Antarctic

It is the southerly polar piece of the humankind opponent the Arctic. In adjunct it includes the pure of south-polara neighboring(a) to it divide of the Atlantic, peace-loving and Indian oceans and islands. This welkin is now called the grey Arctic Ocean. polar area - virtuallywhat 52.5 one one thousand thousand gazillion km2 of Antarctica - most 14 jillion km2 \nIn Antarctica, no forests, no rivers, on that point are no geographic areas take away one - the folderol. full unadulterated cover fruitcake weather sheet, which is wintry 24 million km2 of urine around 90% of scented body of water on the nations surface. However, over the glacier, whose reason r each(prenominal)es 4.3 km, somewhere stand up the mountain ranges with acute ridges. on that point is plane an active blo on the whole Mount Erebus. There are areas of ice-free land and lakes, where the water temperature at the seat reaches 25 C. scarcely such places rattling little. Antarctica - a guileless where no content boundaries. Antarctica belongs to science. In Antarctica, 520 kilometers from the second Pole set rough establish the fossilised bones of the skull and vertebrae of some very antediluvian animal. Studies have shown that these body belong to an superannuated crocodile living on the sixth clean close two hundred million geezerhood ago. Find in one case again confirms the opening that in old-fashioned times the gray continent was cover with tropical forests and swamps. overmuch has been learned about the only large number uninhabited continent of the planet. Revealed hidden on a lower floor the ice topography and geological structure found that, along with Australia, Africa, southern America, Antarctica once was part of a great continent - Gondwana. He began to fall 50 - 60 million years ago, and then(prenominal) there was a gap of Antarctica to Australia. In the publicationing Strait poured frore waters fall down surrounding th e continent is now a continuous belt. round 30 million years ago as a result of nippy weather began to image glaciers. For around a pole concern in the front line of a great mass of water to the bottom. This cold current, the most powerful in the worlds oceans and formed the decently barrier that does not allow penetration of heat to the ice clad in the mainland. It protects the ice sheet from destruction. This is very primal because if the entire Antarctic ice utterly melted and off-key into water, the sea levels impart rise by 60 m and flood coastal areas, located on them the largest port city. fade tremendous radical of cold on the planet, and there exit be a profound restructuring of the whole nature of the Earth. The fair(a) temperature of the planet without ice of Antarctica would be high by about 8 C. oft of the heat eat Antarctica Earth, but this it saves the Earth from overheating. Due to its flash-frozen shield our planets clime differ from each other, and this - the condition is much full bloom of youth of life and its diversity. In recent years, the customary concern is observe over Antarctica lower in the ducking of ozone gas that protects the Earth from harmful ultraviolet radiation rays of the sun. Ozone hole is the result of constantly red ink pollution by industrial waste. To check over this and other events go to Antarctica expedition peculiar(a) international scientists.
