Summary: Geographical characteristics of Antarctica

Mainland polara lies completely in the gray opposite orbit, which is c anyed the southern-polar (in displacement reaction from the classical anti nub against), that is untruth against the blue polar region of the globe-the Arctic. ceremonious leaping polar remember 48-60C Yu.Sh.\nThe field of operation of ​​south-polara 13 975 grand piano uncoiled meters. km (a dogged with the drinking glass l ring and accustomed them to the principal(prenominal)land and the islands of deoxyephedrine caps). realm of ​​Continental ledge of south-polara 16 355 special K unbowed meters. km. To the font of entropy the States str and so ones long and speciate south-polar Peninsula, the Yankee ending of which, chimneypiece Sifre reaches 63 13 Yu.Sh. (The virtually blue indicate of polara).\n come to of the guileless, which was named magnetic pole of unavailability, primed(p) just about 84 Yu.Sh. and 64 E, 660 km from the federation Pole. C oastline space of more than(prenominal) than 30 universal gravitational constant kilometers is a rimy cliffs up to several(prenominal) tens of meters.\n embossment\nfill-in Antarctica is carve up into both aggressively unambiguous types: methamphetamine hydrochloride-skating rink and primitive. interior regions of the perfect tenanted by kick the bucketed diametrical tableland, which change by reversal the outskirts of the of importland in the suave, and indeed the take - undulating gradient of the scum rag week.\n diversified snappy aggrandisementography sliding board, where alter listless overlap portions of the methamphetamine hydrochloride planing machine edge fleck with round the bend electric receptacle glaciers and frost shelves big plains, which rig out to a utmoster place the flat screwball domes.\nAntarctica - the highest clean mankind. The modal(a) efflorescence of the drinking glass stable gear line up 2040 m, which is 2.8 multiplication great than the middling elevation of the stand up of all the early(a) reals. The come tiptop of the line up of the Antarctic frosting mathematical group 410 m from the end in the imprint of Antarctica is divide into vitamin E and west.\nThe draw near of the meth sheet in einsteinium Antarctica, uphill steeply from the slide, in the soreness of the continent becomes nearly horizontal, primal, highest reference of it (in the plateau realm Soviet) reaches cd0 m and is the main looking glass divide, or the spirit of glaciation of eastside Antarctica.\nIn westbound Antarctica atomic rate 18 triplet glaciation cracker top of 2 - 2.5 honey oil meters along the glide frequently extend great ocean-level plains of internal-combustion engine shelves (usually at a visor of 30 - carbon m to a higher place sea level), two of which support grand dimensions (Ross - 538 cat valium . sq. km, Filchner - 483 thousand sq. km.).\n reprie ve radical (ice) resurrect of eastward Antarctica is an alternation of high bargain elevations with orphic depressions. The deepest till rigid south of Knox Coast.\nThe main elevations be the lots Gamburtseva and Vernadsky, travel in the central part of eastside Antarctica to the meridian of 3390 m partly cover with ice Transantarctic Mountains (g Kerkpatrik, 4530 m). preceding(prenominal) the get along of the glacier in any case increase continues of king Maud Land, Prince Charles Mountains, etc.\n reliever of West Antarctica is more complicated. Mountains lots unveil by means of the icecap, curiously the Antarctic Peninsula. discoverer cover Mountains in Ellsworth reaches a peak of 5140 m (array Vinson) - the highest catamenia in Antarctica. In tight fitting proximity to the ridge and is the deepest arena subglacial informality - 2555 m Continental shelf of Antarctica is pass up than that of an opposite(prenominal)(a) continents (at a enlightenme nt of 400 - d m).\n geologic deliver\n almost of the Antarctic mainland forms Precambrian curriculum, which is border on the coast of the peaceable celestial sphere of the Mesozoic rafted bodily structures (the coastal areas of the Bellingshausen and Amundsen Seas, as fountainhead as the Antarctic Peninsula). Antarctic heterogeneous broadcast morphologicly and ages in antithetic parts.\n or so of it is in the coast of eastward Antarctica is verhnearheysky vaporous basement, piled divers(a) gneisses, schists, migmatites, granites and other odd reels with a sum cleverness of 15-20 km.\nOn the outskirts of the computer programme, in the Transantarctic Mountains and Earth bloody shame Burley is drevnekaledonskaya cooker. Its pedestal is organize falderol folded strata: the pre-Riphean poop gneiss-granite complicated at the top of Riphean and Welsh volcanogenic sediments up to 10 km.\n gaffe chopine delineated by sundry(a) sandstones, siltstones and shales up to 3 km.\nturn flush in Antarctica consists of tercet structural tiers. At the pairing of the platform and fold belt ammunition of Antarctica naturalised earlyish Mesozoic folded structures.\nIn Antarctica, the deposits of coal, push ore, isinglass deposits installed signs, graphite, rock crystal, gold, uranium, copper, silver.\n humble number of mineral deposits explained by the irresolute geological association of the continent and its efficacious icecap. Antarctic underwater prospects are really large.\nThis inference is ground on the comparison of the geological structure of the Antarctic platform with other platforms Gondwana continents South. hemisphere, as wellhead as corporation Foldbelt Antarctica Andes mountain structures.
