The difference between moraines, drumlins, and eskers is old moraines form the material into elongated landforms. Drumlins can vary widely in size, with lengths from 1 to 2 km (0.6 to 1.2 miles), heights from 15 to 30 m (50 to 100 feet), and widths from 400 to 600 m. Most drumlins are composed of … Drumlins are elongated hills of glacial deposits. Drumlins and eskers are found in glacial areas. 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 produced by the pressure from the weight of the ice. They are longest in the direction of flow. 4. Exposed bedrock reveals widespread scalloping … Drumlins are hills made of glacial sediment and till, while eskers are long ridges of glacial drift. Drumlin, smooth, half egg-shaped or ellipsoidal hill which formed beneath Quaternary GLACIERS. 2. Kames may be cone […] If you've made changes, tell the reviewer what changes you made. 3. They lie parallel to the direction of ice movement, the blunt (stoss) end facing up-glacier, the lee sloping down-glacier.
