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. Both ice sheets are also very thick, as ...

The Cordilleran ice sheet was a major ice sheet that periodically covered large parts of North America during glacial periods over the last ~2.6 million years. The ice extent covered almost all of the continental shelf north of the Strait of Juan de Fuca and south from approximately the southwestern third of the Yukon Territory.

In glaciology, an ice sheet (Danish: «Indlandsis», meaning «inland ice»), usually called continental glacier and sometimes ice shell or ice layer, is a large mass of glacier ice with an average thickness of over 2 km that covers a large continental area in the polar regions of the Earth.

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]

The Antarctic ice sheet is one of the two continental glaciers of the world. It covers 98% of the Antarctic continent, and is the largest single block of ice in the world, with at least 14 million km² and contains 30 million km³ of ice.

The Greenland Ice Sheet (Greenlandic: Sermersuaq) is a large ice sheet that covers about 80% of the surface of Greenland, part of Denmark. It is the second largest in the world, after the Antarctic ice sheet.

2025年1月14日 · Ice sheet, any glacier that extends in continuous sheets, moving outward in all directions, whose area exceeds more than 50,000 square km (19,000 square miles). In general, such expanses of frozen water are called ice sheets if they are the size of Antarctica or Greenland and ice caps if they are

The Antarctic ice sheet is a continental glacier covering 98% of the Antarctic continent, with an area of 14 million square kilometres (5.4 million square miles) and an average thickness of over 2 kilometres (1.2 mi).

2024年4月14日 · English: An Ice sheet is a mass of glacier ice that covers surrounding terrain and is greater than 50,000 km2 (19,000 sq mi), thus also known as continental glacier. The only current ice sheets are in Antarctica and Greenland; during the last glacial period at Last Glacial Maximum (LGM) the Laurentide ice sheet covered much of North America ...
