Glacial Erosion and Transportation Processes
This video is part two of a four part series on glaciers. As glaciers move, glacial erosion processes take place causing the glacier to transport large quantities of material with them. The erosion processes of glaciers include plucking, abrasion and freeze-thaw. Abrasion can leave behind smooth polished surfaces. Sometimes these surfaces have scratches in them called striations that have been carved out by debris embedded in the base of the glacier. At the end of glaciers there is often a glacial lake where ice bergs can be seen breaking away from the glacier in a process known as calving.
This video was filmed in the South Island of New Zealand.
