

    Konkan region 

  4. DOption (d)

    Godavari basin 

View answer & explanation

Correct answer

Answer: (a)A.

Bundelkhand region 

Why this answer is correct

Bundelkhand region:

 Key Points

  • This region lies in the central part of India, predominantly covering parts of Uttar Pradesh and Madhya Pradesh.
  • It is known to be in a low seismic zone, meaning it is less prone to earthquakes compared to other parts of India. This is due to its location away from the boundaries of the Indian plate where most seismic activities occur.
  • The geological structure and the rock formations in this area are such that they do not significantly amplify seismic waves.

Additional Information 

Ganga region:

  • the Ganga basin, it's important to note that the Ganga basin spans a large area with varying seismic sensitivities.
  • Some parts are more prone to seismic activities than others, making it generally more seismically active than the Bundelkhand region.
<br>

Konkan region:

  • Located along the western coast of India, the Konkan region is known for its scenic beauty and coastal geography.
  • While it is not in the highest seismic zone, it has experienced minor to moderate earthquakes. Its proximity to the coast also makes it vulnerable to other natural events like tsunamis which are related to undersea earthquakes.
<br>

Godavari basin:

  • This basin stretches over several states in India and is one of the largest river basins in the country.
  • Parts of the Godavari basin are prone to seismic activities, though not as high as the Himalayan region. The seismic sensitivity varies across the basin, with some areas being more prone to earthquakes than others.
<br>

In summary, the Bundelkhand region is considered to be in the lowest seismic sensitive zone among the options provided, due to its geological characteristics and location which make it less prone to seismic activities compared to the other regions mentioned.

Question 27

Which of the following are examples of chemical weathering?

A. Movement of rock along fracture

B. Rusting of Iron

C. Breaking of Feldspar to clay

D. Acid action

Choose the correct answer from the options given below:

  1. AOption (a)

    A and B only

  2. BOption (b)

    B and C only

  3. COption (c)

    A, B and C only

  4. DOption (d)

    B, C and D only

View answer & explanation

Correct answer

Answer: (d)D.

B, C and D only

Why this answer is correct

  • Chemical weathering involves the breakdown of rocks and minerals through chemical reactions, rather than physical processes.
<br>
  • Option 1: A and B only
  • This option is incorrectly listed as the correct answer in the provided data. Movement of rock along fracture (A) is an example of physical or mechanical weathering, not chemical weathering. Rusting of Iron (B), however, is a form of chemical weathering as it involves a chemical reaction between iron, oxygen, and water leading to the formation of iron oxide.
<br>
  • Option 2: B and C only
  • This option correctly identifies examples of chemical weathering. Rusting of Iron (B) involves chemical reactions, as mentioned earlier. Breaking of Feldspar to clay (C) is another example of chemical weathering, where feldspar reacts with water and carbon dioxide to form clay minerals through hydrolysis.
<br>
  • Option 3: A, B, and C only
  • This option incorrectly includes A (Movement of rock along fracture), which is an example of physical weathering, not chemical.
<br>
  • Option 4: B, C, and D only
  • This is the correct option. Rusting of Iron (B), Breaking of Feldspar to clay (C), and Acid action (D) are all examples of chemical weathering. Acid action refers to the reaction of rock minerals with acidic solutions, which can occur through natural processes like the dissolution of carbon dioxide in rainwater forming carbonic acid, leading to the chemical breakdown of rocks.
<br>
  • Incorrect Options Overview:
  • Option 1: Incorrect because movement of rock along a fracture is physical weathering.
  • Option 3: Includes an example of physical weathering (A), making it incorrect.
  • Option 5: Not applicable as it doesn't provide any choices.
<br>
  • Conclusion: Chemical weathering involves the alteration of rock materials through chemical reactions, such as the rusting of iron, conversion of feldspar to clay, and the action of acids on rocks. The presence of water and acids plays a significant role in these processes. Physical weathering, on the other hand, involves the physical breaking down of rocks without changing their chemical composition.

Question 28

Which of the following statements are true about aerosols in the atmosphere?

A. Aerosols include sea salts, fine soil, smoke, pollens, soot.

B. Aerosols in the air contribute to the various hues of red and orange at sunrise and sunset.

C. The concentration of aerosols is maximum in mesosphere.

D. Aerosols act as surfaces on which water vapour condenses.

Choose the correct answer from the options given below:

  1. AOption (a)

    A and C only

  2. BOption (b)

    B and C only

  3. COption (c)

    A, B and D only

  4. DOption (d)

    C and D only

View answer & explanation

Correct answer

Answer: (c)C.

A, B and D only

Why this answer is correct

A, B and D only

Key Points

  • A. True. Aerosols in the atmosphere encompass a wide variety of particles, including sea salts, fine soil particles, smoke from fires, pollen, and soot from combustion processes.
  • These aerosols can come from both natural sources, such as dust storms and sea spray, and anthropogenic (human-made) sources, such as industrial emissions and vehicle exhausts.
  • B. True. Aerosols play a significant role in scattering sunlight, which affects the colors we see at sunrise and sunset.
  • The scattering of light by aerosols and other particles in the atmosphere can lead to the sky taking on various hues of red, orange, and pink.
  • This phenomenon occurs because particles in the atmosphere scatter shorter wavelengths (blue and green) more than longer wavelengths (red and orange), which, when the sun is low on the horizon, results in the predominance of reds and oranges in the sky.
  • D. True. Aerosols act as cloud condensation nuclei (CCN), providing surfaces on which water vapor can condense to form cloud droplets.
  • This is a crucial process in the formation of clouds in the Earth's atmosphere. The presence of aerosols affects cloud properties, including their reflectivity (albedo), longevity, and the potential for precipitation.
  • Through their role in cloud formation and modification, aerosols have a significant impact on the Earth's weather and climate.

 Additional InformationC. False.

  • The concentration of aerosols is not maximum in the mesosphere. Aerosols are primarily concentrated in the troposphere, the lowest layer of Earth's atmosphere, which extends from the Earth's surface up to about 8 to 15 kilometers (5 to 9 miles) into the atmosphere.
  • The troposphere is where most of the Earth's weather phenomena take place, and it contains the majority of the atmospheric aerosols due to the proximity to their sources on the surface and within the lower atmosphere.
  • The mesosphere, which is above the stratosphere and extends from about 50 to 85 kilometers (31 to 53 miles) altitude, has a much lower concentration of aerosols.

 

 Important Points

  • Aerosols in the atmosphere are of great interest to scientists not only because of their immediate effects on air quality and human health but also because of their complex interactions with climate systems.
  • They influence the Earth's radiation balance by directly scattering and absorbing sunlight (direct effect) and indirectly through their role in cloud formation and properties (indirect effect).
  • Their impact on climate can be cooling or warming, depending on factors like the type of aerosols, their location, and the underlying surface.
  • Nevertheless, their overall effect on global temperature is considered to be a net cooling, partially offsetting the warming impact of greenhouse gases.
  • However, the extent of aerosol effects on climate is subject to significant scientific research and debate, making it one of the largest sources of uncertainty in climate modeling and prediction.

  4. DOption (d)

    C and D only

View answer & explanation

Correct answer

Answer: (c)C.

B and D only

Why this answer is correct

The correct answer is B and D only.

 Key Points

  • B. True. The statement "It is not associated with the philosophy of positivism" is NOT true about spatial analysis, making the original statement (B as stated in the question) incorrect.
  • Spatial analysis is closely associated with the philosophy of positivism, which emphasizes the importance of observable evidence and statistical analysis in the study of social and natural phenomena.
  • Positivism underpins much of the quantitative approach employed in spatial analysis, focusing on using empirical data and objective methods to understand spatial relationships and patterns.
  • D. True. The statement "It got popularity due to deterministic approach in geography" is NOT true about spatial analysis, making the original statement (D as stated in the question) incorrect. ]
  • Spatial analysis gained popularity not solely because of a deterministic approach but largely due to the advent of computer technology, which allowed for the handling and analysis of large spatial datasets.
  • Moreover, spatial analysis encompasses both deterministic and probabilistic models to explain and predict spatial phenomena.
  • Its popularity stems from its ability to apply complex analytical techniques to understand spatial patterns, relationships, and processes, going beyond deterministic approaches to include stochastic and explorative methods as well.

Additional Information

A. False (making the statement true as per the question's requirement). The application of quantitative techniques to analyze geographic or spatial data indeed refers to spatial analysis. Spatial analysis encompasses a range of techniques and processes used to understand patterns, relationships, and trends across geographical spaces. This definition aligns well with the common understanding of what spatial analysis entails.

C. False (making the statement true as per the question's requirement). The generalization arrived at with the application of spatial analysis is indeed based on factors such as direction, distance, and connection. These are fundamental concepts in spatial analysis, helping to understand and quantify the spatial relationships between different entities or phenomena across geographical space.

Therefore, the statements B and D are NOT true about spatial analysis, making option 3 the correct answer.

  • A . Correct. Agenda 21 was indeed adopted at the 1992 Earth Summit held in Rio de Janeiro, Brazil. Agenda 21 is a comprehensive plan of action to be taken globally, nationally, and locally by organizations of the United Nations System, Governments, and Major Groups in every area in which humans impact the environment. Its adoption marked a significant step toward sustainable development worldwide.
  • D. Correct. The Commission on Sustainable Development (CSD) was established in December 1992 to ensure effective follow-up of the United Nations Conference on Environment and Development, or the Earth Summit, held in Rio de Janeiro. Its purpose was to monitor and report on implementation of the Earth Summit agreements at the local, national, international, and regional levels.
  • B. Incorrect. The Montreal Protocol was not adopted at the 1992 Earth Summit. Instead, it was adopted earlier, on September 16, 1987, and came into force on January 1, 1989. The Montreal Protocol on Substances that Deplete the Ozone Layer is an international treaty designed to protect the ozone layer by phasing out the production of numerous substances believed to be responsible for ozone depletion.
  • C. Incorrect. The main aim of the Montreal Protocol was not to reduce carbon dioxide emissions but rather to phase out the production and consumption of ozone-depleting substances (ODS) such as chlorofluorocarbons (CFCs), halons, and other chemicals. While reducing CO2 emissions is crucial for combatting climate change, the focus of the Montreal Protocol has specifically been on substances that harm the ozone layer.

 

Additional Information

  • Agenda 21 focuses on sustainable development in various domains including conservation and management of resources, combating poverty, changing consumption patterns, promoting health, and achieving a more sustainable population. It is not a legally binding agreement, but rather a detailed plan of action that governments at all levels are encouraged to adopt.
  • The Montreal Protocol is considered one of the most successful environmental agreements because it has led to significant reductions in substances that deplete the ozone layer, contributing to its gradual recovery.
  • The Commission on Sustainable Development (CSD) was critical in promoting sustainable development initiatives following the 1992 Earth Summit. However, in 2013, it was replaced by the High-Level Political Forum on Sustainable Development, established by the United Nations Conference on Sustainable Development (Rio+20), to provide political leadership and recommendations on sustainable development.

A, B and E only

Why this answer is correct

The correct answer is: A, B, and E only

Key Points

 

  • Changes in forms of transport (A):
  • This statement is correct.
  • Changes in transportation methods can lead to urban decline if a city becomes less accessible or less connected. For example, the rise of automobile travel over trains might diminish the importance of cities built around rail hubs.
  • Exhaustion of mineral deposits (B):
  • This statement is correct.
  • Cities that rely heavily on mining and extraction industries can face economic decline when the local mineral resources are depleted, leading to job losses and reduced economic activity.
  • Competition from nearby towns (E):
  • This statement is correct.
  • Nearby towns and cities that offer better opportunities, amenities, or living conditions can attract residents and businesses away from an urban area, contributing to its decline.
  • Climate change (C):
  • This statement is incorrect.
  • Though climate change can impact urban areas significantly, it is not as directly attributed to urban decline in the context of socio-economic factors compared to others listed.
  • City governance (D):
  • This statement is incorrect.
  • While poor city governance can contribute to urban problems, it is a broader factor that encompasses various aspects of urban management and policy rather than a primary cause of urban decline.

Additional Information

  • Urban Decline:
  • Urban decline, also known as urban decay, refers to the deterioration of a city or part of a city due to various socio-economic factors.
  • Factors include economic redistribution, demographic shifts, changes in transport, and loss of employment due to industrial changes.
  • Impact of Transport Changes:
  • Shifts in transportation can significantly affect urban viability, particularly if infrastructure investments do not keep pace with changing modes of travel.
  • Role of Competition:
  • Competition from neighboring towns and cities can draw away resources and populations, leading to a cycle of decline.

Key Points

  • A . Option of 'others' - other than male/female: This is correct. The 2011 Census of India indeed introduced an "Other" category to accommodate individuals who do not identify exclusively as male or female, recognizing the presence and identity of transgender people. This was a significant step towards inclusivity in data collection.
  • D. Four new codes on disability: This is correct. To improve data on disability and make it more comprehensive, the 2011 Census introduced four new codes to categorize different types of disabilities more accurately, enabling better understanding and provision for the needs of disabled individuals.
  • E. Information about rentiers: Correct. The 2011 Census included new information collection about rentiers, individuals who derive income from property or investments, as part of its broader effort to improve data on economic activities and status. This addition helps to paint a more complete picture of economic conditions and sources of income beyond traditional employment.

