EARTH SCIENCE > TERRESTRIAL HYDROSPHERE > GLACIERS/ICE SHEETS > ICE SHEETS
A continuous sheet of land ice that covers a very large area and moves outward
in many directions. This type of ice mass is so thick as to mask the land
surface contours, in contrast to the smaller and thinner highland ice. The
continental glacier of Greenland is sometimes called the Inland Ice. This term
is often used to describe the great ice masses that characterized the ice ages.
