The sediment deposited by glaciers is called . When a chunk of ice left behind by a receding glacier melts, the water stays in the kettle, forming a .

Answer 1

Answer 2

Answer: 1. Plucking

2.Moraine

3. Kettle lake

Plucking is a process of erosion in glacier in which rocks and sediments are displaced by the glacier to other locations. These rocks and sediments gets freeze at the bottom of the glacier.

A moraine is a sediment deposited by a glacier. This may be in a form of thick layer of sediment called as ground moraine or a small ridge of deposits called as end moraine.

A kettle lake is formed when ice in large extent gets melted and this results in formation of depression which is called as kettle. The kettle is filled by melted water forming a lake or kettle lake.