 

 Additional Information

  • The Census of India is conducted every 10 years and is one of the largest administrative exercises performed worldwide.
  • Each census seeks not only to count the population but also to collect comprehensive demographic, social, and economic data.
  • This data serves a wide range of purposes, including planning for education, healthcare, and infrastructure, as well as informing policy decisions and resource allocation.
  • The 2011 Census was particularly noteworthy for introducing several new measures to improve the quality and inclusivity of the data collected, as seen in options A, D, and E.

Correct answer

Answer: (d)D.

C, D and E only

Why this answer is correct

The correct answer is Option 4) C, D and E only.

Key Points

A . Mahogany, Ebony and Rosewood are main trees of the Tropical Wet Evergreen Forest: This statement is correct. Tropical wet evergreen forests, found in regions with high rainfall, are home to a diverse range of tree species, including mahogany, ebony, and rosewood. These trees are known for their dense hardwood and are highly valuable for furniture and craftwork.

B. Sal and Teak are major species of the Tropical Monsoon Forest: This statement is NOT correct in the strictest sense. Although sal (Shorea robusta) is indeed a major species found in the tropical monsoon (or deciduous) forests of India and the subcontinent, teak (Tectona grandis), while it can be found in a variety of forest types including monsoon forests, is more typically associated with tropical dry forests. The inclusion of teak alongside sal as major species of specifically tropical monsoon forests may not accurately represent their ecological distributions.

C. Chestnut tree is known as "axe-breaker" in Chaco region of Paraguay and southern Brazil: This statement is NOT correct. The term "axe-breaker" is more commonly associated with Quebracho trees, not chestnut trees. Quebracho (which literally means "axe-breaker") refers to several tree species found in South America known for their hard wood. Chestnut trees are not typically referred to by this name.

D. Chinchona tree bark is used to manufacture chewing gum: This statement is NOT correct. Chinchona tree bark is famous for containing quinine, an alkaloid used to treat malaria, not for being a component in chewing gum. The sapodilla tree (from which chicle, a natural gum base, is harvested) might be associated with the production of traditional chewing gum, not the chinchona tree.

E. Tannin is found in the bark of hemlock, mangrove species and teak trees: This statement is Not correct. Tannins are a class of astringent, polyphenolic biomolecules that are found in many plant tissues, They are widely used in tanning leather and in some traditional medicines.

Therefore, the statements that are NOT correct are options B, C, D and E making Option 4 the correct answer.

Correct answer

Answer: (c)C.

A and C only

Why this answer is correct

The Correct answer is: A and C only

Key Points

  • Ibadan:
  • This statement is correct.
  • Ibadan, located in southwestern Nigeria, is a historic city situated on a hilltop. The city was originally a fortified site and its location on a hill was strategically chosen for defense purposes.
  • Its high elevation provided both visibility and a strong defensive advantage against potential invaders in ancient times.
  • Montreal:
  • This statement is incorrect.
  • Montreal, a major city in Canada, is located on the Island of Montreal and is not situated on a hilltop. It is more of a flat island with a diverse geography, but not specifically known for its elevated or hilltop location for defensive purposes.
  • Edinburgh:
  • This statement is correct.
  • Edinburgh, the capital of Scotland, is often classified as a "hilltop site city." The city is built around a series of hills, including Castle Rock, which was historically important for defense.
  • The famous Edinburgh Castle, perched on top of a volcanic hill, exemplifies the strategic hilltop positioning used for defense.
  • New York:
  • This statement is incorrect.
  • New York is not classified as a hilltop city. It is known for its coastal location and its islands, and though it has some hilly terrain, it does not have the elevated strategic positioning typically seen in hilltop cities.
  • Hamburg:
  • This statement is incorrect.
  • Hamburg, located in northern Germany, is also not classified as a hilltop city. The city's geography is dominated by its rivers and flat plains rather than by elevated positions used for defense.

Additional Information

  • Hilltop Cities:
  • Hilltop cities are often characterized by their strategic elevation, which provided an advantage in defense. Historically, such sites were chosen for their ability to offer clear sightlines, fortifications, and natural defenses.
  • Examples of hilltop cities include ancient capitals such as Rome, Athens, and Edinburgh, where their elevated positions offered security against invaders and control over surrounding areas.
  • Defensive Sites:
  • Defensive sites are locations that provide military or strategic advantages due to their geography. Hilltops, with their commanding views and difficulty of access, were often chosen for fortifications and settlements in ancient times.

Question 35

According to Ullmann the necessary elements of spatial interaction include:

A. Complementarity

B. Sustainability

C. Convenience

D. Intervening opportunities

E. Transferability

Choose the correct answer from the options given below:

  1. AOption (a)

    A, C and E only

  2. BOption (b)

    C, D and E only

  3. COption (c)

    A, D and E only

  4. DOption (d)

    A, B and C only

View answer & explanation

Correct answer

Answer: (c)C.

A, D and E only

Why this answer is correct

Correct Answer: A, D and E only

 

Key Points

A. Complementarity: This refers to the existence of a demand in one place and a supply in another, which complements each other. For spatial interaction to occur, there must be a need or desire for goods, services, or other interactions in one area that another area can provide. Complementarity is a fundamental principle as it establishes the potential for interactions between different places.

D. Intervening Opportunities: This concept suggests that the presence of a nearer opportunity that satisfies the demand or need can significantly influence or reduce the spatial interaction between distant places. Intervening opportunities can divert or alter the flow of goods, services, or information, making them critical in understanding spatial dynamics.

E. Transferability: This refers to the ease with which goods, services, ideas, or people can be transported or communicated from one area to another. The costs (in terms of money, time, and effort) associated with the movement must be bearable relative to the value of the interaction. High transferability facilitates greater spatial interaction.

 Additional InformationAccording to Edward Ullmann's theory of spatial interaction, the necessary elements that facilitate or drive the process are complementarity (A), intervening opportunities (D), and transferability (E). These elements collectively explain why and how spatial interactions occur, focusing on the economic principles that allow for goods, services, information, and people to move between different geographical locations.

Therefore, the correct answer, which includes only the necessary elements of spatial interaction as identified by Ullmann, is Option 3) A, D, and E only.

Answer: (c)C.

C, D and E only

Why this answer is correct

C, D and E only

In political geography, the study of a state involves various criteria that distinguish it as a political entity with sovereignty and control over a particular area.

Key Points

C. Definite portion of earth's land surface with recognized limits: One of the primary characteristics of a state is having a defined territory with clear and recognized borders. This territoriality is fundamental for the state's identity and governance.

D. Administrative system to perform functions needed or desired by the people: A state requires an administrative and governmental structure to carry out laws, policies, and services for its citizens. This system represents the state's capacity to maintain order and provide for its population.

E. Organized means of transmitting goods, people, and ideas from one part of the territory to another: While important for the functioning of a state, this criterion is more related to infrastructure and logistics within the state rather than a defining feature of what constitutes a state in political geography.

Additional Information 

 

A. Power over the people of an area unrestrained by laws originating from outside the area: This refers to the concept of sovereignty, It highlights the state's ultimate authority over its territory and population, independent of external influences.

B. Recognition by a significant portion of the international community: International recognition is important for a state's legitimacy on the global stage. It helps establish diplomatic relations and participate in international organizations.

Correct answer

Answer: (b)B.

A, B and E only

Why this answer is correct

A, B and E only

Jati refers to the thousands of clans, tribes, communities and sub-communities in India. It is a term used across the Indian subcontinent, signifying the traditional social stratification system.

Key Points

A. Jatis are hierarchically graded: This is correct. Jatis have traditionally been organized in a hierarchical system, with each Jati having a specific place in the social ladder, often influenced by ritual status, purity, and occupation. 

B. They invariably have a Jati-linked occupation: This statement is broadly accurate. Historically, Jatis were associated with specific occupations, which were hereditary. While this occupational linkage has weakened over time due to modernization and socio-economic changes, the association remains a significant aspect of Jati identity.

E. Jatis are endogamous unit: This is correct. One of the defining features of a Jati is endogamy, meaning members are expected to marry within their Jati. This practice helps maintain the distinct identity and continuity of the Jati over generations.

<br>

The concept of Jati is integral to understanding the complex social structure in the Indian subcontinent, reflecting both historical practices and the evolution of society in areas such as occupational flexibility, social mobility, and cultural practices.

Correct answer

Answer: (c)C.

A and C only

Why this answer is correct

The Correct answer is: A and C

Key Points

  • James Hutton demonstrated the theory of uniformitarianism in landform evolution:
  • This statement is correct.
  • James Hutton introduced the concept of uniformitarianism, which proposed that geological processes observed today have been shaping the Earth over time.
  • This concept laid the foundation for understanding gradual and continuous landform changes, influencing both Darwin and later geographers.
  • Hutton's ideas significantly impacted physical geography and theories related to the evolution of landforms.
  • Fleure used struggle and selection concept in his studies on races, states, and towns:
  • This statement is incorrect.
  • Fluere was deeply influenced by Darwinism and opined that the man-environment relationship should be studied from the physiological point of view and while delineating human regions;
  • He applies Darwin’s ideas of natural selection through environmental influence to human groups.
  • It was Taylor who investigated this idea in his studies on race, population, states, and cities.
  • Darwin's work on the origin of atolls and the idea regarding slow transformation of biological species over time inspired Davis to develop his theory of the cycle of erosion:
  • This statement is correct.
  • Darwin’s theory of evolution and his work on the transformation of atolls influenced William Morris Davis’s concept of the geographical cycle.
  • Davis used Darwin’s ideas to develop his cyclic theory, comparing landform evolution to the life cycle of an organism.
  • His work revolutionized geomorphology by emphasizing systematic changes through time.
  • Stoddart stressed the need for physiological study to assess environmental effects on man:
  • This statement is incorrect.
  • Stoddart’s contributions focused on Darwin’s key themes, such as change, organization, and struggle, but not specifically on physiological studies.
  • His analysis of Darwin’s impact on geography did not emphasize human physiological adaptations to the environment.

Additional Information

  • Darwin’s influence on geography:
  • Darwin's evolutionary ideas introduced concepts of gradual change, interdependence, and adaptation in geographical studies.
  • His impact is most notable in geomorphology, human geography, and ecological studies.
  • The ideas of struggle and selection were also incorporated into political and human geography, particularly in theories of state growth and cultural adaptation.
  • Key Contributions:
  • Influence on the development of the geographical cycle by William Morris Davis.
  • Incorporation of ecological and evolutionary concepts in studying human-environment interactions.

Question 40

Which of the follwing statements are correct?

A. Davisian model of cycle of erosion envisages space-dependent series of landform development.

B. Penck’s model of geographical cycle envisages time independent series of landform development.

C. Davisian geographical cycle over emphasized stage and gave less attention to structure.

D. Penck emphasized that geomorphic forms are expressions of phase and rate of upliftment in relation to rate of degradation.

Correct answer

Answer: (a)A.

B, C and D only

Why this answer is correct

B, C and D only

 

 Key Points

  • B (Penck's model of geographical cycle envisages time independent series of landform development): Penck proposed a model that focused on the upliftment rates of landforms and how these rates influenced the geomorphic processes independent of time. Unlike the Davisian model, which is sequential and time-dependent, Penck's model does not follow a strict chronological order in the development of landforms.
  • C (Davisian geographical cycle over emphasized stage and gave less attention to structure): The Davisian model, proposed by William Morris Davis, suggests a sequential cycle of erosion that landscapes go through, starting from youth through maturity to old age. This model heavily focuses on the stages of development and less on the geological structure, which plays a significant role in the development of landforms.
  • D (Penck emphasized that geomorphic forms are expressions of phase and rate of upliftment in relation to rate of degradation): Penck's theory emphasizes the importance of tectonic uplift and its balance with erosion. According to Penck, the geomorphic forms are a result of the interaction between the rate of uplift and the rate of erosion, rather than just the sequential stages of erosion.

Question 41

Consider the following statements related to transport, agricultural and mineral resources in India.

A. Konkan railway connects Roha to Kanyakumari and track measures 760 km.

B. Pradhan Mantri Gram Sadak Yojana provides single all weather road connectivity to the habitation of 1000 persons or more.

  4. DOption (d)

    C and D only

View answer & explanation

Correct answer

Answer: (d)D.

C and D only

Why this answer is correct

Correct Answer: C and D only

Key PointsC. Maharashtra has a longer crushing period of sugarcane than Uttar Pradesh: This is true. Maharashtra typically has a longer crushing season due to its climatic conditions, which allow for a more extended period of harvesting and crushing of sugarcane compared to Uttar Pradesh. This difference affects the overall production cycle and efficiency of sugar factories in these regions.

D . Andhra Pradesh with the share of more than 98% of total production of mica is the leading mica producing state in India: Overall, India ranks 8th among the major producers of mica in the world, with Andhra Pradesh being the largest mica-producing state with an estimated production of 7626 tonnes in 2013–14, followed by Rajasthan (6635 tonnes) and Bihar (3381 tonnes).

