Answer:
This is the process by which a glacier steepns the back wall in the mountains.
Answer:
Glacial are masses of flowing ice that have accumulated on land in areas where the annual input of frozen precipitation, especially snowfall, has exceeded its yearly loss by melting and other processes. A glacier, in general, is a mass of ice that moves very slowly downhill. It normally assumes a tongue-shape, broadest at the source but becoming narrower downhill. Iceberg refers to individual block of ice shelves after they break up.

By plucking the glacier freezes the joints and beds of the underlying rocks, tears out individual blocks and drags them away. By abrasion, the glacier scratches, scrap, polishes and scours the valley floor with the debris frozen in to it.
