Antarctica is Earth's southernmost continent. It contains the geographic South Pole and is situated in the Antarctic region of the Southern Hemisphere, almost entirely south of the Antarctic Circle, and is surrounded by the Southern Ocean. At 14,000,000 square kilometres (5,400,000 square miles), it is the fifth-largest continent. For comparison, Antarctica is nearly twice the size of Australia. About 98% of Antarctica is covered by ice that averages 1.9 km (1.2 mi; 6,200 ft) in thickness,[5] which extends to all but the northernmost reaches of the Antarctic Peninsula.
Antarctica, on average, is the coldest, driest, and windiest continent, and has the highest average elevation of all the continents.[6]Antarctica is a desert, with annual precipitation of only 200 mm (8 in) along the coast and far less inland.[7] The temperature in Antarctica has reached −89.2 °C (−128.6 °F) (or even −94.7 as measured from space[8]), though the average for the third quarter (the coldest part of the year) is −63 °C (−81 °F). Anywhere from 1,000 to 5,000 people reside throughout the year at the research stations scattered across the continent. Organisms native to Antarctica include many types of algae, bacteria, fungi, plants, protista, and certain animals, such as mites, nematodes, penguins, seals and tardigrades. Vegetation, where it occurs, is tundra.

Antarctica, fifth in size among the world’s continents. Its landmass is almost wholly covered by a vast ice sheet.
Lying almost concentrically around the South Pole, Antarctica—the name of which means “opposite to the Arctic”—is the southernmost continent, a circumstance that has had momentous consequences for all aspects of its character
It covers about 5.5 million square miles (14.2 million square km), and would be essentially circular
The continental ice sheet contains approximately 7 million cubic miles (29 million cubic km) of ice, representing about 90 percent of the world’s total. The average thickness is about 1.5 miles (2.45 km).
Because of this vast ice, the continent supports only a primitive indigenous population of cold-adapted land plants and animals. The surrounding sea is as rich in life as the land is barren.
All its mountain regions have been mapped and visited by geologists, geophysicists, glaciologists, and biologists
The continent was ice-free during most of its lengthy geologic history, and there is no reason to believe it will not become so again in the probably distant future...
