Question

Quizplus · Accepted Answer

Drumlins are elongated hills made of till, which is a mixture of unsorted glacial sediments such as sand, clay, and gravel. This material is deposited by glaciers as they advance and retreat, eventually forming the streamlined shape of a drumlin. While drumlins may contain fragments of bedrock and striations (grooves made by glacial abrasion), the main component is drift. Ice itself does not form drumlins, though it plays a crucial role in their formation by eroding and transporting the sediments that eventually become drumlins.
