Question
Name two important land forms of river erosion.
✓
Answer
The two landforms resulting from erosion in the upper course of a river are the following :
V-shaped Valleys: It is formed from a stream eroding downward, through a process, called down cutting. These valleys are formed in the initial stages of rivers and have steep slopes.
I-shaped Valley: In regions of hard rocks it develops almost vertically in an I-shape. River valleys are normally formed in areas of sufficient rainfall and where rocks are not very hard or resistant.
