In glaciology, an ice sheet, also known as a continental glacier, [2] is a mass of glacial ice that covers surrounding terrain and is greater than 50,000 km 2 (19,000 sq mi). [3] The only current ice sheets are the Antarctic ice sheet and the Greenland ice sheet. Ice sheets are bigger than ice shelves or alpine glaciers.
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.
10 lis 2023 · An ice sheet is a mass of glacial ice more than 50,000 square kilometers (19,000 square miles). Ice sheets contain about 99% of the fresh water on Earth, and are sometimes called continental glaciers. As ice sheets extend to the coast and over the ocean, they become ice shelves.
An ice sheet is a mass of glacial land ice that covers more than 50,000 square kilometers. Antarctica and Greenland hold the Earth’s two ice sheets, and both lose hundreds of gigatonnes (109 tonnes) of ice mass each year to melting (Fig 3.3.1.1).
28 paź 2012 · Glacial ice covers around 10% of the Earth's continents 1 (Table 1). Surface melting occurs annually in up to ∼ 5% of the surface area of glaciers and ice sheets 2, 3, 4, 5. The liquid...
Ice sheets contain enormous quantities of frozen water. If the Greenland Ice Sheet melted entirely, scientists estimate that sea level would rise about 7.4 meters (23 feet). If the Antarctic Ice Sheet melted, sea level would rise by about 60 meters (200 feet).
An ice sheet is a mass of glacial land ice, extending more than 50,000 square kilometers (20,000 square miles). Ice sheets can cover underlying canyons and mountain ranges. During the last ice age, ice sheets also covered much of North America and Scandinavia.
