The correct answer is Hard rocks.

Key Points

• Gorges are deep valleys with steep, almost vertical walls, commonly formed by the erosive action of rivers over geological time.
• They are most commonly developed in hard rock formations because these rocks resist erosion better than softer materials, allowing the river to cut deep, narrow valleys rather than wide ones.
• Examples of hard rocks where gorges are formed include granite, basalt, and other igneous or metamorphic rocks.
• Famous gorges like the Grand Canyon in the USA and Kali Gandaki Gorge in Nepal were carved through hard rock formations by persistent river erosion.
• The steep walls of gorges are created as the hard rock resists weathering and collapsing, maintaining the narrow and deep profile of the valley.

Additional Information

• Soft sediment:
• Soft sediment consists of loose, unconsolidated materials such as sand, silt, and clay, which are easily eroded by water and wind.
• In areas dominated by soft sediment, rivers typically form wide valleys or floodplains rather than narrow gorges.
• These areas are more prone to erosion and deposition processes, leading to the formation of features like meanders and oxbow lakes.
• Glacial till:
• Glacial till is an unsorted mixture of sediments deposited directly by glacier ice.
• It does not form gorges, as it lacks the structural integrity required to create steep walls.
• Instead, glacial till can form moraines, drumlins, and other glacial landforms.
• Volcanic ash:
• Volcanic ash consists of fine particles of volcanic glass and minerals ejected during volcanic eruptions.
• It is highly susceptible to erosion and compaction, making it unsuitable for gorge formation.
• However, volcanic activity can create other landforms, such as calderas, lava plateaus, and volcanic cones.
• Gorge Formation:
• Gorges are typically formed by the long-term erosive action of rivers cutting through resistant rock layers over millions of years.
• Other factors, such as tectonic uplift and changes in sea level, can enhance the formation of gorges by increasing river gradient and erosive power.
• Gorges can also be formed by glacial activity, where a glacier carves out a U-shaped valley that later becomes a gorge after glacial retreat.
