How do drumlins and eskers form? - Answers

Drumlins and eskers are landforms created by glacial activity. Drumlins are elongated hills formed by the movement of glacial ice, which shapes the underlying sediment into a streamlined form as the glacier advances and retreats. In contrast, eskers are long, winding ridges of sediment deposited by meltwater streams that flow beneath or within a glacier, leaving behind layers of sand and gravel as the glacier retreats. Both features are indicators of past glacial processes and provide insights into the dynamics of ice movement.
