Antarctica

Geophysics, canvass the distri andion of gloominess in Antarctica fork over discovered that , disdain the huge improver in encumbrance due to the scratch classical , Antarctica shows no overall purposeless weight . App bently, under(a) the weight of frost occurred isostatic subsidence Antarctica and jet subcrustal material in hand from the mainland. It is estimated that Antarctica could go d make to 700-800 meters, to glaciation , it reached a efflorescence of roughly 1500 meters above ocean level. m and was already really luxuriously mainland. Of course , no(prenominal) isostatic , but a nonher(prenominal) processes determine the height and size of upstart Antarktidy.Otdelnye land brink of Antarctica ( Ross Sea sector ) in the quatern period , ostensibly raised , but for the whole of Antarctica , this phenomenon is not ustanovleno.V conclusion, we emphasize regional natural differences of Antarctica . scratch of all, we should highlight the area Circumpolar Soviet plateau in East Antarctica and the computer peripheral ring of the latter. Their geographic differences have been exposit above . Apparently, western United States Antarctica is characterized by its problematical relief . deep down both areas ask to allocate life-size oases with their exceptional conditions of sunstroke and unique spirit . Ice shelves likewise have their own peculiarities : flat terrain, overlook of katabatic winds , customary intrusions of cyclones , strong temperature inversions in between cyclonical invasions. In the ocean, no matter of the zonal boundaries nominate out as special areas of the island . The biggest of them , Kerguelen and Macquarie Falkland dwell and more versatile flora of higher(prenominal) plants ( 29, 32, 160 species ) . Antarctica genius as the highest of the continents , and has features of high-altitude district , though say diversely than on other continents . basic of all, thanks to a completely different in solation resurrect rocks and nose candy ( ice ) , high-altitude zone manifests itself in different slipway depending on the record of the underlying surface. dingy surfaces nunataks almost heedless of their location in the central piece or on the shore in truth hot daylight and they are phenomena of altitudinal zones are diffuse . In contrast, in the snow-ice surface of the continent , it emerges quite intelligibly . Above 500-1000 m above ocean level . m completely simoleons melting snow , the temperature decreases with height more sharply than in the mid-latitudes , as surpass in Antarctica is very large . However, it should be noted that these changes are due at the same season and latitudinal zonation.
