Suppose that you are on an expedition to study mountains in a polar climate. On one of the slopes, you find a large deposit of sediment. How was the sediment likely produced?

As explained below.

Explanation:

The glacier's weight that is combined with the gradual movement, can alter and reforms the landscape over hundreds the thousands of the years. The ice then erodes the land surface and this can break the rocks and the soil debris far from their original places, resulting in various glacial landforms. The Glaciers retreat also leads to the rise of the large sets of the sediments that are being deposited when the terminal extends as far down valley as it previously did. The Glaciers retreat as the ice melts more quickly than snowfall can accumulate and thus form the new glacial ice.
