Which term describes a gentle, dome-shaped hill composed of glacial till left behind underneath a retreating or advancing ice sheet, oriented parallel to the direction of ice flow?

A. Kame
B. Drumlin✓ Correct Answer
C. Esker
D. Moraine

💡 Solution & Explanation

A drumlin is a streamlined, elongated, dome-shaped hill formed by glacial action consisting of till, aligned parallel to the direction of ice movement. In contrast, kames are irregular mounds of stratified drift, eskers are winding ridges of sand and gravel deposited by meltwater streams, and moraines are ridges of unsorted debris dropped directly by melting glaciers. Glacial depositional landforms serve as key indicators of past ice sheet extents during the Pleistocene epoch.