Additional Information 

A. Konkan Railway: The Konkan Railway indeed connects Roha in Maharashtra to Mangalore in Karnataka and is an engineering marvel due to the challenging terrain it covers, including the Western Ghats. However, it does not extend all the way to Kanyakumari, and its length is approximately 741 km, not 760 km. Therefore, this statement is partially incorrect due to the inaccuracies in the endpoints and the exact length.

B. Pradhan Mantri Gram Sadak Yojana (PMGSY): This Indian government initiative was launched to provide good all-weather road connectivity to unconnected villages. Over time, the eligibility criteria have evolved. Initially, it aimed to connect habitations of 500 persons (in plain areas) and 250 persons (in hill states, tribal and desert areas) to all-weather roads. Later amendments have focused on allowing for upgrades and enhancements in connectivity, but the basic premise of the statement simplifies the nuanced eligibility criteria. Therefore, the statement as given oversimplifies the criteria but captures the spirit of PMGSY aiming to enhance connectivity in rural areas.

Question 42

Consider the following statements regarding transportation and irrigation in India.

A. Sirhind canal originates from Satluj river to supply water for irrigation in Rajasthan.

B. Kerala state is bestowed with highest length of roads Km per 100 sq.km area among all states of India.

C. Buckingham canal is the part of National Waterway No.5 of India.

View answer & explanation

Correct answer

Answer: (d)D.

B and D only

Why this answer is correct

Correct Statements: B and D

Key Points

B. Kerala's Road Length per 100 sq.km Area: Kerala, being a smaller state with a high population density, has an extensive road network to cater to its population. However, claiming it has the highest length of roads per 100 sq.km among all states in India might be contested by other smaller or similarly dense states. As of my last update, exact rankings can fluctuate over time due to ongoing developments in infrastructure, but Kerala is known for its substantial road density due to geographical constraints and developmental policies. Detailed and current statistics would be required to confirm its position definitively.

D. Tubewells for Irrigation: Tubewells are indeed a crucial mode of irrigation in India, especially in the northern plains states like Punjab, Haryana, and Uttar Pradesh. They do provide water to a large cultivated area, and in some assessments, this form of irrigation caters to a significant portion of the irrigated area, competing closely with or surpassing surface water sources in some regions.

Additional Information

A. Sirhind Canal:  The Sirhind Canal does indeed originate from the Sutlej River, but it primarily supplies water for irrigation to Punjab and Haryana, rather than Rajasthan. While it does have branches and extensions that can support areas on the way to or near Rajasthan, the primary statement as it stands has specificity issues regarding its main irrigation areas.

C. Buckingham Canal and National Waterway No.5: The Buckingham Canal is indeed a significant waterway in India, but it is not part of National Waterway No.5. National Waterway No.5 is planned to cover certain parts of Odisha and West Bengal. In contrast, the Buckingham Canal runs through Andhra Pradesh and Tamil Nadu, making it part of the differently classified waterways.

Why this answer is correct

The correct answer is: A - III, B - I, C - IV, D - II.

Key Points

  • Concept of Primarrumpf:
  • Definition: Primarrumpf refers to the theoretical early stages of landform development. It is an idealized concept of a landscape prior to any significant erosion or dissection by water, shaped under initial climatic conditions.
  • Scholar: This concept is associated with W. Penck, who made substantial contributions to geomorphology, particularly in the context of landform evolution over time.
  • Pediplain:
  • Definition: A pediplain is a large, flat landform created by the continuous erosion of mountain slopes, which leads to the formation of a broad, gently sloping surface.
  • Scholar: This concept is most closely linked to L.C. King, who proposed the idea in relation to the process of pedimentation, which results in the creation of pediplains through weathering and erosion.
  • Panplane:
  • Definition: A panplane is an extensive, almost flat area created by the combined processes of erosion and deposition, where the landscape is typically formed in arid or semi-arid regions.
  • Scholar: This concept is primarily associated with C.H. Crickmay, who studied landforms in arid climates and explained how pans (depressions) could form as part of the larger panplain system.
  • Peneplain:
  • Definition: A peneplain is a landform that has been heavily eroded to a near-flat surface, representing the final stage of erosion in a landscape after significant geological time.
  • Scholar: The concept of peneplain is closely linked with W.M. Davis, who developed the cycle of erosion theory and identified the peneplain as a stage of landscape development after prolonged weathering and erosion.

Additional Information 

  • W.M. Davis - Cycle of Erosion:
  • Overview: W.M. Davis's Cycle of Erosion theory proposes that landscapes undergo a series of stages: youth, maturity, and old age, eventually leading to the formation of a peneplain. This idea shaped much of early geomorphological thought.
  • Importance: The theory helps explain how landforms evolve over time due to processes like weathering, erosion, and deposition, guiding the study of surface processes in physical geography.
  • C.H. Crickmay - Arid Landforms:
  • Overview: C.H. Crickmay contributed to the understanding of landforms in arid and semi-arid regions, particularly focusing on the processes of panformation and the development of panplains.
  • Importance: His work on panplains contributes to understanding how regions with limited rainfall and occasional flooding undergo significant surface alterations over time.
  • L.C. King - Pedimentation:
  • Overview: L.C. King is recognized for his work on pedimentation, which refers to the process of erosion that leads to the formation of pediplains.
  • Importance: His ideas helped shape geomorphology by explaining the relationship between surface weathering and the creation of flat, eroded plains in mountain ranges.
  • W. Penck - Theory of Geomorphology:
  • Overview: W. Penck's theory of landform development emphasized the importance of tectonic forces and climate in shaping landscapes, especially in areas undergoing uplift and erosion.
  • Importance: His work focused on the concept of primarrumpf, which describes the theoretical original state of landforms before significant erosion and weathering occurred.

<br>

Key Points 

  • Crop-combination analysis by Weaver J.C: This method was developed to identify the dominant crops of a region and to understand the agricultural economy. Weaver's approach helps in classifying agricultural regions based on their crop combinations.
  • Isolated State by von Thunen: Johann Heinrich von Thunen's model of the isolated state is one of the earliest theories of agricultural location. It describes how agricultural land use patterns are determined by the cost of transportation and the value of the land.
  • Intervening opportunities by Stouffer: Samuel Stouffer's concept of intervening opportunities is crucial in understanding migration patterns and urban development. It suggests that the number of people moving to a destination is directly affected by the presence of closer opportunities.
  • Sequent Occupance by Whittlesey, D: Derwent Whittlesey's concept of sequent occupance explains how different groups of people occupying the same area over time leave their cultural imprints on the landscape, leading to a layered composition of cultural features.

Tidal theories have evolved over time to explain the complex phenomenon of tides on Earth.

Key PointsDifferent scientists have contributed to our understanding through various theories:

  • A . Dynamic theory of tides: This theory was developed further by Pierre-Simon Laplace, who improved upon the earlier work by incorporating the dynamics of fluid motion under the influence of gravitational forces. So, A matches with III (Laplace).
  • B. Stationary wave theory of tides: This is associated with the concept that tides can be modeled as standing waves, which are a combination of two waves of the same frequency traveling in opposite directions. The closest match in the given options based on the progression of tidal theory and its contributors would be R. A. Harris, who made significant contributions to the study of tides.
  • C. Progressive wave theory of tides: William Whewell contributed to the early study of tidal phenomena through the coining of terms and organizing tidal research rather than developing this specific theory.
  • D. Equilibrium theory of tides: This theory, proposed by Isaac Newton, describes tides as the result of the gravitational pull of the Moon and the Sun on Earth's oceans, assuming the Earth is covered entirely by water and responding instantly to gravitational forces.

Key Points

A. Dardic: This is a subgroup of the Indo-Aryan languages, itself part of the larger Indo-European family. The Dardic languages are spoken in the northern regions of South Asia, including parts of India and Pakistan.

III. Shina: Shina is indeed a Dardic language, spoken in parts of Pakistan and India. So, A matches with III.

B. Mon-Khmer: This is a major branch of the Austroasiatic language family. The Mon-Khmer languages are spoken in Southeast Asia.

I. Khasi: Khasi is part of the Austroasiatic language family, specifically within the Mon-Khmer branch, primarily spoken in the Meghalaya state in India. Therefore, B matches with I.

C. North Dravidian: This is a subgroup within the Dravidian language family, which is primarily spoken in South Asia.

IV. Gondi: Gondi belongs to the Central Dravidian subgroup, not North Dravidian, but for the purpose of this match and given the options, it's understood to be within a larger Dravidian context. Given the options and context, C matching with IV seems to indicate a broader association, as Gondi is indeed a Dravidian language, albeit not "North Dravidian" by strict classification.

D. Austric: This is a proposed macro-family that, among other languages, is suggested to include the Austroasiatic languages (to which Mon-Khmer belongs). The concept of the Austric language family is not universally accepted among linguists, but it serves as an umbrella term in this context.

II. Munda: Munda languages are part of the Austroasiatic family, specifically within its own branch, separate from Mon-Khmer. Given the broad "Austric" category here, D matching with II is applied in a generalized sense, acknowledging Munda's position within a conceptually broader but debated Austric grouping.

Therefore, the correct answer based on the most accurate matchings is: Option 1) A - III, B - I, C - IV, D - II

Why this answer is correct

A - I, B - II, C - III, D - IV 

Key Points

  • A. Bores - It is the North wind, known for being cold and bringing clear skies.
  • B. Eurus - The East wind, associated in some accounts with warmth. However, descriptions of Eurus can vary, as classical sources are not always consistent. For our purposes, the closest match considering traditional attributes would be: East wind, warm and gentle.
  • C. Notus - Representing the South wind, described often as bringer of the late summer and autumn storms, and thus associated with wet and sometimes violent weather. Therefore, it matches: South wind, wet and sometimes violent.
  • D. Zephyrus - Known as the West wind, Zephyrus is often described positively, associated with gentle spring and early summer breezes. Thus, it's best matched with a description implying a more benign nature: West wind, dreaded, balmy with gale force.

Read the following passage carefully and answer questions:

Thomas Malthus was an English clergyman who, in 1798, published an Essay on the Principles of Population in which he put forward the view that, "the power of population is indefinitely greater than the power of the earth to produce subsistence for man." He thought that a balance could only be maintained if famine, disease or war periodically increased the death rate and reduced population growth. His pessimistic ideas were accepted by several other 19th century scholars in England and France. At the end of the 19th century, the population of England was only about 10 million, but much of their food supply had to be produced from the limited agricultural land of the country. Changes in land tenure, brought about by enclosure of the old common fields and the formation of large farms in the place of small scattered plots led to rural depopulation. The towns, especially those where the new factory industries had been established, grew very rapidly and were overcrowded, dirty and unhealthy. The people who lived in them were poor, under-fed, overworked and had little resistance to disease. Thus, had food supply been reduced or population expanded too rapidly, these people would have suffered starvation and epidemics would have reduced the population. This has already happened twice during England's history; the Black Death of fourteenth century and the Great Plague of the seventeenth century coincided with periods when harvest was bad and there were food shortages. Hunger reduced resistance to diseases and bubonic plague caused the death of many thousands of people. Malthus was afraid that something similar would happen again. In his time, great advances were being made in the treatment and control of diseases such as cholera, typhoid and smallpox which were still rife in England and Europe. This meant that death rates, and particularly infant mortality rates, were falling. Malthus calculated that population could double every twenty-five years, but no similar increases in food supplies could be expected.He could not have foreseen the tremendous changes which were to take place in the nineteenth and twentieth century.

Question 52

According to Malthus, what is the relationship between population growth and earth's resources?  

  1. AOption (a)

    Population grows rapidly as compared to subsistence produced from earth. 

  2. BOption (b)

    Population growth is not related with earth's resources.  

  3. COption (c)

    Population growth may be checked by famine, disease or war.  

  4. DOption (d)

    Population doubles every 25 years.

View answer & explanation

Correct answer

Answer: (a)A.

Population grows rapidly as compared to subsistence produced from earth. 

Why this answer is correct

The correct answer is Population grows rapidly compared to subsistence produced from earth.

Key Points

  • The passage explicitly states Malthus's core belief: "The power of population is indefinitely greater than the power of the earth to produce subsistence for man."
  • This indicates that Malthus saw population growth outpacing the earth's resource production, leading to potential shortages and imbalances.
  • He further argues that famine, disease, or war are necessary checks on population growth to maintain a sustainable equilibrium.

Therefore, Population grows rapidly as compared to subsistence produced from earth aligns precisely with Malthus's perspective on the relationship between population and resources.

Question 53

Which one of the following options is considered as the best description of Malthusian perspective related to population growth and resources? 

  1. AOption (a)

    Optimistic 

  2. BOption (b)

    Neutral 

  3. COption (c)

    Pessimistic 

  4. DOption (d)

    Critical 

View answer & explanation

Correct answer

Answer: (c)C.

