Drumlin - GCSE Geography Definition

A drumlin is a smooth, elongated hill formed by glacial action. They are usually composed of mixed sediment known as till. These landforms are often found in clusters, creating a "basket of eggs" topography, and are aligned in the direction of ice movement, with the tapered end pointing down-ice. Drumlins are significant for GCSE Geography students as they provide evidence of the past presence and movement of glaciers, helping to illustrate processes of glacial erosion and deposition in landscapes shaped during the last Ice Age. Understanding drumlins aids in recognising the impact of glacial processes on the physical landscape.
