Ice sheets

Deutsch: Als de:'''Eisschild''' oder '''Inlandseis''' bezeichnet man einen ausgedehnten, festes Land bedeckenden Gletscher mit einer Fläche von mehr als 50.000 km². Der Eisschild begräbt das vorhandene Relief nahezu vollständig unter sich. Die Bewegung des Eises wird auch nur unwesentlich von diesem beeinflusst.

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, the Weichselian ice sheet covered northern Europe and the Patagonian Ice Sheet covered southern South America.