Pessimistic 

Why this answer is correct

The correct answer is Pessimistic

Key Points

  • The passage explicitly states Malthus's view that population growth is indefinitely greater than the earth's ability to produce resources.
  • He predicted disastrous consequences like famine, disease, and war as the population outpaces resources.
  • His overall perspective suggests a negative outlook on the potential for population growth and its impact on resource availability.

Therefore, the Malthusian perspective is best described as pessimistic due to its focus on the potential negative consequences of population growth.

Question 54

The Great Plague in England's history occured in which period? 

  1. AOption (a)

    Fourteenth century 

  2. BOption (b)

    Thirteenth century 

  3. COption (c)

    Seventeenth century

  4. DOption (d)

    Fifteenth century

View answer & explanation

Correct answer

Answer: (c)C.

Seventeenth century

Why this answer is correct

The correct answer is Seventeenth century

Key Points

  • The passage mentions that the Great Plague occurred in England along with the Black Death as historical events.
  • It specifically states that the Great Plague occurred in the "seventeenth century".
  • While the Black Death is mentioned as occurring in the "fourteenth century", the question focuses on the Great Plague and its period

Question 55

What factor(s) was/were responsible for the deaths of people during Black Death and Great Plague in England? 

  1. AOption (a)

    Starvation 

  2. BOption (b)

    Plague 

  3. COption (c)

    Poor medical infrastructure 

  4. DOption (d)

    Starvation and Plague 

View answer & explanation

Correct answer

Answer: (d)D.

Starvation and Plague 

Why this answer is correct

The correct answer is Starvation and Plague 

Key Points

  • The passage clearly states that bubonic plague caused the death of many thousands of people during both the Black Death and the Great Plague.
  • It mentions that hunger reduced resistance to diseases further exacerbating the impact of the plague.
  • While poor medical infrastructure likely contributed to some deaths, the passage emphasizes the primary role of plague and the compounding effect of starvation.

Question 56

Improvement in the treatment and control of diseases in England and Europe helped to substantially reduce mortality in which age group of the population? 

  1. AOption (a)

    Adult population 

  2. BOption (b)

    Infant population 

  3. COption (c)

    Older population 

  4. DOption (d)

    Older children 

View answer & explanation

Correct answer

Answer: (b)B.

Infant population 

Why this answer is correct

The correct answer is Infant population.

Key Points

  • The passage explicitly states that improvements in disease treatment and control led to a decline in death rates, particularly infant mortality rates.
  • This suggests that the advances in healthcare primarily benefited the infant population, who were previously more vulnerable to diseases like cholera, typhoid, and smallpox.
  • While overall mortality rates likely declined across all age groups, the passage emphasizes the specific impact on infant mortality,

Question 57

Who stated that valley side slope gives a clue to the relative importance of exogenic and endogenic processes? 

  1. AOption (a)

    Davis

  2. BOption (b)

    Penck

  3. COption (c)

    King

  4. DOption (d)

    Gilbert

View answer & explanation

Correct answer

Answer: (b)B.

Penck

Why this answer is correct

The correct answer is Penck

Key Point

  • Walther Penck stated that valley side slope provides insight into the relative importance of exogenic (external, such as weathering and erosion) and endogenic (internal, such as tectonic uplift) processes.
  • Penck's model challenged previous geomorphological theories by asserting that landforms are a reflection of the balance between uplift rates and the processes of erosion. This viewpoint is summarized in the provided search results

Explanation of Incorrect Options:

  • Davis: William Morris Davis is known for the concept of the geographical cycle or the cycle of erosion, which explains the development of landscapes in terms of structure, process, and time. His model describes a sequential evolution from youthful stages through maturity to old age, focusing on how landscapes evolve under the influence of river erosion. While Davis emphasized the role of processes over time, he did not specifically state that the valley side slope is a clue to the relative importance of exogenic and endogenic processes.
  • King: Lester King was another significant geologist known for his work on geomorphology, but he is not cited for the statement in question. King conducted studies in various parts of the world and contributed to understanding the role of tectonic activities in shaping landscapes, but the specific focus on valley side slope as an indicator of the balance between exogenic and endogenic processes is not directly attributed to him in the provided information.
  • Gilbert: Grove Karl Gilbert, known for his monumental work in geomorphology, especially his studies on landscape evolution and the dynamics of erosion, did focus on the significance of processes in shaping landforms. Though he made several contributions to understanding geomorphic processes, the specific statement regarding valley side slope giving clues to the importance of exogenic versus endogenic processes is not attributed to him in the context provided.

Additional Information

  • Penck's theory emphasizes the interaction between uplift (endogenic processes) and erosion (exogenic processes).
  • He proposed that the landscape's current form could not be solely understood through the lens of erosion without considering the ongoing uplift.
  • For Penck, the rate of uplift in comparison to the rate of erosion gives valleys their shapes and sizes, which in turn indicates the dominant processes at work.
  • He highlighted that in areas of rapid uplift, valleys would be deep and steep-sided, whereas in areas of slower uplift or dominant erosion, valleys might be wider and less steep.
  • This approach introduced a more dynamic relationship between the processes shaping the Earth's surface, moving beyond the more staged approach of Davis's cycle of erosion.

Question 58

Which of the following is not directly related to magnitude of earthquake?  

  1. AOption (a)

    Length of fault section that broke 

  2. BOption (b)

    Damage severity  

  3. COption (c)

    Depth of focus 

  4. DOption (d)

    Amount of energy released by earthquake. 

View answer & explanation

Correct answer

Answer: (b)B.

Damage severity  

Why this answer is correct

The correct answer is Damage severity.

Key Points

  • The magnitude of an earthquake is a measure of the amount of energy released during the earthquake. It is determined by the length of the fault section that broke and the amount of slip along the fault. The depth of the focus of the earthquake also affects the magnitude but to a lesser extent.
  • Damage severity, on the other hand, is a measure of the physical damage caused by the earthquake. It is influenced by some factors, including the magnitude of the earthquake, the distance from the earthquake epicenter, the local geology, and the type of buildings and infrastructure.

Key Points

  • The primary ingredient of photochemical smog is ozone (O₃). It is a gas molecule made up of three oxygen atoms. Ozone is naturally occurring in the Earth's atmosphere, but it can also be formed by chemical reactions between nitrogen oxides (NOx) and volatile organic compounds (VOCs) in the presence of sunlight.
  • Carbon dioxide (CO2) is a colorless, odorless gas with a slightly sour taste. It is a naturally occurring greenhouse gas that is essential for life on Earth. Plants use carbon dioxide to photosynthesize, converting it into oxygen and energy. However, human activities, such as burning fossil fuels, deforestation, and industrial processes, have increased the concentration of carbon dioxide in the atmosphere. This has led to global warming and other climate change effects

  • Over the equator: The tropopause reaches its maximum height, which is typically around 16-18 km

Question 61

Which one of the following measure represents perhaps the most sensitive barometer of the fitness of the social environment for human life? 

  1. AOption (a)

    Maternal Mortality Ratio 

  2. BOption (b)

    Crude death rate 

  3. COption (c)

    Child mortality rate 

  4. DOption (d)

    Infant mortality rate 

View answer & explanation

Correct answer

Answer: (d)D.

Infant mortality rate 

Why this answer is correct

Infant mortality rate 

Key Points

  • The infant mortality rate, the number of deaths of infants under one year old per 1,000 live births, is widely considered a critical indicator of the overall health and well-being of a population.
  • It reflects the effectiveness of healthcare systems, the level of nutrition, the quality of sanitation and access to clean water, and the general socioeconomic conditions of a society.
  • Because infants are the most vulnerable members of any population, their survival and health are directly influenced by the quality of the social, economic, and environmental conditions they are born into.
  • Consequently, improvements or declines in the infant mortality rate can serve as a sensitive signal of changes in the fitness of the social environment for human life

 Additional Information

Maternal Mortality Ratio

  • This measure is an indicator of the health and safety conditions that women face during pregnancy and childbirth.
  • It reflects the effectiveness of healthcare systems, the accessibility of healthcare, and the overall socio-economic conditions that affect women's health.
  • A high maternal mortality ratio indicates serious gaps in the healthcare system, issues with access to healthcare, and possibly cultural or societal norms that prevent women from receiving the care they need.
  • It is considered a sensitive barometer for the fitness of the social environment for human life because it directly correlates to how societies prioritize and manage women's health, which has far-reaching implications on family health and societal well-being.

 

Crude Death Rate:

    • This measures the total number of deaths per year per 1,000 people in a population. While it provides an overall view of the mortality within a population, it does not specifically highlight the conditions of vulnerable groups like women during childbirth or infants.
  • It is less sensitive as a barometer for the fitness of the social environment because it is influenced by a broad range of factors, including age distribution and specific causes of death that may not directly relate to the social or healthcare environment.
<br>

Child Mortality Rate:

    • Indicates the number of deaths of children under the age of five. While this is a critical indicator of public health, nutrition, and healthcare access, it is slightly less specific than the maternal mortality ratio in reflecting the direct impact of the social environment on vulnerable populations.
  • It encompasses a wider range of factors, including infectious diseases, nutrition, and accidents, which might not solely relate to the social environment's fitness.

Question 62

Who among the following first used the term Ecumene and Non-ecumene to distinguish between inhabited and unhabited portion of earth's surface?  

  1. AOption (a)

    Romans 

  2. BOption (b)

    Greeks

  3. COption (c)

    German

  4. DOption (d)

    French

View answer & explanation

Correct answer

Answer: (b)B.

Greeks

Why this answer is correct

Correct Answer: Greeks

 Key Points

  • The term "Ecumene" refers to the inhabited portion of the Earth as known to the ancient Greeks, while "Non-ecumene" refers to the uninhabited or unknown parts.
  • The concept was used to distinguish between the areas of the Earth's surface that were known and populated by humans and those that were not.
  • This distinction reflects the geographical knowledge and exploratory reach of ancient civilizations, particularly the Greeks, who were pioneers in the field of geography and made significant contributions to mapping and understanding the world as they knew it.

Additional Information 

  • Romans: Although the Romans were excellent engineers and made significant contributions to urban planning and the development of infrastructure, the specific terms "Ecumene" and "Non-ecumene" are attributed to the Greeks. The Romans did expand on Greek geographical knowledge but did not originally coin these terms.
  • German: Germanic peoples and scholars have contributed significantly to various fields, including geography, in later periods. However, the specific concepts of Ecumene and Non-ecumene as terms originate from ancient Greek civilization, not German.
  • French: Like the Germans, the French have a rich history of contributions to science, including geography, in the modern era. However, the distinction between inhabited and uninhabited parts of the Earth using the terms Ecumene and Non-ecumene was first made by the Greeks, predating French contributions to the field.
<br>

Hence, The Greeks' use of these terms underscores their role as early pioneers in the systematic study of the Earth and its various regions, laying the groundwork for future geographical and cartographical advancements.

  3. COption (c)

    E. A. Jones

  4. DOption (d)

    W. Zelinsky

View answer & explanation

Correct answer

Answer: (b)B.

G. T. Trewartha

Why this answer is correct

G. T. Trewartha

Key Points

  • Glenn Thomas Trewartha was an American geographer who made significant contributions to the field of population geography.
  • His work, including the statement quoted, emphasizes the central role of population studies in understanding geographical phenomena, patterns, and processes.
  • Trewartha's perspective underscores the idea that the study of human populations— their distribution, density, composition, and growth trends—provides essential insights into the broader physical and human geography
<br>

Additional Information

  • J. I. Clarke famously stated that undefined population is the point of reference from which all other elements are observed and derive significance and meaning. undefined Clarke's work has been influential in understanding the role of population in geographical and social analysis, emphasizing the centrality of human populations in interpreting landscapes, economic activities, and social structures.
    • E. A. Jones is less widely cited in the context of this specific statement about population. Jones's work may cover various aspects of geography or related disciplines, but he is not primarily associated with the idea that population is the foundational element in geographical analysis.
    • W. Zelinsky is best known for his work on the mobility transition model, which describes the relationship between the demographic transition and the changes in migration patterns. While his work emphasizes the importance of population dynamics, it does not specifically focus on population as the central point of reference in the way described in the statement.

Question 64

Which of the following does not represent functions of the town? 

  1. AOption (a)

    Culture and recreation 

  2. BOption (b)

    Transportation 

  3. COption (c)

    Fishing and farming 

  4. DOption (d)

    Resource Extraction  

View answer & explanation

Correct answer

Answer: (c)C.

Fishing and farming 

Why this answer is correct

Fishing and farming 

Key Points

  • Fishing and farming are primarily rural activities focused on utilizing natural resources directly from the environment for food production.
  • Towns, especially those that are more urbanized, typically serve as centers for processing, marketing, and distributing agricultural products rather than being primary locations for fishing and farming activities.
  • Urban areas are more associated with higher-level services, manufacturing, and other non-agricultural economic activities due to their population density, infrastructural development, and market dynamics.

