A glacier is an accumulation of ice, air, water, and rock debris or
sediment. It is a large enough quantity of ice to flow with gravity due to
its own mass. The ice can be as large as a continent, such as the ice
sheet covering Antarctica; or, it can fill a small valley between two
mountains, such as a valley glacier. "Glacial landforms/processes"
refers to the erosional or depositional processes of glaciers and the
landforms (e.g., drumlins, cirques, fjords) that result.
