Seven sovereign states – Argentina, Australia, Chile, France, New Zealand, Norway, and the United Kingdom – have made eight territorial claims in Antarctica.These countries have tended to place their Antarctic scientific observation and study facilities within their respective claimed territories; however, a number of such facilities are located outside of the area claimed by their ...
A 437,000-square-kilometre (169,000 sq mi) triangle of central Antarctica converging on the South Pole was named Queen Elizabeth Land in December 2012, in honour of the Diamond Jubilee of Elizabeth II. [7] [8] Over 99 per cent of the territory's land surface is covered by a permanent ice sheet, up to about 5,000 metres (16,000 ft) thick. [9]
A map of the Antarctic region, including the Antarctic Convergence and the 60th parallel south The Antarctic Plate. The Antarctic (/ æ n ˈ t ɑːr t ɪ k,-k t ɪ k /, US also / æ n t ˈ ɑːr t ɪ k,-k t ɪ k /; commonly / æ ˈ n ɑːr t ɪ k /) [Note 1] is a polar region around Earth's South Pole, opposite the Arctic region around the North Pole.
Most of Antarctica is covered by the Antarctic ice sheet, with an average thickness of 1.9 km (1.2 mi). Antarctica is, on average, the coldest, driest, and windiest of the continents, and it has the highest average elevation. It is mainly a polar desert, with annual precipitation of over 200 mm (8 in) along the coast and far less inland.
The Antarctic Peninsula and its nearby islands are considered to have the mildest living conditions in Antarctica. The island's climate is strongly influenced by the surrounding ocean. [18] Under the Köppen system, it is one of the few locations in Antarctica classified as a tundra climate rather than an ice cap climate. [19]
Mount Erebus (/ ˈ ɛr ɪ b ə s /) is the southernmost active volcano on Earth, located on Ross Island in the Ross Dependency in Antarctica.With a summit elevation of 3,792 metres (12,441 ft), it is the second most prominent mountain in Antarctica (after Mount Vinson) and the second-highest volcano in Antarctica (after the dormant Mount Sidley).
Marie Byrd Land (MBL) is an unclaimed region of Antarctica.With an area of 1,610,000 km 2 (620,000 sq mi), it is the largest unclaimed territory on Earth. It was named after the wife of American naval officer Richard E. Byrd, who explored the region in the early 20th century.
Antarctica's two flowering plant species, the Antarctic hair grass (Deschampsia antarctica) and Antarctic pearlwort (Colobanthus quitensis) are found on the northern and western parts of the Antarctic Peninsula, including offshore islands, where the climate is relatively mild. Lagotellerie Island in Marguerite Bay is an example of this habitat.
