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
Antarctica lies concentrically around the South Pole, its landmass almost wholly covered by a vast ice sheet averaging 6,500 ft (2,000 m) thick. It is divided into two subcontinents: East Antarctica, consisting mainly of a high, ice-covered plateau, and West Antarctica, consisting largely of an archipelago of mountainous islands covered with ice.
L''Antarctique (prononcé / ɑ̃. t a ʁ k. t i k /, ou aussi / ɑ̃. t a ʁ. t i k / Écouter), parfois appelé « le Continent Austral » ou « le Continent Blanc » [b], est le continent le plus méridional de la Terre.Situé autour du pôle Sud, il est entouré des mers de Ross et de Weddell et, suivant les classifications, des océans Atlantique, Indien et Pacifique ou du seul océan Austral.

Here we report the recovery of a deep ice core from Dome C, Antarctica, that provides a climate record for the past 740,000 years. For the four most recent glacial cycles, the data agree well with
Antarctica: as remote as it gets on Earth. Concordia research station is a collaboration between the French Polar Institute and the Italian Antarctic programme. It is one of only three bases that is inhabited all year long, and is located at the mountain plateau called Dome C. Pictured in this image is the astronomical observatory near the base

McMurdo Station (77°51''S, 166°40''E), the main U.S. station in Antarctica, is a coastal station at the southern tip of Ross Island, about 3,864 km (2,415 miles) south of Christchurch, New Zealand, and 1,360 km (850 miles) north of the South Pole. The original station was built in 1955 to 1956 for the International Geophysical Year.
Climate. the coldest, windiest, and driest continent on Earth; severe low temperatures vary with latitude, elevation, and distance from the ocean; East Antarctica is colder than West Antarctica because of its higher elevation; Antarctic Peninsula has the most moderate climate; higher temperatures occur in January along the coast and average slightly below

Surface temperature of Antarctica in winter and summer from the European Centre for Medium-Range Weather Forecasts. The climate of Antarctica is the coldest on Earth.The continent is also extremely dry (it is a desert [1]), averaging 166 mm (6.5 in) of precipitation per year. Snow rarely melts on most parts of the continent, and, after being compressed, becomes the glacier ice

The geography of Antarctica is dominated by its south polar location and, thus, by ice.The Antarctic continent, located in the Earth''s southern hemisphere, is centered asymmetrically around the South Pole and largely south of the Antarctic Circle is washed by the Southern (or Antarctic) Ocean or, depending on definition, the southern Pacific, Atlantic, and Indian Oceans.
The Antarctic ice sheet is a continental glacier covering 98% of the Antarctic continent, with an area of 14 million square kilometres (5.4 million square miles) and an average thickness of over 2 kilometres (1.2 mi) is the largest of Earth''s two current ice sheets, containing 26.5 million cubic kilometres (6,400,000 cubic miles) of ice, which is equivalent to 61% of all fresh water on Earth.
Mystery of Antarctica: One of the most compelling mysteries about our changing planet over the past five years has been the sudden and dramatic drop in ice surrounding Antarctica. Prior to 2015, the ice that encased the frozen continent defied expectations and bucked the trend of other cold environments around the planet by actually growing in
This happens because the earth is round,and a map is flat. If we take a ball’s outer layer and spread it out flat it gets crumpled at the ends. The same happens with maps and Greenland looks much bigger than Africa though it isn’t. The same goes for Antarctica. Its because of the projection type used to depict the earth surface.
The truth is that expeditions to Antarctica are nearly impossible, extremely costly, and very dangerous. Without adequate equipment, a human being wouldn’t last very long on this icy continent. Ok, the Pyramids aren’t the only thing on Antarctica, and apparently, there are more structures.
