24 lis 2023 · Continental glaciers (a.k.a. ice sheets) cover vast areas of land and only exist now in extreme polar regions, including Antarctica and Greenland (Figure 4.2.1). Alpine glaciers (a.k.a. valley glaciers) originate on mountains, mostly in temperate and polar regions, but even in tropical regions if the mountains are high enough.
Past ice sheets have retreated rapidly, raising global sea level at rates >1 cm per year, with marine ice sheets collapsing and terrestrial ice sheets retreating in a more gradual...
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.
An ice sheet is a continental-scale body of ice that flows under its own weight towards the ocean. Ice sheets form over thousands of years as snow accumulates from year to year, gaining mass and compressing older layers into ice.
