Ninety-eight percent of the continent -- which is about the size of USA and Mexico combined -- is covered by an ice sheet. Because of its geography, glaciers -- defined as ice that moves under its own weight -- form in the sheet, and are calved off to form ice tongues. Eventually, these break off and become icebergs.

Alpine glaciers, even though they move, are confined to mountain valleys, which in most instances had previously been a stream valley. Continental ice sheets exist on a much larger scale. These huge masses flow out in all directions from one or more centers of the land. They cover the entire continent, hence the name, and extend out toward the sea. Only two exist today: Greenland and Antarctica.