 

Explanation of Incorrect Options:

  • Culture and recreation: Towns often serve as important centers for cultural activities and recreation. They provide venues for social interaction, entertainment, and cultural expression, such as theaters, museums, parks, and community centers. These functions are vital for the quality of life of residents and attract visitors, contributing to the local economy.
  • Transportation: Towns function as key nodes in transportation networks, facilitating the movement of people and goods. They may have bus and train stations, and sometimes airports, connecting them with other towns, cities, and regions. The transportation infrastructure supports economic activities and access to services, making transportation a crucial function of towns.
  • Resource Extraction: While resource extraction might seem primarily associated with rural or remote areas, towns can also function as bases for such activities. This is especially the case when they act as service and administrative centers for industries like mining, quarrying, or oil extraction. These towns provide logistical, administrative, and support services for resource extraction activities, although the actual extraction sites might be located in the surrounding areas rather than within the town itself.

 Additional Information

  • The functions of a town evolve from its historical, geographic, and economic context.
  • While fishing and farming are fundamental to human settlement and survival, the role of towns has expanded significantly with urbanization and economic development.
  • Modern towns and cities encompass a wide range of functions beyond the primary production of goods, including a strong emphasis on services, administration, and knowledge-based industries.
  • This diversification reflects changes in technology, transportation, and societal needs, leading to complex urban functions that support both the local population and broader economic systems.

Correct answer

Answer: (d)D.

C and D only

Why this answer is correct

The correct answer is C and D only.

Key Points

  • Spatial interaction is reflected in the flow of people, goods and information: Correct.
  • Spatial interaction refers to the movement and flows involving human activities, goods, information, and services between different locations.
  • It encompasses all processes related to the spatial distribution of human activities and their manifestations.
  • Gravity model is used for spatial interaction analysis: Correct.
  • The gravity model is a widely used model in geography for predicting and understanding spatial interaction between any two places based on their size and distance.
  • The model is analogous to Newton's law of gravitation in physics.
  • Hurst applied concepts of conduction, convection and radiation of physics in his model of spatial interaction: Incorrect.
  • Hurst did not apply the concepts of conduction, convection, and radiation in his model of spatial interaction.
  • These concepts are generally used in thermodynamics and fluid dynamics, not typically in spatial interaction models in geography.
  • The direction of spatial interaction is determined exclusively by intervening opportunities: Incorrect.
  • While intervening opportunities are a factor that can influence the direction of spatial interaction, they are not the only determinant.
  • Other factors such as distance, accessibility, economic conditions, and cultural ties also play significant roles.

Additional Information

  • Spatial Interaction Models:
  • There are several models used to study spatial interaction, including the Gravity Model, the Potential Model, and the Huff Model.
  • These models account for various factors such as distance, population size, and the presence of intervening opportunities.

Question 66

Which of the following statements are correct with reference to Weber's Industrial location theory?

A. It is based on the assumption of variable physical and cultural landscape.

B. Entrepreneurs have perfect knowledge of location of raw material and the market.

C. Agglomeration has no role in determining industrial location.

D. There are multiple modes of transportation.

  1. AOption (a)

    B and E only

  2. BOption (b)

    A, B and E only

  3. COption (c)

    C, D and E only

  4. DOption (d)

    B, C and D only

View answer & explanation

Correct answer

Answer: (a)A.

B and E only

Why this answer is correct

B and E only

Alfred Weber's Industrial Location Theory, introduced in 1909, is a framework designed to predict and explain the location of industries at a macro-scale. It revolves around minimizing the costs of transportation, labor, and agglomeration as the primary determinants of industrial location. 

Key Points

A. It is based on the assumption of variable physical and cultural landscape: This statement does not directly relate to the core of Weber’s theory, which focuses more on cost minimization (especially transportation and labor) rather than the variability of the physical and cultural landscape. Weber's theory does consider raw material locations and market locations, which could be influenced by physical and cultural landscapes, but the statement as worded could be misleading regarding the theory’s foundation. 

B. Entrepreneurs have perfect knowledge of location of raw material and the market: This is correct. Weber's theory assumes that entrepreneurs possess full information about the distribution of raw materials and markets to minimize transportation costs.

C. Agglomeration has no role in determining industrial location: This statement is incorrect. Agglomeration, or the clustering of industries, plays a significant role in Weber’s theory. The benefits of agglomerated industries can outweigh the transportation costs, influencing entrepreneurs to locate their businesses near each other to take advantage of shared services, labor markets, and infrastructures.

D. There are multiple modes of transportation: While Weber's theory does consider transportation costs as crucial, it doesn't explicitly focus on the variety of transportation modes in its original form. It's primarily about minimizing transportation costs, whether that involves different modes of transportation may be considered an extension or application of the theory rather than its foundational premise.

E. It is based on principle of least- cost location: This is correct. The core principle of Weber’s theory is finding the least-cost location which minimally involves minimizing transportation costs but also factors in labor costs and agglomeration economies to determine the optimal industrial location.

Hence, Option 1) B and E only: This is the correct answer since these statements accurately reflect key components of Weber's Industrial Location Theory — that entrepreneurs have perfect knowledge of raw materials and market locations (B) and that the theory is fundamentally about finding the least-cost location (E).

Question 67

Identify the correct sequence of the concentric zones of different land uses from the city center in Von Thunen's model?

    C, D, B, A, E

  3. COption (c)

    C, B, A, D, E

  4. DOption (d)

    C, D, E, B, A

View answer & explanation

Correct answer

Answer: (c)C.

C, B, A, D, E

Why this answer is correct

C, B, A, D, E

The Von Thünen model, developed by Johann Heinrich von Thünen in the early 19th century, attempts to explain and predict agricultural land use patterns in a theoretical state by varying transport costs associated with distance from a central city. According to this model, different types of land use are arranged in concentric rings around the central city, each defined by the cost of transportation and the value of the produce, which in turn depends on the perishability of the goods and the technology available for farming and transport.

Key PointsHere's how the Von Thünen model organizes land use, starting from the city center outwards:

  • Market Gardening and Milk Production (C): This zone is closest to the city because these products are perishable and need to be delivered quickly to the market.
  • Firewood and Timber (B): Before the industrial revolution and the widespread use of coal, wood was a primary fuel for heating and cooking and a material for construction, so this zone came after perishable products due to its bulk and weight.
  • Crop Farming without Fallow (A) / Three-Field System (D): These zones represent areas of extensive field cropping, with "A" being intensive farming that could include high-yield crops farmed continuously without leaving the land fallow, and
  • "D" possibly representing a more traditional method of crop rotation including fallow land. These zones' placement may vary depending on specific interpretations of the model, but both represent areas where crops are grown.
  • Livestock Ranching (E): This zone is the furthest from the city. Livestock can be raised far from the market because they’re self-transporting to a degree, and land costs are lower at these distances from the city, making it economic to raise animals there.
  • Given this information, the correct sequence that matches Von Thünen's model from the city center outward is closer to:

Option 3) C, B, A, D, E

  • C. Market gardening and milk production
  • B. Firewood and timber
  • A. Crop farming without fallow
  • D. Three-field system
  • E. Livestock ranching

Answer: (d)D.

C, B, D, A

Why this answer is correct

C, B, D, A

Key Points

The Human Development Index (HDI) is a composite statistic used to rank countries by level of "human development." It considers factors such as life expectancy, education, and per capita income indicators, offering a snapshot of a country's average achievements in these areas. Countries are classified into four tiers of human development on the basis of their HDI scores: very high, high, medium, and low human development.

  • According to the Human Development Index (HDI) -:

Country            HDI            Rank  

Switzerland      .967                1

Norway            .966                2

Iceland            .959                 3

Australia          .946                10

  • HDI is an Index which is used to measure a country's development by United Nations Development Programme (UNDP).
  • As per the above table highest HDI valued country ranks 1 and so on.
  • Hence option ( 4 ) i.e.  Switzerland, 'Norway, Iceland, Australia, ' is correct.
  • HDI is scored by using three indexes i.e. : Gross National Income. Health. Education.

Additional Information 

  • The HDI is published annually by the United Nations Development Programme (UNDP) and is used as a means of assessing and comparing the prosperity, health, and education of countries around the globe.
  • Its comprehensive approach to measuring well-being and development progress makes it a valuable tool for policymakers and researchers.
  • The index aims not only to evaluate the economic aspect of a country's development but also to emphasize the importance of people's ability to lead a long and healthy life, acquire knowledge, and have a decent standard of living.

Why this answer is correct

The correct option is: option 2) A, B, D, C

Key Points

  • A , B, D, C - The arrangement of the longitudinal fault lines in the Himalayas from south to north is: Himalayan Frontal Fault (HFF), Main Boundary Thrust (MBT), Main Central Thrust (MCT), and Indus-Tsang Po Suture Zone (ITSZ).
  • Himalayan Frontal Fault (HFF), also known as Main Frontal Thrust (MFT), is the southernmost major fault, delineating the boundary between the Himalayas and the Indo-Gangetic Plain.
  • Main Boundary Thrust (MBT) lies north of the HFF/MFT and is another significant fault that marks a major geological boundary within the Himalayan region.
  • Main Central Thrust (MCT) is further north of MBT and is a critical geological structure within the High Himalayas, responsible for much of the region's high-grade metamorphism and structural complexities.
  • Indus-Tsang Po Suture Zone (ITSZ) is the northernmost, marking the boundary between the Asian Plate and the subducted Indian Plate. It represents the original collision zone between India and Asia.
  • The progression from south to north (A, B, D, C) reflects the general order of these fault systems as one moves from the foreland basin (Indo-Gangetic Plain) into the higher elevations of the Himalaya and towards the Tibetan Plateau.

Additional Information 

  • The arrangement of these fault structures follows a general south-to-north transition from relatively lower-grade metamorphic and tectonic structures to the high-grade metamorphic belts and the main collision boundary between continental plates.
  • These fault systems are crucial for understanding the tectonic evolution, seismicity, and mountain-building processes in the Himalayan region.
  • The progression reflects the complex tectonic interactions that have shaped the Himalayas over millions of years, including the ongoing convergence between the Indian Plate and the Eurasian Plate.

Question 70

Given below are two statements:

Statement I: Maximum salinity is seen at Tropic of Cancer and the reason may be low rainfall, high evaporation and high atmospheric pressure.

Statement Il: Minimum salinity is seen in temperate zone because of excess of evaporation and larger supplies of fresh water.

In light of the above statements, choose the correct answer from the options given below:

  1. AOption (a)

    Both Statement I and Statement Il are true. 

  2. BOption (b)

    Both Statement I and Statement II are false. 

  3. COption (c)

    Statement I is true but Statement II is false. 

  4. DOption (d)

    Statement I is false but Statement II is true. 

View answer & explanation

Correct answer

Answer: (c)C.

Statement I is true but Statement II is false. 

Why this answer is correct

The correct answer is option 3) Statement I is true but Statement II is false.

Key Points

Statement I: This statement is true.

  • Maximum salinity is often observed in regions near the Tropic of Cancer (and Tropic of Capricorn), where conditions like low rainfall, high evaporation, and high atmospheric pressure prevail.
  • These conditions lead to more water evaporating than is being replenished by precipitation, which concentrates the salts and minerals in the water, thereby increasing salinity.
  • The Red Sea and the Persian Gulf are examples of regions with very high salinity due to such conditions.

 

Statement II: This statement is false.

  • The minimum salinity is not seen in temperate zones because of excess evaporation and larger supplies of fresh water.
  • In reality, minimum salinity is often observed in higher latitudes and temperate zones due to lower temperatures which reduce evaporation rates, and because of the input of large volumes of fresh water from rivers and precipitation, especially in areas near river mouths or coastal regions where melting ice and snow contribute to reducing salinity.
  • For example, the Baltic Sea has relatively low salinity because it receives a large influx of fresh water from surrounding rivers and has limited exchange of water with the open ocean.
  • Thus, the primary reasons for minimum salinity in these areas are the abundant fresh water inputs and reduced evaporation rates, not "excess of evaporation" as the statement suggests.

Question 71

Debris Avalanche 

Why this answer is correct

The correct answer is Debris Avalanche.

Key Points

  • Debris avalanches are rapid, gravity-driven flows of loose rock, soil, and vegetation down slopes. They can reach speeds of up to 100 meters per second (224 miles per hour), making them the fastest of the given options.
  • Mudflows are also rapid flows of mud and water down slopes, but they are typically slower than debris avalanches, reaching speeds of up to 10 meters per second (22 miles per hour).
  • Earthflows are slow-moving landslides that occur on gentle slopes. They typically move at a rate of millimeters to centimeters per day.
  • Solifluction is the slow downslope movement of soil due to freeze-thaw action. It is the slowest of the given options, typically moving at a rate of millimeters to centimeters per year.

Question 72

How many minimum seismic stations data is required to map the epicentre of earthquake? 

  1. AOption (a)

    One

  2. BOption (b)

    Two

  3. COption (c)

    Three

  4. DOption (d)

    Four

View answer & explanation

Correct answer

Answer: (c)C.

Three

Why this answer is correct

The correct answer is Three

Key Points

  • An earthquake is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves.
  • To determine the epicenter of an earthquake, a minimum of three seismic stations are required. Each seismic station records the arrival times of different seismic waves, such as primary (P) waves and secondary (S) waves, which travel at different speeds through the Earth's interior. By comparing the arrival times of these waves at different stations, scientists can use triangulation to locate the epicenter, which is the point on the Earth's surface directly above the earthquake's origin.

