Types of ice mass 0.0 / 5 ? GeographyGlaciated LandscapesASEdexcel Created by: AlishaHaley2017Created on: 14-06-17 08:22 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 Describe a cirque glacier. 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. 8 of 22 How large is an ice sheet? More than 50,000 km 2 9 of 22 How large is an ice cap? Less than 50,000 km 2 10 of 22 How large is an ice field? Less than 50,000 km 2 11 of 22 How large is a valley glacier? 5-1500 km 2 12 of 22 How large is a piedmont glacier? 3-1000 km 2 13 of 22 How large is a cirque glacier? 0.5-10km 2 14 of 22 How large is an ice shelf? 10,000-100,000 km 2 15 of 22 Give an example of an ice sheet. Antarctica and Greenland. 16 of 22 Give an example of an ice cap. Austfonna on Svalbard, Vatnajokull in Iceland 17 of 22 Give an example of an ice field.
