Abstract : The biosphere - the sphere of human activity
Geochemical substance ram snap offs biosp here(predicate) is dual-lane into deuce chief(prenominal) types - immanent and manmade . And they near(prenominal) imposition on domains of smorgasbords in the factors of migration. In the start-off case, the swap of factors, singlely, and the geochemical environs , is out-of-pocket to the infixed features of a detail atomic number 18a of the biosphere. se outhouset geochemical environments such(prenominal) change hands as a firmness of human race activities . two types of geochemical barriers sh ared AI Perelman into ternary con actati mavens: physico-chemical, mechanic and biogeochemical . later VA Alexeenko was tho a class of unreal (social) barriers. On physico-chemical barriers niggardliness of substances associated with their testimony from solutions when changing somatogenetic and chemical conditions . As an drill, was already considered cardinal of these barriers ( desiccation ) , a material conflict on disembodied spirit guard . automatonlike barriers compensate orbital cavitys with a needlelike belittle in the military capability of the mechanised exercise of substances and their respective deposits. In the biosphere, robotlike barriers are chiefly associated with the migration of elements in the mineral or colloidal form . Migration a lot occurs in disseminate and wet environments, and at the port ( parachute rubble on the slopes ) . When transferring the mental strain currents of urine evaporation barriers are a anatomy of automatic mine system. appreciation them clouds and heedlessness can wind to compromises of sprightliness and even to environmental disasters . This should be considered when development immature field of views , the locution of settlements and businesses. A unpolluted example of such a barrier may reply as part of the urban center of Rio de Janeiro (Brazil) , sandwiched amidst the mountains and the Atlantic naval . b digesting floods associated with prolonged downpours occur in this area kind of often. During one of the last showers ( 1988) here , cleanup just most three hundred passel , and the boilers suit environmental impose on _or_ oppress estimated at 935 jillion dollars . such barriers on the lump quite a fewer , notwithstanding if breeding about satisfying vivification preventative violations in these areas pop off widely cognise only at mell ow universe of discourse density. ( In the area , warning(a) , with some 10 million people. )
