Question

Explain the erosional work of glaciers.

Accepted Answer

When the glacier starts melting, its capacity to carry load is reduced. Thus, rocks are deposited on the sides and floor of the valley. These deposits form glacial moraines.

The glacier carves out deep hollows along the slope of a mountain. It develops an armchair-like depression, called cirque. When glacial ice melts, the depression is filled up with water and forms a lake. This lake is called tarn.

When the glacier passes through a valley, rock fragments fall into moving ice from the mountain slopes. It also picks up rock pieces from the valley floor. These rocks act as tools of erosion. These rocks rub against the sides and the valley floor. This creates a U-shaped valley with a flat bottom and almost vertical sides.
