Is there a lake under Antarctica?

Lake Vostok (Russian:, ozero Vostok) is the largest of Antarctica’s almost 400 known subglacial lakes. Lake Vostok is located at the southern Pole of Cold, beneath Russia’s Vostok Station under the surface of the central East Antarctic Ice Sheet, which is at 3,488 m (11,444 ft) above mean sea level.

What are thick sheets of ice called?

Ice sheets contain about 99% of the freshwater on Earth, and are sometimes called continental glaciers. As ice sheets extend to the coast and over the ocean, they become ice shelves. A mass of glacial ice covering less area than an ice sheet is called an ice cap.

The Ross Ice Shelf is the largest floating slab of ice on Earth, at 480,000 square kilometres. The ocean cavity it conceals extends 700km south from Antarctica’s coast and remains largely unexplored. We know ice shelves mainly melt from below, washed by a warming ocean.

Where is the deepest lake in the world?

Lake Baikal, in Siberia, holds the distinction of being both the deepest lake in the world and the largest freshwater lake, holding more than 20% of the unfrozen fresh water on the surface of Earth.

Lake Tanganyika, second largest of the lakes of eastern Africa. It is the longest freshwater lake in the world (410 miles [660 km]) and the second deepest (4,710 feet [1,436 metres]) after Lake Baikal in Russia.

How thick is the ice on Lake Vostok?

The magnificent ice sheet that blankets Antarctica holds 6.4 million cubic miles (27 million cubic kilometers) of frozen water. From top to bottom, it’s over 2.2 miles (3.5 kilometers) thick in some places.

What would Antarctica be like without ice?

The weather will be fairly harsh even without the ice (six month “seasons” of summer sun and winter darkness), and Antarctica gets little precipitation, so will be quite dry and arid.
