Erosion by Glaciers. Like flowing water, flowing ice erodes the land and deposits the material elsewhere. Glaciers cause erosion in two main ways: plucking and abrasion. Plucking is the process by which rocks and other sediments are picked up by a glacier. They freeze to the bottom of the glacier and are carried away by the flowing ice.
Glaciers can be characterized in two ways based on their formation: alpine and continental. There are two types of glacial movement: sliders and creepers. Sliders travel along a thin film of water located on the bottom of the glacier.
