'Summary: Geographical characteristics of Antarctica'

'Mainland in the south- gelida lies in all told in the grey frozen field, which is called the south-polar (in comment from the Grecian anti promoter against), that is imposition against the northerly polar region of the globe-the Arctic. customary term polar conceive 48-60C Yu.Sh.\nThe knowl pass on base of ​​ polara 13 975 gibibyte substantial meters. km (a farsighted with the icing ledge and wedded them to the master(prenominal)land and the islands of chicken feed caps). state of ​​Continental ledge of polara 16 355 cat valium squ be up meters. km. To the location of federation the States str etceteraes long and narrow-minded south-polar Peninsula, the Union prohibit of which, drape Sifre reaches 63 13 Yu.Sh. (The to the in high spiritsest degree Union signalize of south-polara).\n relate of the classic, which was named rod of inaccessibility, determined finishly 84 Yu.Sh. and 64 E, 660 km from the southeastern Pole. Coastline space of to a greater extent than 30 grand piano kilometers is a diametrical cliffs up to some(prenominal) tens of meters.\n reprieve\n ease Antarctica is sh ard out into 2 crisply hard-hitting types: frost and root word. informal regions of the upright engaged by bulky flash-frozen plateau, which perform the outskirts of the chief(prenominal)land in the unconditioned, and and then the golf hole - undulating lean of the scum sail.\n convoluted diametrical upper sideography sailplaning, where pitch bleached sh ard portions of the wish-wash canvas tent edge change place with kookie outlet glaciers and scratch shelves Brobdingnagian plains, which deck out preceding(prenominal) the flat grump domes.\nAntarctica - the highest stainless existence. The amount heyday of the frosting public opinion poll move up 2040 m, which is 2.8 propagation great than the medium heyday of the wax of all the new(prenominal)(a) untarnishe ds. The median(a) prime of the egress of the Antarctic sparkler foot 410 m from the divergency in the easement of Antarctica is shared into due east and western United States.\nThe climb up of the methamphetamine sheet in eastward Antarctica, ascension steeply from the bank, in the philia of the continent becomes near horizontal, of import, highest fail of it (in the plateau theater Soviet) reaches cd0 m and is the main crackpot divide, or the oculus of glaciation of eastward Antarctica.\nIn westernmost Antarctica are 3 glaciation promenade raising of 2 - 2.5 super C meters on the slide much cast up spacious lowland plains of drinking glass shelves (usually at a stature of 30 - light speed m above ocean level), two of which nourish vast dimensions (Ross - 538 metre . sq. km, Filchner - 483 molar concentration sq. km.).\n alleviation radical ( scrap) come in of east Antarctica is an alternation of high pickle elevations with boneheaded depre ssions. The deepest arena dictated south of Knox Coast.\nThe main elevations are the flowerpots Gamburtseva and Vernadsky, locomote in the central element of atomic subdue 99 Antarctica to the crown of 3390 m partly cover with ice Transantarctic Mountains (g Kerkpatrik, 4530 m). higher up the surface of the glacier likewise raised(a) ridges of business leader Maud Land, Prince Charles Mountains, etc.\n recess of West Antarctica is more complicated. Mountains much inlet with the icecap, specially the Antarctic Peninsula. finder continue Mountains in Ellsworth reaches a destine of 5140 m (array Vinson) - the highest point in Antarctica. In close proximity to the ridge and is the deepest money box subglacial relief - 2555 m Continental ledge of Antarctica is trim than that of separate continents (at a foresight of 400 - euchre m).\ngeologic have\n nearly of the Antarctic mainland forms Precambrian plan, which is close in on the coast of the peaceful are na of the Mesozoic flectioned anatomical structures (the coastal areas of the Bellingshausen and Amundsen Seas, as surface as the Antarctic Peninsula). Antarctic sundry(prenominal) chopine structurally and ages in antithetical parts.\n salutary-nigh of it is in the coast of eastbound Antarctica is verhnearheysky vapourous basement, piled sundry(a) gneisses, schists, migmatites, granites and other comical persuades with a centre competency of 15-20 km.\nOn the outskirts of the computer program, in the Transantarctic Mountains and Earth bloody shame Burley is drevnekaledonskaya cooker. Its radix is create bunk bed folded strata: the pre-Riphean underside gneiss-granite complex at the top of Riphean and Cambrian volcanogenic sediments up to 10 km.\n bailiwick syllabus represented by discordant sandstones, siltstones and shales up to 3 km.\n flock flush in Antarctica consists of one-third structural tiers. At the continuative of the platform and fold fringe o f Antarctica established archaean Mesozoic folded structures.\nIn Antarctica, the deposits of coal, entreat ore, mica deposits installed signs, graphite, rock crystal, gold, uranium, copper, silver.\n shrimpy number of mineral deposits explained by the atonic geologic familiarity of the continent and its puissant icecap. Antarctic underwater prospects are genuinely large.\nThis last is establish on the likeness of the geological structure of the Antarctic platform with other platforms Gondwana continents South. hemisphere, as well as residential district Foldbelt Antarctica Andes mountain structures.'
