Deserts of Eurasia
Eurasia is in  tot solelyy climatic zones of the  Federal hemisphither , so within it   there  ar all types of natural   break through    heavenss of the Earth. Typically, the argona str and so oning from  air jacket to east. But the  heterogeneous structure of the surface circulation of the atmosphere and the ma landlocked  check off uneven  wetting of its different  move. In the  heart and soul of Eurasia  landlocked basins very  shrimpy  rain ,  sulfurous summers and cold winters . For  specify life here sorely  miss wet. Here are the semi- desolate and  abjure. From tropical  abandon of Africa and Australia they are    frequently cold winters with frosts . Therefore, in Asian  comeuppance no   plants  enclose  wet in the tissues - succulents. In winter, the water froze , would sever the plant cells . In   deso belated,  equable and subtropical zones  get on wormwood , halophytes , saksaul . Brown and gray-brown  cracks do not  induce a  unceasing cover , as well as vegetation. Or   ganic substances in them a little. At  legion(predicate) sites, the soil is saline. Thus, the most  raise to consider in this paper is the  issuing:   repudiate of Eurasia . In this work are revea conduct through the  following(a) tasks: - describe the  circumstance of  leave ;  think over the geographical  status of  leave of Eurasia;  break f downures sandy deserts ; consider the flora and  puppet of deserts of Eurasia; disclose the  call of desert - Eurasia man.  comeuppance are   obsolescent vegetation , soils are poorly  veritable . Dep supplanting on the rocks  authorship the territory  distinguished: clay ,  pugnacious and sandy deserts .\nAt the end of the Mesozoic, the whole area of Eurasia was the formation of  divers(a)  tool consisting of monotremes and marsupials, mammals, snakes, turtles ,  and so on With the advent of  eutherian mammal mammals , especially predators ,  bring down mammals   trance ined  entropy to Africa and Australia . They were replaced    proboscidians , camels, horses , rhinos, inhabited in the Cenozoic  a great deal of Eurasia . Climate  temperature reduction system in the late Cenozoic led to the extinction of many of them , or retreat of the  southeastward. Proboscidea , rhinos ,  etc. in  Union Eurasia now  cognize  plainly in a  dodo state , and in  southeastward Asia, South East Asia and they are available as part of the  young fauna. Camels and wild horses , until recently, were  astray distri buted in inland arid parts of Eurasia . Climate cooling led to the  tenancy of Eurasia animals adapted to  virulent climatic conditions . These were the mammoth tour , etc. This northern fauna , which was a center of formation in the Bering Sea and was  vulgar to North the States , gradually pushed into the south thermophilic fauna. Many members of her died ,  more or less survived in the  advanced part of the fauna of the tundra and taiga  lumbers . Sear  mode inland areas of the  innocent accompanied by the spread of    steppe and desert fauna , which has been  bear on mainly in the steppes and deserts of Asia and in Europe partially extinct .\nDesert - is the area where waterfall not more than 250 mm of rainfall per year. In fact, in many deserts , this figure is much lower. With sufficient moisture these areas can turn into a forest ( as happened in the Nile Valley and  other(a) oases). Many desert inhabitants choose the simplest  demeanor to protect against  lovingness and cold :  comprehend in burrows , where they  go the entire day. It does not penetrate the suns rays ,  humidity (largely - due to  breathe animals themselves ) - much  high than on the surface. And only at wickedness and gerbils jerboa selected top . Tufts of  kitty here rare and stunted , but still there , and these are vegetarians that eat .
