2. Ice sheet - Wikipedia

   en.wikipedia.org/wiki/Ice_sheet

   Greenland ice sheet as seen from space. An ice sheet is a body of ice which covers a land area of continental size - meaning that it exceeds 50,000 km 2. [4] The currently existing two ice sheets in Greenland and Antarctica have a much greater area than this minimum definition, measuring at 1.7 million km 2 and 14 million km 2, respectively.

3. Laurentide ice sheet - Wikipedia

   en.wikipedia.org/wiki/Laurentide_ice_sheet

   The Cordilleran ice sheet covered up to 1,500,000 square kilometres (580,000 sq mi) at the Last Glacial Maximum. [11] The eastern edge abutted the Laurentide ice sheet. The sheet was anchored in the Coast Mountains of British Columbia and Alberta, south into the Cascade Range of Washington. That is one and a half times the water held in the ...

4. Greenland ice sheet - Wikipedia

   en.wikipedia.org/wiki/Greenland_ice_sheet

   The Greenland ice sheet is an ice sheet which forms the second largest body of ice in the world. It is an average of 1.67 km (1.0 mi) thick and over 3 km (1.9 mi) thick at its maximum. [ 2 ] It is almost 2,900 kilometres (1,800 mi) long in a north–south direction, with a maximum width of 1,100 kilometres (680 mi) at a latitude of 77°N , near ...

5. Glacier morphology - Wikipedia

   en.wikipedia.org/wiki/Glacier_morphology

   [4] [5] [6] As ice sheets expand over the ocean, they become ice shelves. [6] Ice sheets contain 99% of all the freshwater ice found on Earth, and form as layers of snowfall accumulate and slowly start to compact into ice. [5] There are only two ice sheets present on Earth today: the Antarctic ice sheet and the Greenland ice sheet.

6. Moulin (geomorphology) - Wikipedia

   en.wikipedia.org/wiki/Moulin_(geomorphology)

   Water from moulins may help lubricate the base of the glacier, affecting glacial motion. Given an appropriate relationship between an ice sheet and the terrain, the head of water in a moulin can provide the power and medium with which a tunnel valley may be formed.
