Glacial erosion involves the removal and transport of bedrock or sediment by three main processes: quarrying (also known as plucking), abrasion, and melt water

Glaciers are Sculptors! Glaciers sculpt and carve away the land, transport material, and create glacial landforms. A landscape can be dramatically re-shaped from a glacier’s passing. When glaciers carve and sculpt they are eroding the landscape. Eroding means to move dirt, rock, or other material from the ground.

Land reclamation, the process of improving lands to make them suitable for a more intensive use. Till or glacial till is unsorted glacial sediment..

When the ice moves downhill, rock is plucked from the back wall.

There are three main types of glacial erosion - plucking, abrasion and freeze thaw. Plucking is when melt water from a 9 Feb 2018 Glacial Erosion. Schematic showing plucking and abrasion of bedrock beneath a glacier This diagram shows how glaciers can erode bedrock.

Definitions of some key words used can be found below. This video exp Abrasion is the process in which a glacier scrapes underlying rock. Depending on the type of force, erosion can happen quickly or take thousands of years. Glacial Erosion - Glaciers erode in several ways. When the glacier moves again the rock is pulled away or ‘plucked’ from the base of the valley.
