Glacial Processes and Landforms

A glacier is a moving river of ice on land. In this video Geography teacher Darron Gedge discusses how glaciers are formed and how the processes of glacial erosion, transportation and deposition create various types of land forms. The main glacial erosion processes are plucking, abrasion, and freeze-thaw. Landforms made by glaciers include moraines, drumlins, pyramid peaks, cirques, ribbon lakes, tarns, hanging valleys, aretes, fiords and U shaped valleys. This video was manly filmed in the South Island of New Zealand. Satellite images in the video are provided by Google and its map data providers.
