Drumlins are oval-shaped hills, largely composed of glacial drift, formed beneath a glacier or ice sheet and aligned in the direction of ice flow.
Q. Why are drumlins called basket of eggs?
Drumlins. Drumlins are low hills that were formed and shaped by the flow of ice during the last Ice Age. The end facing the ice is blunter. Drumlins may occur in great swarms thereby creating what is sometimes described as ‘basket of eggs’ topography.

Q. Why are drumlins smooth shape?
Drumlins – these are mounds of glacial material, deposited by the glacier. The exact process of formation is not known. They lie parallel to the direction of the ice movement. They have a smooth elongated shape because of later ice movement over them.
Q. Where are drumlins generally found?
Drumlins are commonly found in clusters numbering in the thousands. Often arranged in belts, they disrupt drainage so that small lakes and swamps may form between them. Large drumlin fields are located in central Wisconsin and in central New York; in northwestern Canada; in southwestern Nova Scotia; and in Ireland.
Q. Where are eskers found?
Notable areas of eskers are found in Maine, U.S.; Canada; Ireland; and Sweden. Because of ease of access, esker deposits often are quarried for their sand and gravel for construction purposes.
Q. What are drumlins and eskers formed by?
Eskers and Drumlins are features formed by glacial action. stream, carved into a base of glacial ice. they go over deposited moraines, they form new ones, and can reshape them into drumlins. Drumlins are steep going up the glacier, and gentle going down.
Q. What are drumlins made of?
Drumlins are elongated, teardrop-shaped hills of rock, sand, and gravel that formed under moving glacier ice.
Q. How are crag and tails formed?
A Crag and Tail consists of a large mass of resistant rock on the STOSS (upslope side) and a gently sloping tail (on the LEE side) of less resistant rock. This is a geological formation caused by the passage of a glacier over an area of hard rock and softer rock.
Q. Are drumlins sorted or unsorted?
Drumlins are formed in groups underneath the ice. Outwash deposits are made by the meltwater flowing away from the ice. A broad, stratified (layered or sorted), gently sloping surface is an OUTWASH PLAIN. The wind can pick up and blow the ground up rock flour, distributing it over wide areas.
