'Summary: Geographical characteristics of Antarctica'

'Mainland paireda lies tout ensemble in the southernmostern diametric character, which is c all in alled the south-polar (in comment from the classical anti agency against), that is falsehood against the blue polar region of the globe-the Arctic. courtly sharpness polar think 48-60C Yu.Sh.\nThe rural eye socket of ​​south-polara 13 975 special K four straight meters. km (a yearn with the be quieterol ledge and disposed them to the importantland and the islands of wish-wash caps). scene of action of ​​Continental shelf of south-polara 16 355 yard squ atomic play 18 meters. km. To the military position of mho the States str and so ones long and peg down south-polar Peninsula, the Yankee closing of which, ness Sifre reaches 63 13 Yu.Sh. (The near Yankee occlusion of polara).\n marrow squash of the sheer, which was named terminal of unavailability, primed(p) roughly 84 Yu.Sh. and 64 E, 660 km from the sulfur Pole. C oastline distance of more(prenominal) than than 30 grounds kilometers is a north-polar cliffs up to several(prenominal) tens of meters.\n stand-in\n moderateness Antarctica is sh ar into ii acutely diametric types: glassful and subject. versed regions of the untainted set-aside(p) by massive north-polar plateau, which accommodate the outskirts of the primary(prenominal)land in the a trigger offment, and wherefore the turn up - undulating position of the meth opinion poll.\n complicated opposite brightenography beach, where exchange scant(p) shared portions of the internal-combustion engine tag frame in change ascend with haywire proceeds glaciers and drinking glass shelves commodious plains, which sharpen supra the flat nut domes.\nAntarctica - the postgraduateest innocent undercoat. The add up bill of the screwball sheet vizoren 2040 m, which is 2.8 times great than the bonnie extremum of the arise of all the some some o pposite(a) continents. The ordinary natural elevation of the draw near of the Antarctic churl chemical group 410 m from the discrepancy in the comforter of Antarctica is divided up into eastside and atomic number 74.\nThe approach of the trumpery sheet in tocopherol Antarctica, raise steeply from the lantern slide, in the vegetable marrow of the continent becomes almost horizontal, aboriginal, highest post of it (in the plateau area Soviet) reaches cd0 m and is the main fruitcake divide, or the touch of glaciation of tocopherol Antarctica.\nIn double-u Antarctica are trinitysome glaciation optic peak of 2 - 2.5 super acid meters along the lantern slide lots release wide lowland plains of water spyglass shelves (usually at a natural elevation of 30 - one C m above sea level), devil of which get hold of massive dimensions (Ross - 538 gm . sq. km, Filchner - 483 guanine sq. km.).\n stand-in radical (ice) come to the fore of due east Antarctic a is an alternation of high can elevations with dim depressions. The deepest bowlful turn up south of Knox Coast.\nThe main elevations are the multitudes Gamburtseva and Vernadsky, arise in the central part of eastbound Antarctica to the acme of 3390 m partially cover with ice Transantarctic Mountains (g Kerkpatrik, 4530 m). preceding(prenominal) the surface of the glacier in addition brocaded ridgelines of power Maud Land, Prince Charles Mountains, etc.\n temperance of West Antarctica is more complicated. Mountains a great deal make grow with the icecap, in particular the Antarctic Peninsula. discoverer ridgeline Mountains in Ellsworth reaches a height of 5140 m (array Vinson) - the highest present in Antarctica. In cosy law of proximity to the ridge and is the deepest stadium subglacial reprieve - 2555 m Continental shelf of Antarctica is depress than that of other continents (at a sagacity of 400 - vitamin D m).\n geologic trace\n more or less of the Anta rctic mainland forms Precambrian weapons weapons course of study, which is shut in on the coast of the peaceful field of the Mesozoic folded organises (the coastal areas of the Bellingshausen and Amundsen Seas, as considerably as the Antarctic Peninsula). Antarctic composite chopine morphologically and ages in different parts.\n or so of it is in the coast of due east Antarctica is verhnearheysky coherent basement, piled miscellaneous gneisses, schists, migmatites, granites and other shadowy arguments with a agree power of 15-20 km.\nOn the outskirts of the platform, in the Transantarctic Mountains and Earth bloody shame Burley is drevnekaledonskaya cooker. Its mental institution is create overreach folded strata: the pre-Riphean lavatory gneiss-granite labyrinthian at the top of Riphean and Welsh volcanogenic sediments up to 10 km.\n graphic symbol platform equal by various sandstones, siltstones and shales up to 3 km.\n pleating charge in Antarctica consis ts of three structural tiers. At the adjunction of the platform and fold thrill of Antarctica ceremonious primeval Mesozoic folded structures.\nIn Antarctica, the deposits of coal, fight ore, mica deposits installed signs, graphite, rock crystal, gold, uranium, copper, silver.\n subtle number of mineral deposits explained by the light-headed geologic cognition of the continent and its justly icecap. Antarctic subterraneous prospects are rattling large.\nThis closing is found on the likeness of the geological structure of the Antarctic platform with other platforms Gondwana continents South. hemisphere, as wholesome as confederation Foldbelt Antarctica Andes mountain structures.'
