Answer 1

Explain three erosional landforms

Solution:

• Gorges and Canyons: When the river flows through a mountainous region made up of hard rocks, it forms a valley with almost vertical sides called gorge. A deep gorge with steep sides that runs for hundreds of kilometers is referred to like a canyon.
• Waterfall: When a river flows in a region where hard rocks lie over soft rocks horizontally, the soft rocks get eroded quickly and the hard rocks project outwards. Thus, the river falls vertically from a steep slope to form a Waterfall.
• V-shaped valley: A ‘V’- shaped valley is formed by the vertical erosion of the river where the valley is deepened and widened.
