How can glaciers cause deposition?

(1) Answers

Glaciers deposit their sediment when they melt. They drop and leave behind whatever was once frozen in their ice. It’s usually a mixture of particles and rocks of all sizes, called glacial till. Water from the melting ice may form lakes or other water features. Moraine is sediment deposited by a glacier. A ground moraine is a thick layer of sediments left behind by a retreating glacier. An end moraine is a low ridge of sediments deposited at the end of the glacier. It marks the greatest distance the glacier advanced. A drumlin is a long, low hill of sediments deposited by a glacier. Drumlins often occur in groups called drumlin fields. The narrow end of each drumlin points in the direction the glacier was moving when it dropped the sediments. An esker is a winding ridge of sand deposited by a stream of meltwater. Such streams flow underneath a retreating glacier. A kettle lake occurs where a chunk of ice was left behind in the sediments of a retreating glacier. When the ice melted, it leaves a depression. Hope this helps ;)
