As nouns the difference between drumlin and esker is that drumlin is (geography) an elongated hill or ridge of glacial drift while esker is a long, narrow, sinuous ridge created by deposits from a stream running beneath a glacier. A drumlin is an elongated hill or mound that has been shaped by a glacier or ice sheet moving over it. An esker is a ridge of sediment and ditritus that is deposited at the base along the length of the glacier by the outwash from the meltwater pro So eskers and kames have som relationship in the origin of the sediment that make them up. Drumlins are of completely different processes. Much more could be said and all details are not completely understood when it comes to many glacial landforms and their formation. Drumlins are formed by glacial movement; eskers from streams under the glacier.

The difference between moraines, drumlins, and eskers is old moraines form the material into elongated landforms. Drumlins steeper slope faces the direction from where the glacier came. Eskers … 2018-10-14 Drumlins are hills created by moving glaciers and their meltwaters. They are composed of similar sediment to those of eskers and other glacial hills, however they are formed by the glacial push, unlike eskers. Drumlins occur when sediment is pushed up onto existing sediment on a slope.

Not all drumlins taper like this, though. Because they have been streamlined by flowing ice, scientists often use them to understand past glacier flow directions. They are longest in the direction of flow. Eskers are the structures formed when the glacial meltwater carried the sediments and deposit it in subglacial tunnels, therefore they can provide vital information about the dynamics and shapes of ice sheets and glaciers whereas, Drumlis are formed when the ice sheets move in streamline over the rock debris. What are Eskers, Drumlins, and Moulins?

The degree to which the surface in the area of these land-forms has been eroded seems to increase from spindle drumlins (spindle-shaped landforms can be ridges or drumlin definition: 1. a small hill formed by a glacier (= mass of moving ice), usually with a stretched, oval shape….

My impression is that an esker is longer than a drumlin, which is longer than a kame. What other differences distinguish between the three? The steep sections along with the peaks of drumlins are up-ice end. They are caused by glacier flow and the tapered end of the drumlins point in the direction of glacier flow. Esker drumlins can also form when the glacier flows over a deeper patch of sediment; the weight of the glacier moulds it into a drumlin shape through pressure. after drumlins have been formed, further glacial action can alter their shapes.

Eskers may range from 16 to 160 feet (5 to 50 m) in height, from 160 to 1,600 feet (500 m) in width, and a few hundred feet to tens of miles in length. Some glacial landforms, such as drumlins and eskers, clearly indicate a landscape produced by subglacial processes. Other landforms, such as large channels known as tunnel channels or tunnel valleys, were produced subglacially by pressurized water flows directed toward the margin of the ice sheet.
