Types of ice mass

Name 5 types of ice mass.
Ice sheet, ice cap, ice field, valley glacier, cirque glacier.
1 of 22
Describe an ice sheet.
Large, dome-shaped ice masses that completely submerge underlying topography and are many kilometres thick.
2 of 22
Describe an ice cap.
A smaller version of an ice sheet, with its high point corresponding to the high point of submerged mountains beneath the ice.
3 of 22
Describe an ice field.
Ice covering a mountain plateau, but not thick enough to bury all of the topography or extend beyond the high altitude area.
4 of 22
Describe a valley glacier.
A long tongue of ice confined between valley sides and terminating in the valley or at the sea. Outlet glaciers drain ice caps and ice fields.
5 of 22
Describe a piedmont glacier.
It is valley glacier which extends beyond the end of a mountain valley into a flatter area and spreads out like a fan.
6 of 22

A smaller glacier occupying a hollow in a mountain side and circular in shape (also called a corrie glacier).
7 of 22
Describe an ice shelf.
Large area of floating glacier ice extending from the coast where several glaciers have reached the sea and coalesce.
