Answer: (d)D.

1 and 3

Why this answer is correct

The correct answer is 1 and 3.

Key Points

Lake Victoria

  • Lake Victoria is actually the second-largest freshwater lake in the world by surface area. Hence statement 1 is incorrect.
  • It is located in East Africa and is part of the African Great Lakes system. Hence statement 2 is correct.
  • Lake Superior, one of the Great Lakes of North America, is the largest freshwater lake by surface area, while Lake Victoria comes second in that regard.
  • It is bordered by Tanzania, Uganda, and Kenya, but not Rwanda. Hence statement 3 is  incorrect.
  • Lake Victoria is drained solely by the Nile River near Jinja, Uganda, on the lake's northern shore.
  • Only outflow from Lake Victoria is the Nile River, which exits the lake near Jinja, Uganda. Hence statement 4 is correct.

Additional Information

  • Lake Victoria is considered a shallow lake considering its large geographic area with a maximum depth of approximately 80 metres and an average depth of 40 metres.
  • Lake Victoria formerly was very rich in fish, including many endemics, but a high percentage of these became extinct during the last 50 years.
  • The main group in Lake Victoria is the haplochromine cichlids with more than 500 species, almost all endemic, and including an estimated 300 that still are undescribed.
  • The Victoria haplochromines are part of an older group of more than 700 closely related species, including those of several smaller lakes in the region, notably Kyoga, Edward–George, Albert, and Kivu.
  • In recent history only Lake Kyoga was easily accessible to Victoria cichlids, as further downstream movement by the Victoria Nile is prevented by a series of waterfalls, notably Murchison.

  4. DOption (d)

    Neither 1 nor 2

View answer & explanation

Correct answer

Answer: (d)D.

Neither 1 nor 2

Why this answer is correct

The correct answer is Neither 1 nor 2.

Key Points

  • Heat Wave need not be considered till maximum temperature of a station reaches at least 40°C for Plains and at-least 30°C for Hilly regions. Hence both the statement is incorrect.
  • If the normal maximum temperature of a station is less than or equal to 40°C, then an increase of 5°C to 6°C from the normal temperature is considered to be heat wave condition.
  • Further, an increase of 7°C or more from the normal temperature is considered a severe heat wave condition.

Additional Information Heat Wave:

  • Heat wave as a hazard causing disaster scenario, is little more than the physical phenomenon of high heat conditions and is characterized as a complex of hydro-climatic risks coupled with social, occupational and public health risks.
  • If the normal maximum temperature of a station is more than 40°C, then an increase of 4°C to 5°C from the normal temperature is considered to be heat wave condition. Further, an increase of 6°C or more is considered a severe heat wave condition.
  • El Nino often increases temperatures in Asia, combined with the weather pattern to create record high temperatures.
  • Trade winds coming from South America normally blow westward towards Asia during Southwest Monsoon and warming of the Pacific Ocean results in weakening of these winds.

Impacts of Heat wave:

  • sunburn phenomenon with pinkish skin resulting in burning of skin and pain sensation.
  • Giddiness, vertigo headache and sudden onset drowsiness/unconsciousness.
  • Edema (swelling) and Syncope (Fainting) are generally accompanied by fevers below 39°C i.e.,102°F.
  • Body temperatures of 40C i.e., 104F or more along with delirium, seizures or coma. This is a potentially fatal condition.
