Drumlins
A moraine drumlins
Moraines are formations made of till (rock, sand, and clay) deposited by glaciers, while drumlins are elongated hills made of glacial deposits shaped by the moving ice. Moraines are typically ridges or mounds, while drumlins have a streamlined shape with a gentle slope facing the direction the glacier advanced.
These are called drumlins. Drumlins are smooth, elongated hills composed of till that have been shaped by the movement of an overriding glacier or continental ice sheet. They are typically oriented in the direction of ice flow and are common features in areas that were once covered by ice sheets during the last glacial period.
They are called drumlins.

These long smooth hills are known as drumlins, which are created by the movement of glaciers during the process of glaciation. As a glacier advances, it reshapes the landscape by depositing and sculpting materials, forming these distinctive elongated landforms. Drumlins are typically found in regions that were once covered by ice sheets during the last Ice Age.

Drumlins are elongated, streamlined hills formed by the movement of glacial ice. They are created as glaciers advance, shaping subglacial sediment and debris into a teardrop or boat-like shape. The orientation and form of drumlins are influenced by the direction of glacier flow, and they often consist of till—a mix of clay, silt, sand, and boulders. Their formation typically occurs beneath the ice, as the glacier reshapes the underlying landscape.
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.
A drumlin is a smooth, elongated mound of glacial till formed by a moving glacier, while an esker is a long, winding ridge of sand and gravel deposited by a meltwater stream flowing in tunnels within or beneath a glacier. Drumlins are typically shaped like hills while eskers are long, narrow ridges.
Moraines are formations made of till (rock, sand, and clay) deposited by glaciers, while drumlins are elongated hills made of glacial deposits shaped by the moving ice. Moraines are typically ridges or mounds, while drumlins have a streamlined shape with a gentle slope facing the direction the glacier advanced.
A glacier formed long smooth hills are called drumlins. They are created when a glacier slides over the ground and reshapes the underlying material, depositing sediments and creating elongated, tear-shaped landforms. Drumlins are typically found in areas that were once covered by glaciers.
A glacier builds up a moraine in front of it as it pushes dirt and rock ahead of it.
The main types of glacial deposition are till, moraines, drumlins, eskers, and outwash plains. Till is unsorted sediment deposited directly by the glacier, while moraines are ridges of till deposited at the glacier's margin. Drumlins are smooth, elongated hills formed under glacial ice, eskers are winding ridges of sand and gravel deposited by meltwater streams, and outwash plains are flat areas of sorted sediment deposited beyond the glacier by meltwater.
These are called drumlins. Drumlins are smooth, elongated hills composed of till that have been shaped by the movement of an overriding glacier or continental ice sheet. They are typically oriented in the direction of ice flow and are common features in areas that were once covered by ice sheets during the last glacial period.
