Question
How do glaciers accomplish the work of reducing high mountains into low hills and plains?
Solution
Erosion by glaciers is tremendous because of friction caused by sheer weight of the ice. The material plucked from the land by glacier get dragged along the floors or sides of the valleys and cause great damage through abrasion and plucking. Glaciers can cause significant damage to even un-weathered rocks and can reduce high mountains into low hills and plains.As glaciers continue to move, debris gets removed, divides get lowered and eventually the slope is reduced to such an extent that glaciers will stop moving leaving only a mass of low hills and vast outwash plains along with other depositional features.
