Kame is a hill or mound of sand and gravel formed by glacial meltwater, whereas an esker is a long winding ridge of material deposited by a stream flowing beneath a glacier. Essentially, the key difference lies in their shape and formation process within a glacial environment.

How is an esker made?

An esker is formed by the deposition of sand and gravel carried by meltwater streams flowing within or on top of glaciers. As the glacier melts, the sediment is deposited in ridges or sinuous mounds along the path of the flowing water, creating a long, narrow ridge known as an esker.


Which formation is a long winding ridge made from deposits of sand and gravel?

A long winding ridge made from deposits of sand and gravel is called an esker. Eskers are formed by the melting of glaciers and the deposition of sediment as the flowing water carries and deposits material in a sinuous ridge-like form.


What are some examples of Eskers?

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. see : http://en.wikipedia.org/wiki/Esker


How can an esker be quickly differentiated from a moraine by its sediment?

Since the esker was deposited in a flowing water regime, I would not expect to find many fine clays there. And I would not expect to find any large boulders, >1m in an esker. The moraine on the other hand will have parts that have been formed by rocks grinding each other in a comparatively waterless regime. So it will have lots of fine clays. Boulders >>1m could even be a feature of a moraine.