Additional Information

  • Types of Earthquakes
    • Tectonic earthquakes: The most common form of earthquake, is caused by the movement of loose fragmented pieces of land on the earth’s crust known as tectonic plates.
  • Volcanic earthquake: The less prevalent compared to the tectonic variety, these earthquakes happen before or after the eruption of a volcano. It is caused when magma leaving the volcano is filled by rocks being pushed to the surface.
  • Collapse earthquake: This earthquake occurs in underground mines. The main cause is the pressure generated within the rocks.
  • Explosion earthquakes: The occurrence of this type of earthquake is artificial. High-density explosion such as nuclear explosions is the primary cause.
  • Causes of Earthquakes
  • It is caused due to the tectonic movements of the earth.
  • The energy release produces waves that travel in all directions.
  • The point where energy is released is called the focus or hypocentre. It is generally located at a depth of 60 km.
  • This causes a release of energy, and the energy waves travel in all directions.
  • The point where the energy is released is called the focus of an earthquake or hypocentre.
  • The point on the surface of the earth which is vertically above the focus is called the epicentre. It is the first place to experience the waves.

Question 73

Which one of the following approaches advocates to think that the most effective philosophical ground for protecting the natural environment is to think in terms of protecting natural beauty? 

  1. AOption (a)

    Deep ecology 

  2. BOption (b)

    Enviromental pragmatism 

  3. COption (c)

    Social ecology 

  4. DOption (d)

    Environmental aesthetics  

View answer & explanation

Correct answer

Answer: (d)D.

Environmental aesthetics  

Why this answer is correct

The correct answer Environmental aesthetics 

Key Points

  • Environmental pragmatism: This approach focuses on finding practical solutions to environmental problems based on scientific evidence and economic
  • Deep ecology: While deep ecology emphasizes intrinsic values in nature and advocates for biocentrism, its main focus is not solely on protecting natural beauty. It has a more holistic approach that considers the interconnectedness of all living beings and the importance of preserving ecological balance considerations. While it may sometimes involve protecting natural beauty as a means to achieve other goals, it is not its primary philosophical ground.
  • Social ecology: This approach emphasizes the link between social and environmental problems and advocates for radical social change to achieve ecological sustainability. While it may value natural beauty, it doesn't regard it as the single most effective ground for environmental protection.
  • Environmental aesthetics: This approach argues that the beauty of nature has intrinsic value and deserves protection. It emphasizes the emotional and spiritual connection humans have with nature and believes that appreciating its beauty can inspire us to protect it.

Therefore, environmental aesthetics aligns best with the statement about protecting the natural environment based on its beauty.

Question 74

Manufacture of biomass by organisms that eat plants is termed as: 

  1. AOption (a)

    Primary productivity 

  2. BOption (b)

    Net primary productivity 

  3. COption (c)

    Secondary productivity 

  4. DOption (d)

    Tertiary productivity 

View answer & explanation

Correct answer

Answer: (c)C.

Secondary productivity 

Why this answer is correct

The correct answer is Secondary productivity.

Key Points

  • Secondary productivity refers to the biomass produced by organisms that eat plants (herbivores). They convert the energy stored in plant biomass into their biomass through consumption.
  • Primary productivity refers to the total amount of organic matter produced by plants through photosynthesis.
  • Net primary productivity (NPP) is the amount of energy left after accounting for the energy that plants use for their respiration.
  • Tertiary productivity refers to the biomass produced by organisms that eat herbivores (carnivores).

Therefore, organisms that eat plants directly contribute to secondary productivity

 Key Points B. Geography of Voting – This focuses on the spatial patterns of voting behavior. It examines how people in different locations vote, including differences across regions, urban vs. rural areas, and various demographic groups.

D. Geographic influences on Voting – This encompasses the study of how geographical factors, including physical features (like mountain ranges or rivers), settlement patterns, urbanization, and socio-economic characteristics of regions, influence voting behavior and political attitudes.

E. Geography of Representation – This focuses on how electoral systems and districting impact representation. It looks at how the drawing of electoral districts (gerrymandering, for instance) affects political representation and the fairness of electoral systems.

 Additional Information

  • Electoral geography bridges the gap between politics and geography, providing insights into the spatial dimensions of electoral processes, outcomes, and representations.
  • It helps in understanding the complex interactions between people, places, and politics, contributing to more informed electoral strategies and policies.
  • The study of electoral geography can aid in the prediction of electoral outcomes, the planning of political campaigns, and the assessment of electoral fairness and democracy.
  • By examining these aspects, researchers and policymakers can better understand the dynamics of electoral competition and the importance of geographical context in shaping electoral politics.

Question 76

Which of the following statements are NOT correct regarding the concept of growth pole?

A. Perroux’s original work focuses on the development of growth poles in economic space.

B. Boudeville comprehensively excluded the geographical dimension from growth pole.

C. The processs of polarisation depends upon agglomeration economies.

D. The trickle-down effect are of minimum interest to regional planners.

E. Spatial interactions include movement of goods only.

  2. BOption (b)

    A, C and D only

  3. COption (c)

    B, C, D and E only

  4. DOption (d)

    B, D and E only

View answer & explanation

Correct answer

Answer: (d)D.

B, D and E only

Why this answer is correct

The correct answer is option 4) B, D and E only.

Key Points

B . The statement "Boudeville comprehensively excluded the geographical dimension from growth pole" is not correct. On the contrary, Boudeville expanded on Perroux's concept by incorporating the geographical dimension into the growth pole theory. He emphasized the importance of the spatial aspect in the development of growth poles, arguing that the geographical location and the spatial distribution of industries play critical roles in economic development.

D. The claim that "The trickle-down effects are of minimum interest to regional planners" is also incorrect. The trickle-down effect, which refers to the process by which economic benefits generated in one sector or region spread to other sectors or regions of the economy, is of significant interest to regional planners. Regional planners are concerned with ensuring that the benefits of growth in growth poles or specific economic activities spread to wider areas, contributing to balanced and inclusive regional development.

E. The statement "Spatial interactions include movement of goods only" is not correct. Spatial interactions in the context of growth poles and economic geography generally encompass not only the movement of goods but also the movement of people (labour mobility), services, capital, and information. These interactions are crucial for understanding the dynamics of economic development and the diffusion of economic benefits across regions.

<br>

 A. "Perroux’s original work focuses on the development of growth poles in economic space" is a correct statement. François Perroux, a French economist, introduced the concept of growth poles (pôles de croissance) in the 1950s, focusing on sectors or industries with significant potential to drive economic development in the surrounding area. Perroux's work emphasized the concentration of industries and the creation of economic dynamism in specific "poles" within the economic space.

C. "The process of polarization depends upon agglomeration economies" is also correct. Polarization in the context of growth pole theory refers to the concentration of economic activities in certain areas, leading to regional imbalances. This process often depends on agglomeration economies, which are the benefits that firms obtain by locating close to each other. These benefits include reduced transportation costs, access to specialized labor and inputs, and knowledge spillovers, which all contribute to the phenomenon of polarization as described in growth pole theory.

 Additional Information

  • The growth pole concept is a model for economic development that suggests that specific industries or sectors within an economy can act as catalysts for growth in the surrounding area, creating a pole of economic activity.
  • This concept has been influential in regional planning and economic development strategies, emphasizing the importance of focusing resources on key sectors or regions to stimulate overall economic growth.
  • The theory acknowledges both the positive effects of economic concentration (e.g., agglomeration economies) and the potential for negative outcomes (e.g., regional disparities, polarization).

    A, B, C and E only

View answer & explanation

Correct answer

Answer: (c)C.

A, B and E only

Why this answer is correct

Correct Answer : A, B and E only

 Key Points

  • The founding members of the Organization of the Petroleum Exporting Countries (OPEC), which was established in 1960.
  • OPEC was created during the Baghdad Conference, held from September 10-14, 1960, by five oil-producing countries aiming to negotiate with oil companies over matters related to oil production, prices, and the rights of the oil-producing countries.
  • The founding members were:

A. Iran - As one of the largest oil-producing countries in the Middle East, Iran was among the founding members, seeking to have more control over its oil resources and prices on the international market.

B. Iraq - Iraq, being the host of the conference where OPEC was founded, played a crucial role in the establishment of the organization. Like Iran, Iraq sought to gain more influence over its oil production and pricing.

E. Saudi Arabia - As one of the world's leading oil exporters, Saudi Arabia's involvement was critical for the formation of OPEC. The country has retained a significant influence within the organization due to its large oil reserves and production capacity.

The other options provided are:

C. Indonesia - While Indonesia was an early member of OPEC, joining in 1962, it was not among the founding countries. Indonesia has a unique position as it was the only member from Southeast Asia and has fluctuated between being a net oil exporter and importer over the years. Indonesia even suspended its membership in 2009, rejoined in 2016, and suspended it again later.

D. Libya - Libya, another significant oil-producing country, joined OPEC shortly after its formation, in 1962, but was not a founder. Libya's membership highlighted the growing influence of OPEC among oil-producing nations beyond the initial Middle East founders.

 Additional Information

  • OPEC's main goal is to coordinate and unify petroleum policies among member countries, to secure fair and stable prices for petroleum producers, an efficient economic and regular supply of petroleum to consuming nations, and a fair return on capital to those investing in the industry.
  • Over the years, OPEC has played a significant role in setting oil prices and production levels, though its influence has been challenged by the rise of non-OPEC oil producers, changes in global energy demand, and the increasing importance of renewable energy sources.

Question 78

Identify the sequence of clouds in sky (first to last) as a warm front approaches an observer/ place in the middle latitudes.

B. Nimbostratus

C. Altostratus

D. Cirrus

Choose the correct answer from the options given below:

  1. AOption (a)

    D, A, C, B

  2. BOption (b)

    C, D, B, A

  3. COption (c)

    D, C, A, B

  4. DOption (d)

    D, B, C, A

View answer & explanation

Correct answer

Answer: (a)A.

D, A, C, B

Why this answer is correct

Correct Answer: D, A, C, B

Key Points 

As a warm front approaches an observer in the middle latitudes, the sequence of clouds observed typically follows a pattern based on their altitude and the atmospheric conditions associated with the front.

  • Cirrus (D): These are high-altitude, wispy clouds that appear first. They are made of ice crystals and signal the initial approach of a warm front. Their presence is due to the warm, moist air being lifted gradually over the cooler air mass in front.
  • Cirrostratus (A): Following cirrus clouds, cirrostratus clouds form a thin, high-altitude layer that can cover the entire sky. They often give the sky a milky appearance and can create halos around the sun or moon. These clouds indicate the front is getting closer.
  • Altostratus (C): As the front approaches further, altostratus clouds replace cirrostratus. These mid-level clouds often cover the entire sky in a gray or blue-gray color, leading to diffused sunlight or moonlight. The thickening of these clouds signals an impending precipitation.
  • Nimbostratus (B): Finally, nimbostratus clouds appear as the warm front is upon the observer. These are thick, dark clouds that cover the sky and bring continuous, steady precipitation. They are low-level clouds, although their base can sometimes extend into the middle cloud level.

    B, D, C, A

  2. BOption (b)

    C, A, D, B

  3. COption (c)

    C, D, B, A

  4. DOption (d)

    D, C, A, B

View answer & explanation

Correct answer

Answer: (b)B.

C, A, D, B

Why this answer is correct

The correct option is: option 2) C, A, D, B

Key Points

  • C . Sodium chloride (NaCl) is the most abundant salt in seawater, making up the majority of dissolved salts. It's the primary reason seawater tastes "salty."
  • A. Magnesium chloride (MgCl2) follows sodium chloride in terms of abundance but is significantly lesser in percentage compared to NaCl.
  • D. Magnesium sulphate (MgSO4) is another significant component of seawater salts, though it ranks below sodium chloride and magnesium chloride in terms of concentration.
  • B. Calcium carbonate (CaCO3), while important for marine life, especially in the formation of shells and coral structures, is present in much lower concentrations compared to the other salts mentioned, making it the least in this sequence.

 Additional Information

  • The ocean's salinity and the composition of dissolved salts result from the erosion of rocks on land, volcanic activity, and the earth's geological history.
  • Sodium chloride comes primarily from the chemical weathering of rocks, while the other salts like magnesium chloride and magnesium sulfate come from various other geological and biochemical processes.
  • Calcium carbonate's presence is significantly due to biological processes in the ocean, particularly involving marine organisms that use it to build shells and skeletons.

Question 80

Given below are two statements, one is labelled as Assertion (A) and the other is labelled as Reason (R).

Assertion (A) : El Nino has a strong effect on marine life along the Peru coast.

Reason (R) : During El Nino, upwelling of nutrient rich cold water is weakened which affects phytoplankton.

In light of the above statements, choose the correct answer from the options given below:

  1. AOption (a)

    Both (A) and (R) are true and (R) is the correct explanation of (A).  

  2. BOption (b)

    Both (A) and (R) are true but (R) is NOT the correct explanation of (A). 

