Types of glaciers. There are two primary types of glaciers: : Ice sheets are dome-shaped glaciers that flow away from a central region and are largely unaffected by underlying topography (e.g., Greenland and Antarctic ice sheets); : glaciers in mountains that flow down valleys.When two or glaciers meet and merge at the base of mountains, the new glacier is called a piedmont glacier. If the piedmont glacier flows to the sea, it's called a tidewater glacier.1) cirque glacier-glacier confined by a valley; forms in a cirque (semicircular basin at head of valley formed by plucking of bedrock by glacier moving down hill). 2) valley glacier-form in a valley. 3) ice caps-cover mountain tops.ypes of glaciers.
