Answer:
Plucking
ExplantionPlucking is the method through which erosion happens during glaciations. The movement of ice and glaciers scrapes along the rock that surrounds it while pulling ways the pieces of the foundation that results in corrosion.
Glacier causes erosion in two ways it can be either by plucking or abrasion, plucking occurs when the sediments pick up the glacier. They then freeze below the glacier thus being always carried by ice when it is flowing. Abrasion happens when the glaciers scrapes towards the earth’s service.
