As glaciers move, they erode the land in two ways: plucking and abrasion.
Different types of glaciers erode the landscape in very different ways:
The following slides outline features resulting from glacial erosion, and explains how they are formed.
Alluvial fana triangle shaped deposit of gravel, sand and smaller pieces of sediment such as silt. Created by flowing water. Associated with alpine glacier
A plain formed of glacier sediments deposited by meltwater at the terminus of the glacier. Associated with continental glacier.
A stream in a valley which is larger than would be predicted based on the stream’s erosive power
Ribbon lakea long narrow lake found in a glacial trough. On area of alternating bands of hard and soft bedrock.
Loose debris or talus accumulated at the foot of a cliff comprised of angular stones and boulders
