Quizplus · Accepted Answer

Eskers are long, narrow ridges of stratified sand and gravel that were deposited by streams flowing on or within glaciers. They form in tunnels or channels within the ice and are left behind as the ice melts. Eskers are commonly found in till plains and are one of the most distinctive glacial landforms. Drumlins are oval-shaped hills that are typically composed of glacial till and are also found in till plains. Kames are small, cone-shaped hills that form when sediment is deposited by meltwater streams flowing over the surface of the glacier. Kettles are depressions or holes that form when blocks of ice left behind by a retreating glacier melt and fill with water.
