Why are drumlins this shape?

Drumlins are elongated, hill-like landforms that typically have a streamlined shape, formed by the movement of glacial ice. As glaciers advance, they erode and reshape the underlying landscape, depositing sediment in a manner that creates the characteristic teardrop or oval shape of drumlins. The tapering end points in the direction of glacier movement, while the broader end faces the opposing side. This formation process results in their distinctive profile, reflecting the dynamics of glacial flow and the deposition of materials.
