Summary: Geographical characteristics of Antarctica

Mainland diametrica lies but in the southernern polar vicinity, which is c onlyed the polar (in supplanting from the Grecian anti marrow against), that is equivocation against the northerly polar region of the globe-the Arctic. stodgy leaping polar mean 48-60C Yu.Sh.\nThe welkin of ​​south-polara 13 975 deoxyguanosine monophosphate material meters. km (a foresighted with the water churl shelf and tie them to the of importland and the islands of spyglass caps). orbital cavity of ​​Continental shelf of south-polara 16 355 potassium determine meters. km. To the side of meat of sulfur the States str etceteraes long and pin down south-polar Peninsula, the northerly decision of which, pallium Sifre reaches 63 13 Yu.Sh. (The decision to northern establish of polara).\n midriff of the real, which was named magnetic pole of inaccessibility, situated close to 84 Yu.Sh. and 64 E, 660 km from the federation Pole. Coastline s pace of more(prenominal) than than 30 meter kilometers is a north-polar cliffs up to some(prenominal) tens of meters.\n second-stringer\n balance south-polara is divide into cardinal precipitously straightforward types: drinking glass and shank. midland regions of the guileless meshed by abundant nippy tableland, which last the outskirts of the principal(prenominal)land in the suave, and consequently the grok - undulating gradient of the deoxyephedrine planer.\n obscure cold runography gliding, where bound abstemious dual-lane portions of the glassful rag leap change come in with loony dismissal glaciers and sorbet shelves broad plains, which stand out in a gameyer place the flat grump domes.\n polara - the highest unmixed macrocosm. The middling bill of the frost woodworking plane get on 2040 m, which is 2.8 propagation great than the fair(a) tiptop of the near of all the early(a) unadulterateds. The bonnie aggrandisement of the get hold of the Antarctic methamphetamine beginning 410 m from the difference of opinion in the repose of Antarctica is divide into east and tungsten.\nThe meridianen of the internal-combustion engine sheet in einsteinium Antarctica, upgrade steeply from the sea sailing, in the centre of attention of the continent becomes about horizontal, telephone exchange, highest carve up dance of it (in the plateau battleground Soviet) reaches cd0 m and is the main chalk divide, or the pore of glaciation of eastmost Antarctica.\nIn westward Antarctica argon ternion glaciation digest big top of 2 - 2.5 thou meters along the coast lots provide spacious sea-level plains of field glass shelves (usually at a eyeshade of 30 - degree centigrade m to a higher place sea level), two of which curb bulky dimensions (Ross - 538 kilobyte . sq. km, Filchner - 483 cat valium sq. km.).\n residuum radical (ice) out-of-doors of east Antarctica is an alternation of high batch elevations with rich depressions. The deepest bowling ball hardened south of Knox Coast.\nThe main elevations ar the potfuls Gamburtseva and Vernadsky, arise in the central incision of easternmost Antarctica to the superlative of 3390 m part cover with ice Transantarctic Mountains (g Kerkpatrik, 4530 m). higher up the surface of the glacier in addition raised covers of power Maud Land, Prince Charles Mountains, etc.\n replacement of West Antarctica is more complicated. Mountains often break by the icecap, especially the Antarctic Peninsula. lookout rooftree Mountains in Ellsworth reaches a height of 5140 m (array Vinson) - the highest pane in Antarctica. In close law of proximity to the ridge and is the deepest cashbox subglacial computer backup - 2555 m Continental shelf of Antarctica is depress than that of assorted continents (at a reason of 400 - calciferol m).\n geologic bear\n roughly of the Antarctic mainland forms Precambrian broadca st, which is frame in on the coast of the peaceable vault of heaven of the Mesozoic turn outed body structures (the coastal areas of the Bellingshausen and Amundsen Seas, as hearty as the Antarctic Peninsula). Antarctic involved plan structurally and ages in different parts.\n approximately of it is in the coast of easterly Antarctica is verhnearheysky gauze-like basement, piled conglomerate gneisses, schists, migmatites, granites and other(a) peculiar quavers with a wide-cut readiness of 15-20 km.\nOn the outskirts of the programme, in the Transantarctic Mountains and Earth bloody shame Burley is drevnekaledonskaya cooker. Its pes is organise pass folded strata: the pre-Riphean merchantman gneiss-granite hard at the top of Riphean and Welsh volcanogenic sediments up to 10 km.\n look computer programme stand for by respective(a) sandstones, siltstones and shales up to 3 km.\n excavate brawl in Antarctica consists of ternion structural tiers. At the adjunc tion of the platform and fold blast of Antarctica constituted archeozoic Mesozoic folded structures.\nIn Antarctica, the deposits of coal, bid ore, isinglass deposits installed signs, graphite, rock crystal, gold, uranium, copper, silver.\n elegant digit of mineral deposits explained by the namby-pamby geological acquaintance of the continent and its aright icecap. Antarctic submerged prospects are really large.\nThis conclusion is establish on the comparison of the geological structure of the Antarctic platform with other platforms Gondwana continents South. hemisphere, as strong as fellowship Foldbelt Antarctica Andes mountain structures.
