Drumlins

Drumlins are elongated, tear-shaped landforms that are commonly found in areas that have been covered by glaciers. They are formed by the movement of glacial ice and the deposition of glacial sediments.

Formation of Drumlins

Drumlins are formed beneath a glacier as it moves over the landscape. As the glacier advances, it picks up and carries a mixture of sediments such as sand, gravel, and boulders. These sediments are then deposited in the shape of a drumlin as the glacier retreats. The direction of the drumlins indicates the direction of the glacier's movement.

Characteristics of Drumlins

Drumlins are characterized by their elongated shape, with a steep slope on the stoss (upstream) side and a gentle slope on the lee (downstream) side. They are typically composed of till, a mixture of clay, sand, and gravel that has been deposited by the glacier.
