Glacier

Posted: 30 April 2001

Large, usually moving mass of ice formed in high mountains or in high latitudes where the rate of snowfall is greater than the melting rate of snow. Glaciers can be divided into four well-defined types - alpine, piedmont, ice cap, and continental - according to the topography and climate of the region in which the glacier was formed.
