Important erosional feature formed by the glacier are (a) cirque (b) U-shaped valleys and depositional feature is moraines.
Cirque The glacier scoops or plucks the rocks while moving down the slope from its snow covered valley head forming a depression known as a cirque or corrie. It is a horse-shoe shaped basin or an arm chair shaped basin. Snow accumulates in the depression which has a flat floor and steep slopes. U-shaped valley Glacier is a thick mass of ice unlike a river. While moving down it plucks, scoops, and erodes its bed and sides. It forms a deep, broad, steep valley resembling a ‘U’. It has a wide flat floor.
Moraines the eroded rock fragments of varying sizes which the glacier deposits when it melts is known as the moraines. There are lateral moraines, ground moraines, medial moraines and terminal moraines.
