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 that makes up the ice sheet. Weather fronts rarely penetrate far into the ...
The climate of present-day Antarctica does not allow extensive vegetation to form. [126] A combination of freezing temperatures, poor soil quality, and a lack of moisture and sunlight inhibit plant growth, causing low species diversity and limited distribution. The flora largely consists of bryophytes (25 species of liverworts and 100 species ...
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. It is washed by the Southern (or Antarctic) Ocean or, depending on definition, the southern ...
Climate change in Antarctica. Antarctic surface ice layer temperature trends between 1981 and 2007, based on thermal infrared observations made by a series of NOAA satellite sensors. Climate change caused by greenhouse gas emissions from human activities occurs everywhere on Earth, and while Antarctica is less vulnerable to it than any other ...
The geology of Antarctica covers the geological development of the continent through the Archean, Proterozoic and Phanerozoic eons. The geological study of Antarctica has been greatly hindered by the fact that nearly all of the continent is continuously covered with a thick layer of ice. However, techniques such as remote sensing have begun to ...
Website. Amundsen-Scott South Pole Station. The Amundsen–Scott South Pole Station is a United States scientific research station at the South Pole of the Earth. It is the southernmost point under the jurisdiction (not sovereignty) of the United States. The station is located on the high plateau of Antarctica at 9,301 feet (2,835 m) above sea ...
The high, flat, and cold environment of the Antarctic Plateau at Dome C Surface of Antarctic Plateau, at 150E, 77S. The Antarctic Plateau, Polar Plateau or King Haakon VII Plateau is a large area of East Antarctica that extends over a diameter of about 1,000 kilometres (620 mi), and includes the region of the geographic South Pole and the Amundsen–Scott South Pole Station.