  3. COption (c)

    (A) is true but (R) is false. 

  4. DOption (d)

    (A) is false but (R) is true. 

View answer & explanation

Correct answer

Answer: (a)A.

Both (A) and (R) are true and (R) is the correct explanation of (A).  

Why this answer is correct

Both (A) and (R) are true and (R) is the correct explanation of (A).  

 Key Points

  • El Nino is defined as a climate phenomenon characterized by the warming of sea surface temperatures in the central and eastern tropical Pacific Ocean.
  • This warming has significant impacts on weather patterns across the globe, including effects on marine life, especially along the Peru coast.
  • During El Nino events, the usual upwelling of cold, nutrient-rich water from the deep ocean is weakened or suppressed.
  • This upwelling is crucial for the growth of phytoplankton, which forms the base of the marine food web.
  • Without these nutrients, there is a decrease in phytoplankton productivity, which cascades through the food web, affecting fish populations and, consequently, the fishing industry and marine biodiversity along the Peru coast.

 Additional Information

  • The assertion (A) that El Nino has a strong effect on marine life along the Peru coast is true because the suppression of upwelling during El Nino leads to a decrease in the availability of nutrients, which affects the entire marine ecosystem.
  • The reason (R) provided, that during El Nino upwelling of nutrient-rich cold water is weakened, affecting phytoplankton, is also true and directly explains why El Nino has such a strong effect on marine life along the Peru coast.

Question 81

Which one of the following has maximum biomass in terrestrial ecosystem? 

  1. AOption (a)

    Tertiary consumers 

  2. BOption (b)

    Secondary consumers 

  3. COption (c)

    Primary consumers 

  4. DOption (d)

    Producers 

View answer & explanation

Correct answer

Answer: (d)D.

Producers 

Why this answer is correct

The correct answer is Producers 

Key Points

  • Producers are the organisms at the base of the food chain, like plants and algae. They convert sunlight or inorganic substances into energy-rich organic compounds through photosynthesis.
  • Secondary and Tertiary consumers are at higher levels in the food chain and obtain their energy by consuming other organisms. As energy is transferred through the food chain, some is lost as heat, resulting in a decrease in biomass at each level.
  • Primary consumers are herbivores that directly eat plants. While their biomass is higher than secondary and tertiary consumers, it is still lower than that of producers.

Therefore, producers have the maximum biomass in a terrestrial ecosystem because they capture the most initial energy and support the entire food chain. They form the foundation of the ecosystem and contribute the most to its overall biomass.

Question 82

In disaster reduction and management which one of the following is part of post-disaster stage? 

  1. AOption (a)

    Vulnerability analysis 

  2. BOption (b)

    Disaster prediction 

  3. COption (c)

    Disaster warning 

  4. DOption (d)

    Rehabilitation 

View answer & explanation

Correct answer

Answer: (d)D.

Rehabilitation 

Why this answer is correct

Rehabilitation 

Key Points Rehabilitation:

  • Rehabilitation is indeed part of the post-disaster stage.
  • This phase involves restoring communities back to normalcy after the impact of a disaster.
  • It includes rebuilding infrastructure, ensuring the return of services, and helping affected individuals and communities to recover from the disaster's effects.
<br>

Additional Information 

  • Vulnerability Analysis: This is a pre-disaster activity. It involves assessing the susceptibility of a community or area to the impact of hazards. The goal is to understand which areas, populations, or structures are most at risk and why, to inform prevention and preparedness efforts.
  • Disaster Prediction: This also falls under pre-disaster activities. Disaster prediction involves forecasting a disaster before it occurs, based on scientific data and models. This is crucial for early warning systems and for taking preemptive actions to mitigate potential damage.
  • Disaster Warning: This is an activity that spans the pre-disaster and during-disaster phases. Once a disaster is predicted or imminent, warnings are issued to inform and instruct the population on how to prepare and respond. It's about immediate short-term measures to ensure safety and minimize impact.

Question 83

Which of the following statements are not correct?

A. Stubble burning contributes to air pollution.

B. Discharge of warm water from thermal power plants into rivers does not contribute to thermal pollution.

C. Noise pollution can cause emotional or psychological effects such as irritability, anxiety and stress.

D. In mountainous areas, terrace farming is the only option to control soil erosion.

Choose the correct answer from the options given below:

  1. AOption (a)

    A and B only

  2. BOption (b)

    B and C only

  3. COption (c)

    C and D only

  4. DOption (d)

    B and D only

View answer & explanation

Correct answer

Answer: (d)D.

B and D only

Why this answer is correct

The correct answer is option 4) B and D only.

Key Points

B . The statement that "Discharge of warm water from thermal power plants into rivers does not contribute to thermal pollution" is not correct. In reality, the discharge of warm water from industrial processes, including thermal power plants, into rivers or other bodies of water does indeed contribute to thermal pollution. This increase in temperature can significantly alter the aquatic environment, affecting the oxygen levels in the water and thereby harming aquatic life and ecosystems.

D. The assertion that "In mountainous areas, terrace farming is the only option to control soil erosion" is also not correct. While terrace farming is one effective method for controlling soil erosion in mountainous areas, it is not the only option. Other methods such as afforestation (planting trees to prevent soil erosion), contour plowing (plowing along the contour lines of the land), and the use of cover crops and mulches can also help control soil erosion in these areas.

 Additional Information

A. "Stubble burning contributes to air pollution" is a correct statement. The practice of stubble burning—the burning of the straw stubble that remains after grains like paddy, wheat, etc., have been harvested—significantly contributes to air pollution by releasing large amounts of particulate matter and gases such as carbon monoxide, nitrogen oxides, and sulfur dioxide into the atmosphere.

C. "Noise pollution can cause emotional or psychological effects such as irritability, anxiety and stress" is also correct. Prolonged exposure to high levels of noise can lead to a range of health problems, including not only emotional and psychological effects but also physical health issues like hearing loss, hypertension, and heart disease.

Question 84

    C, B, D, E, A

  2. BOption (b)

    D, A, B, E, C

  3. COption (c)

    D, A, E, C, B

  4. DOption (d)

    D, E, A, C, B

View answer & explanation

Correct answer

Answer: (c)C.

D, A, E, C, B

Why this answer is correct

Correct Answer: 3) D, A, E, C, B

In a marsh community, like in many ecosystems, the food chain typically starts with plants, which are producers that convert sunlight into energy through photosynthesis. This energy is then passed through the food chain as various organisms consume each other.

Key PointsFollowing is the possible sequence of the food chain in a marsh community based on the given choices:

  • D. Green plants: They are the primary producers that provide energy for various consumers in the ecosystem.
  • A. Butterfly: Usually acts as a primary consumer that feeds on nectar from flowers and sometimes leaves of plants.
  • E. Frogs: Can act as secondary consumers by feeding on primary consumers like insects (including butterflies).
  • C. Snake: Often serves as a tertiary consumer by preying on secondary consumers such as frogs.
  • B. Hawks: Are quaternary consumers at the top of the food chain, preying on snakes among other organisms.
  • These relationships illustrate the flow of energy from producers (green plants) through various levels of consumers (from butterflies up to hawks).
  • Thus, the correct sequence of the food chain in a marsh community from the options given is:
  • D. Green plants (Primary Producers)
  • A. Butterfly (Primary Consumers)
  • E. Frogs (Secondary Consumers)
  • C. Snake (Tertiary Consumers)
  • B. Hawks (Quaternary Consumers)

    Both Statement I and Statement Il are correct. 

  2. BOption (b)

    Both Statement I and Statement Il are incorrect. 

  3. COption (c)

    Statement I is correct but Statement Il is incorrect. 

  4. DOption (d)

    Statement I is incorrect but Statement Il is correct.  

View answer & explanation

Correct answer

Answer: (c)C.

Statement I is correct but Statement Il is incorrect. 

Why this answer is correct

Option 3: Statement I is correct but Statement II is incorrect.

<br>

Key Points

 Statement I Explanation:

  • Structuralism is indeed concerned with uncovering underlying structures that determine social reality.
  • It focuses on the underlying patterns and systems that shape human behavior and social life, rather than just the surface phenomena.
  • This statement accurately reflects the goals of structuralism in sociology and anthropology, where it seeks to understand the deeper, often hidden, structures that influence social actions and relations.

Statement II Explanation:

  • This statement is incorrect in the context of structuralism. Structuralists, especially in their classic forms, tend to de-emphasize the role of individual human creativity and intentionality.
  • Instead, they focus on how individuals' thoughts and behaviors are shaped by the underlying structures of society.
  • The emphasis is more on the collective and systemic levels rather than the individual's creative capacities.
  • Therefore, saying structuralists appreciated human creativity and intentionality contradicts the core principles of structuralism.

Read the following passage and answer questions:

Risk is a product of two components: the hazard, which can be defined as the probability of occurrence of a specific event within a given time period; and the consequence, typically measured by the cost of damage or loss of life. Several environmental and human factors contribute to landslide hazard, principally by determining the susceptibility of a slope or geological system to instability. These preparatory factors include slope geometry, hydrology (surface and groundwater), soil type, underlying geology, vegetation and slope loading. Landslide triggering factors include rainfall, earthquakes, volcanic activity, changes in groundwater, erosion or undercutting and human activities (e.g. mining, construction or deforestation). Hydrological processes can exert a significant and dynamic influence on slope stability, as both a landslide preparatory factor, in terms of pore pressure and groundwater levels within the slope, and as a landslide trigger factor due to rainfall infiltration or pore pressure changes. Depending on the hydrological properties of the slope material, an increase in moisture content and pore-water pressure can reduce the mechanical strength of the slope to the point of failure. Landslide consequences depend on the type and magnitude of the landslide; the process of emplacement or runout, which determines the rate, travel distance and volume of debris (the hazard footprint); and the exposure and vulnerability of elements within the area of impact. Landslides can destroy or bury buildings, infrastructure and crops, cut off transport links, water and power supplies, and result in significant direct and indirect economic losses.

Question 87

What do you mean by hazard foot-print of landslides?  

  1. AOption (a)

    Process of emplacement. 

  2. BOption (b)

    Increase in moisture content. 

  3. COption (c)

    Travel distance and volume of debris triggered by a landslide. 

  4. DOption (d)

    Hydrological property of area.  

View answer & explanation

Correct answer

Answer: (c)C.

Travel distance and volume of debris triggered by a landslide. 

Why this answer is correct

The correct answer is Travel distance and volume of debris triggered by a landslide. 

Key Points

  • The passage defines the hazard footprint as: "the process of emplacement or runout, which determines the rate, travel distance and volume of debris."
  • This explicitly indicates that the footprint encompasses the area affected by the landslide's movement and the amount of debris deposited.
  • While other factors like process of emplacement and hydrological properties are relevant to landslides, they don't directly represent the hazard footprint as defined in the passage.

Therefore, Travel distance and volume of debris triggered by a landslide accurately captures the concept of the hazard footprint in the context of the provided information.

Question 88

The consequences of landslide mainly depend upon: 

  1. AOption (a)

    Type and mangitude of landslide. 

  2. BOption (b)

    Low intensity and low frequency of landslide. 

  3. COption (c)

    Space and time of occurence of landslide. 

  4. DOption (d)

    Instability and slope loading of the area.  

View answer & explanation

Correct answer

Answer: (a)A.

Type and mangitude of landslide. 

Why this answer is correct

Type and magnitude of landslide.

Key Points

  • The passage explicitly states that "landslide consequences depend on the type and magnitude of the landslide."
  • It further mentions that the rate, travel distance, and volume of debris (hazard footprint) determine the extent of damage.
  • Larger and faster landslides will naturally cause greater devastation compared to smaller and slower ones.

Therefore, the type and magnitude of the landslide are the primary factors influencing its consequences, making option 1) the most accurate answer.

Question 89

Which process exerts a significant and dynamic influence on slope stability? 

  1. AOption (a)

    Underlying geology. 

  2. BOption (b)

    Slope geometry. 

  3. COption (c)

    Slope loading. 

  4. DOption (d)

    Hydrological process. 

View answer & explanation

Correct answer

Answer: (d)D.

Hydrological process. 

Why this answer is correct

Hydrological process. 

Key Points

  • The passage explicitly states that hydrological processes play a significant and dynamic role in slope stability.
  • It highlights the influence of hydrology on both preparatory factors (pore pressure and groundwater levels) and triggering factors (rainfall infiltration and pore pressure changes).
  • Compared to other factors like slope geometry and underlying geology, which are relatively static, hydrological processes are constantly changing and evolving, making them a dynamic force impacting slope stability.

Therefore, Hydrological process accurately reflects the passage's description of the most influential factor on slope stability.

Question 90

Which are the triggering factors for occurence of landslides? 

  1. AOption (a)

    Slope geometry, soil type and slope loading. 

  2. BOption (b)

    Rainfall, earthquake and changes in ground water.  

  3. COption (c)

    Hydrology, underlying geology and vegetation. 

  4. DOption (d)

    Slope geometry, rainfall and soil type. 

View answer & explanation

Correct answer

Answer: (b)B.

Rainfall, earthquake and changes in ground water.  

