Gradient. Just like with coasts and rivers, glaciers also have the ability to erode, transport and deposit material. Glaciers shape the land through processes of, - as the glacier moves downhill, rocks that have been frozen into the base and sides of the glacier scrape the rock beneath. Glaciers form whenever snowfall exceeds snowmelt year after year. Nearly all glacially scoured erosional landforms bear the tool-marks of glacial abrasion provided that they have not been removed by subsequent weathering.

How much of the Earth do glaciers cover? Abrasion . In addition, large expansions of present-day glaciers have recurred during the course of Earth history. Scouring creates a variety of features. The highest of these sides is called the headwall. The scientific study of glacial processes and landforms formed in front of, beneath and along the margins of valley glaciers, ice sheets and other ice masses on the Earth’s surface, both on land and in ocean basins, constitutes glacial geomorphology. There are several types of moraine: (1) lateral moraine: forms along each side of a glacier (2) medial moraine: if two glaciers with lateral morains join, a medial moraine may form. Glacial Depositional Landforms First, at the base of a glacier, large amounts of loose rock and sediment are incorporated into the moving glacial ice by partial melting and refreezing.
