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.
Following this video lesson, you will be able to: 1  Define glacier and generally describe how glacial erosion occurs. 2  Describe the two main processes of glacial erosion: plucking and abrasion. 3  Identify the landforms and features that result from glacial erosion.
