Drumlins are long, tear-shaped hills formed by glacial action during the last Ice Age. They are typically found in areas that were covered by glaciers, such as parts of North America, Europe, and Asia. Drumlins are made of compacted glacial till, a mixture of clay, sand, gravel, and boulders that were deposited by the moving glacier.
Drumlins are usually oriented in the direction of the glacier's movement, with their pointed ends pointing in the direction of ice flow. They can vary in size, but typically range from tens to hundreds of meters in length and tens of meters in height.
These landforms are important because they provide clues about the direction and flow of ancient glaciers. They also have a significant impact on the landscape and can affect things like drainage patterns and the behavior of rivers and streams.
