A Corrie lake is formed as follows :

How Is a Corrie Formed?

Answer

A corrie is formed in different steps. First, the snow accumulates in a hillside hollow and turns to ice. Then, the hollow is deepened by abrasion and plucking and the ice in the corrie moves under the influence of gravity, deepening the hollow still further. Since the ice is at the foot of the hollow and moves more slowly, a rock lip forms. When the ice melts, a lake or tarn may be formed in the corrie. The steep back wall may be severely weathered by freeze€“thaw weathering, providing material for further abrasion.
