A branch of geomorphology concerned with landscapes occupied by glaciers, and with landscapes which have been glaciated when they were covered by glaciers in the past. The purpose of glacial geomorphology is to provide physically based explanations of the past, present and future impacts of glaciers and ice sheets on landform and landscape development. Although knowledge of glacier accumulation, the physics of flow and the mass balance is necessary glaciological background, glacial geomorphology is concerned with the results of present glacier dynamics and with the way in which glaciers produce landforms at present and provided a legacy in areas that no longer have glacial ice. During the Quaternary period glaciers covered up to one third of the earth's surface whereas they occupy ...
