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.
What else can I help you with?
Which glacial landforms require more than one glacier to form?
aretes,hanging valleys,horns,and drumlins
How are erratics and drumlins alike?
Erratics and drumlins are both types of geological formations associated with glacial activity. Erratics are large boulders transported and deposited by glaciers, often found in areas where the surrounding rock is different from the rock type of the erratic. Drumlins, on the other hand, are elongated hills formed from glacial till that has been shaped by the movement of ice. Both features provide evidence of past glacial movements and help in understanding the dynamics of glacial landscapes.
What is 08 on fraction form?

What is the full form form of child?
Child is the full form of child.
Where are drumlins and eskers usually found?
Drumlins are usually found in regions that were covered by glaciers during the last Ice Age, such as parts of North America and Europe. Eskers are commonly found in areas that were once covered by glaciers, including parts of Scandinavia, North America, and Siberia.
What landforms would be created by outwash A moraines B eskers C drumlins D erratics?

What form by glacial erosion?
Eskers
What glacial features results from deposition?
Moraines, drumlins, eskers, and outwash plains are glacial features that result from deposition. Moraines are ridges of till deposited along the edges of a glacier, drumlins are elongated hills of glacial till, eskers are long, winding ridges of sand and gravel, and outwash plains are flat areas of sand and gravel deposited by meltwater streams flowing away from the glacier.
What is the difference between a drumlin and an esker?
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.
What are the different types of glacial deposition?
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.
What are 4 glacial deposition features?
Some glacial deposition features include moraines, drumlins, eskers, and outwash plains. These features are a result of the deposition of sediment and rocks carried by glaciers as they move and melt.
Where would you find glacial till?
Glacial till can be found in areas where glaciers have deposited material as they advance and retreat, such as moraines, drumlins, and eskers. It is commonly found in regions that have experienced glaciation, such as parts of North America, Europe, and Antarctica.
When deposits of till build up What is left behind?
When deposits of till build up, they can leave behind various landforms such as moraines, drumlins, eskers, and outwash plains. These features are created by the movement of glaciers and the deposition of sediments as the glacier retreats.
What are glaciers forming long smooth hills?
They are called drumlins.
How Eskers are glacial features formed when .?
Eskers are formed when a subglacial stream of meltwater flows within, on, or beneath glaciers. As the glacier melts and retreats, sediment and gravel carried by the stream are deposited in long winding ridges. These deposits form the characteristic winding shape of eskers.
What are some features formed by glacial deposition?
Some features formed by glacial deposition include moraines (ridges of till), drumlins (elongated hills), eskers (sinuous ridges of sand and gravel), and kettles (depressions formed by melting ice blocks).