Why this answer is correct

Rainfall, earthquake and changes in ground water.

Key Points

  • The passage explicitly states that these factors are triggers for landslides: "Landslide triggering factors include rainfall, earthquakes, volcanic activity, changes in groundwater, erosion or undercutting and human activities."
  • It distinguishes these from preparatory factors like slope geometry and soil type, which influence susceptibility to landslides, but do not directly trigger them.

Therefore, Rainfall, earthquakes, and changes in groundwater accurately represent the triggering factors for landslides as described in the passage

Question 91

Geomorphic risk is defined as: 

  1. AOption (a)

    Hazard in a given space and exposure. 

  2. BOption (b)

    Hazard in a given time and adaptation. 

  3. COption (c)

    Probability of occurence of extreme event in the given time and loss of life and property. 

  4. DOption (d)

    Vulnerability in given time and occurence of hazard.  

View answer & explanation

Correct answer

Answer: (c)C.

Probability of occurence of extreme event in the given time and loss of life and property. 

Why this answer is correct

Probability of occurence of extreme event in the given time and loss of life and property. 

Key Points

  • The passage defines risk as a product of hazard (occurrence of an event) and consequence (damage or loss).
  • It states that geomorphic risk is influenced by both preparatory factors (e.g., slope geometry, hydrology) and triggering factors (e.g., rainfall, earthquakes).
  • It emphasizes the dynamic nature of geomorphic risk, highlighting the role of time in its manifestation and potential mitigation through adaptation strategies.

Therefore, Probability of occurrence of extreme event in the given time and loss of life and property best captures the essence of geomorphic risk by considering both the temporal aspect and the possibility of adaptation to reduce its impact.

Assertion (A): Landscapes dominated by a collection of folk customs change relatively little over time, whereas modern communications facilitate frequent changes in popular customs.

Reason (R): Folk culture is more likely to vary from time to time at a given place where as popular culture is more likely to vary from place to place at a given time.

In light of the above statements, choose the most appropriate answer from the options given below:

  1. AOption (a)

    Both (A) and (R) are correct and (R) is the correct explanation of (A). 

  2. BOption (b)

    Both (A) and (R) are correct and (R) is NOT the correct explanation of (A). 

  3. COption (c)

    (A) is correct but (R) is not correct. 

  4. DOption (d)

    (A) is not correct but (R) is correct. 

View answer & explanation

Correct answer

Answer: (b)B.

Both (A) and (R) are correct and (R) is NOT the correct explanation of (A). 

Why this answer is correct

The correct option is 'Both (A) and (R) are correct and (R) is NOT the correct explanation of (A)'.

Key Points

  • Landscapes dominated by a collection of folk customs change relatively little over time, whereas modern communications facilitate frequent changes in popular customs.
  • This statement is true.
  • Folk customs are deeply embedded in local traditions and are less influenced by rapid changes in external factors, such as technology and media. Hence, these landscapes remain relatively stable over time.
  • Modern communication technologies such as the internet, social media, and global travel expose people to new ideas and trends quickly, leading to more frequent changes in popular customs.
  • Folk culture is more likely to vary from time to time at a given place whereas popular culture is more likely to vary from place to place at a given time.
  • This statement is true.
  • Folk culture changes slowly over time within the same locality, meaning variation primarily occurs over long periods.
  • Popular culture, driven by trends and mass media, can vary significantly from one place to another at the same point in time. Different regions adopt different trends influenced by their unique exposure to media and global culture.
  • While both statements (A) and (R) are true, Statement (R) is not the correct explanation of Statement (A).
  • Statement (R) discusses the spatial variance of folk and popular culture, implying that folk culture varies temporally and popular culture spatially.
  • However, Statement (A) focuses on the temporal stability of landscapes dominated by folk customs versus the rapid changes in popular customs facilitated by modern communication.
  • Thus, Statement (R) does not directly explain the cause of the temporal stability of folk customs or the rapid change in popular customs as described in Statement (A).

Additional Information

  • Folk culture includes traditional practices, music, dances, food, and clothing that are unique to a localized area and passed down through generations.
  • Popular culture means cultural patterns that are widespread and constantly changing, impacting large groups of people and often spread through mass media and modern communication technologies.
  • The dynamic between folk and popular cultures helps us understand cultural change and continuity, valuable for anthropologists and sociologists studying these patterns.

Question 96

Given below are two statements, one is labelled as Assertion (A) and the other is labelled as Reason (R).

  1. AOption (a)

    Both (A) and (R) are correct and (R) is the correct explanation of (A). 

  2. BOption (b)

    Both (A) and (R) are correct and (R) is NOT the correct explanation of (A). 

  3. COption (c)

    (A) is correct but (R) is not correct. 

  4. DOption (d)

    (A) is not correct but (R) is correct. 

View answer & explanation

Correct answer

Answer: (a)A.

Both (A) and (R) are correct and (R) is the correct explanation of (A). 

Why this answer is correct

Both (A) and (R) are correct and (R) is the correct explanation of (A).

Key Points ​

  • Assertion (A) posits that insular countries (countries comprised of islands) are geopolitically powerful states. This can be seen in examples like the United Kingdom and Japan, which have leveraged their geographical positions to become significant players on the global stage.
  • Reason (R) provides a rationale for why insular countries might be geopolitically powerful, highlighting their geographical location, advantage of navigational facilities, and access to resources. These factors can contribute to a country's ability to control trade routes, exert maritime power, and exploit exclusive economic zones (EEZs) for resources, all of which are critical elements of geopolitical power.

Additional Information 

The connection between (A) and (R) is straightforward: the unique advantages provided by their geographical settings (as described in R) are what potentially make insular countries geopolitically powerful (as asserted in A).

Question 97

From the Earth's heat budget, out of total incoming radiation, what percent is reflected back to space? 

  1. AOption (a)

    about 10 percent 

  2. BOption (b)

    about 20 percent 

  3. COption (c)

    about 30 percent 

  4. DOption (d)

    about 50 percent 

View answer & explanation

Correct answer

Answer: (c)C.

about 30 percent 

Why this answer is correct

The correct answer is about 30 percent 

Key Points

  • Earth's heat budget refers to the balance between incoming solar radiation and outgoing terrestrial radiation.
  • Of the total incoming solar radiation, approximately 30% is reflected back to space by various factors like clouds, atmospheric particles, and bright surfaces like snow and ice.
  • The remaining 70% of the incoming radiation is absorbed by the Earth's surface and atmosphere, contributing to its warming.

Additional Information

  • Option 1 (about 10 percent): This amount is significantly less than the actual reflection percentage and doesn't accurately represent the Earth's heat budget.
  • Option 2 (about 20 percent): This amount is slightly closer to the actual value but still underestimates the reflection percentage.
  • Option 4 (about 50 percent): This amount greatly overestimates the reflection percentage and is not consistent with scientific observations

Question 98

Which type of lightening has potential to cause more damage to life and property? 

  1. AOption (a)

    Inter-cloud lightning 

  2. BOption (b)

    Positive cloud-to-ground lightning 

  3. COption (c)

    Negative cloud-to-ground lightning 

  4. DOption (d)

    Intra-cloud lightning 

View answer & explanation

Correct answer

Answer: (b)B.

Positive cloud-to-ground lightning 

Why this answer is correct

The correct answer is Positive cloud-to-ground lightning 

Key Points

 

  • Positive cloud-to-ground lightning is more dangerous and has the potential to cause greater damage compared to other types of lightning because it originates from the positively charged upper regions of a thundercloud, traveling a longer distance to reach the ground.
  • Because of this long travel path, positive lightning can carry a much higher charge and can strike farther away from the storm core, often under clear skies ("bolts from the blue").
  • These lightning strikes deliver a higher amount of energy and have a longer duration than negative cloud-to-ground lightning, making them more likely to cause significant damage and fires. They are also responsible for initiating upward streamers, which can lead to powerful natural phenomena like sprites and elves above thunderstorms.

Explanation of Incorrect Options:

  • Inter-cloud lightning: This type of lightning occurs between clouds or within a single cloud, transferring charge from one part of the cloud to another. While impressive to watch, it does not directly impact the surface or ground structures and thus generally presents a lower risk to life and property.
  • Negative cloud-to-ground lightning: This is the most common type of lightning that strikes the ground, originating from the negatively charged bottom of the storm cloud. Although it accounts for the majority of lightning strikes and can certainly cause damage and injury, it typically carries a lower charge and energy compared to positive cloud-to-ground lightning, making positive strikes more destructive.
  • Intra-cloud lightning: Similar to inter-cloud lightning, intra-cloud lightning occurs within a single cloud and involves the movement of electrical charges within the cloud itself. Since it does not involve the ground, it poses less direct threat to life and property on the surface.

Additional Information 

  • Lightning, in all its forms, represents a significant weather hazard that can lead to loss of life, forest fires, and damage to structures and power systems.
  • Positive cloud-to-ground lightning, although less common than negative strikes (making up approximately 5-10% of all lightning strikes), stands out due to its higher potential for causing severe damage.
  • It's essential for safety measures and lightning protection systems to consider the impact of different types of lightning, especially in regions prone to severe thunderstorms.

Why this answer is correct

The correct answer is option 4) A, C and D only.

Key Points

  • A. Chromite deposits indeed are found in segregation masses and veins in ultra-basic rocks such as dunite, peridotite, and serpentine. Chromite, a crucial ore for chromium, is key for stainless steel and other products. India, with significant deposits in the Sukinda Valley in Odisha, among other areas, supports this mineral's extraction, aligning with the statement.
  • C . The Jamnagar oil refinery, operated by Reliance Industries, is known to have one of the largest capacities in the world and indeed uses imported crude petroleum. The refinery’s high capacity and technological capability allow it to process a wide variety of crude oils, highlighting India's capacity in handling complex refinery operations and its dependence on imported crude for meeting its energy needs.
  • D. The coastal sands of Kerala are rich in heavy minerals like ilmenite, rutile, zircon, and monazite. Among these, monazite is significant because it contains thorium, which is pivotal for India's future nuclear energy plans. Kerala, along with other parts of the Indian coastline like Tamil Nadu and Odisha, has substantial reserves of these minerals, making India one of the leading producers of such heavy minerals.

Additional Information

  • Natural resources and infrastructure, such as those mentioned in statements A, C, and D, are crucial for India's economic development.
  • Chromite mining, oil refinery operations, and heavy mineral sands exploitation contribute significantly to India's industrial capacities and strategic reserves.
  • Biosphere Reserves, through their zonation strategy (core, buffer, and transition zones), provide an excellent example of how conservation and sustainable use of resources can coexist, pivoting more towards ecological balance rather than industrial growth.
  • Understanding and managing these resources and developments thoughtfully is key to achieving sustainable development objectives and ensuring environmental conservation alongside economic progress.

Answer: (c)C.

A, D, C, B

Why this answer is correct

A, D, C, B

Geomorphology, the scientific study of the origin and evolution of the Earth's landforms, relies on various principles and theories to understand the complex processes shaping the planetary surface. 

Key PointsHere's a look at the concepts listed in your question, arranged chronologically:

  • Principle of Uniformitarianism (A): Formulated by James Hutton in the late 18th century and later popularized by Charles Lyell in the 1830s, this principle asserts that the same natural laws and processes that operate in the universe now have always operated in the universe in the past and apply everywhere. It is often summarized by the phrase "the present is the key to the past." It laid the foundation for much of the modern understanding of Earth processes.
  • Geographical cycle of erosion (D): Proposed by William Morris Davis in the 1890s, this theory describes a cycle of erosion that landscapes go through, starting with uplift and followed by a long period of decline in relief through "youth," "maturity," and "old age." His model was among the first to detail a comprehensive theory of landscape evolution.
  • Die Morphologische Analyse (C): This concept, which translates to "The Morphological Analysis of Landforms," was introduced by Walther Penck in 1924. Penck's work focused on a theoretical framework that opposed some aspects of Davis's cycle of erosion, offering alternative views on how landscapes evolve over time, particularly emphasizing uplift and the role of processes over different scales.
  • Dynamic Equilibrium Theory (B): Developed in the second half of the 20th century, this theory suggests that landscapes develop in such a way that they maintain a state of balance or equilibrium between the forces that uplift the earth's surface and the processes that wear it down. Most notably associated with geomorphologists like Luna Leopold and M. Gordon Wolman in the 1960s, it integrates ideas from hydrology and sediment transport, proposing that systems adjust to maintain this balance.

 

Thus, the chronological order (old to recent) in terms of inception is: Option 3) A, D, C, B

 

Additional Information 

  • Principle of Uniformitarianism underpins much of geology and geomorphology by suggesting that understanding contemporary processes allows scientists to interpret past landscapes.
  • Geographical cycle of erosion provided a model for how landscapes evolve from birth to death, a concept that has been refined but remains foundational.
  • Dynamic Equilibrium Theory reflects the complexity and self-regulating aspects of geomorphic systems, highlighting the interactions between different processes at play.
  • Die Morphologische Analyse introduced critical challenges to existing theories, promoting a more dynamic and integrated understanding of landscape evolution.
