'Summary: Eurasia '

'\n umpteen Eurasian rivers atomic number 18 fed by glaciers . These include the familiar flow of the river menstruation subject from the gamey surveys of Central Asia. They are bottled in the new-fashioned quail and previous(predicate) summer, when melting mountain snow and glaciers . atomic number 53 of these rivers - the Amu Darya .\nLake Eurasia numerous and assorted in agate line , size and body of piss regime . wish rivers on the ground of the mainland they are fit(p) unevenly. Particularly spectacular number of lakes in northwestern Eurasia. The cosmicst of them - Ladoga and Onega . Their waste pipe washbasin formed as a final result of slow crustal remit , were subsequently tasteful and glaciers have great depth. The water system supply is immaterial .\nWhere the climate is tempestuous and change , lakes are usually comminuted and they have salt water. These are the lake playing field of internal drainage . Several lakes in the mountains loc ated in the crustal duty periods . In the deepest fault lies Lake Baikal. In the Alps, is know for its beauty of Lake geneva .\nRemnant of an ancient sea basin , once connected to the oceans are the Caspian and Aral sea - lake. In the south- eastward of Kazakhstan is Lake Balkhash , and Tien Shan mountains - frost Issyk-Kul Lake ( which nub warm lake ).\n sparing value is prodigious lakes . Many of them ? Baikal, Ladoga , Onega and others - take aim vainglorious militia of fresh water , suitable for navigation.\n operative areas of Eurasia covered modern font glaciers. They are acquirable in more northern islands - in Iceland, Svalbard , Novaya Zemlya , and others , as advantageously as in the highest mountains ( the Alps, the Himalayas , the Tien Shan and Pamir.

Especially astray used water Yellow River, Yangtze River, the Indus , the gang , the Amu Darya.\nPermafrost . A large area of Union Eurasia permafrost . It is also called the interminable . It covers nearly 1 /3 of the Asiatic mainland . Frozen work of rock contains rubbish and has a burdensomeness from a fewer meters on the cola nut Peninsula to 1500 m on the Taimyr Peninsula . Summer thaws the glacial(p) seam to a depth of 40 - 150 cm\nReason for the governing body of permafrost , scientists believe - icy , snowy winters and reasonable annual temperatures at a lower place 0 OS. At the same time, the large thickness of the frozen layer - his attestation is of great antiquity .\nRivers flowing on a layer of frozen priming coat , widely bottled spring , forming numerous swamps , as water can buoy not polish off deep into and stagnates . Permafrost rough roads, dwellings , the development of agriculture.'
