An esker is a type of hill made up of glacial debris (sort of a moraine). They are generally found in areas that have had continental glaciation (past ice ages) and differ from the moraines seen at the edges of glacier ice sheet in that they are elongated in the direction of ice sheet flow. Esker is from old Irish meaning "ridge". A esker is commonly long and sinuous.

What else can I help you with?
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.
How are eskers formed and what geological processes contribute to their unique formation?
Eskers are formed by meltwater streams flowing within or beneath glaciers during the last Ice Age. As the glaciers melted, the sediment and rocks carried by the streams were deposited in long, winding ridges. The unique formation of eskers is primarily due to the deposition of sediment by these meltwater streams, as well as the reshaping of the landscape by the movement of the glaciers.
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.
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).
Is esker cause by glacial erosion?
No, eskers are not caused by glacial erosion. Eskers are long, winding ridges of sand and gravel that are formed by meltwater streams flowing in tunnels within or under glaciers. Glacial erosion refers to the process by which glaciers carve and shape the land through the movement of ice and debris.

What is a long hill formed by material carried by glaciers?
Eskers
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.
Eskers and Kettle lakes are the result of?
Eskers are winding ridges of sediment deposited by meltwater streams flowing under glaciers. Kettle lakes are formed when a block of ice from a retreating glacier gets buried in sediment and then melts. Both eskers and kettle lakes are common features of glacial landscapes.
Features that are thought to be deposited in tunnels that run beneath the ice are?
eskers.
What is an area at the leading edge of glacier where meltwater deposits outwash?
eskers
