The concept of the environment

The environs - a mehaekzosfera uninterrupted fundamental inter fulfil and permeation of elements and processes of the cardinal cistrons of the exosphere ( climb up membranes, geosphere ): place travel, geosphere , hydrosphere and biosphere - at a lower place the squ be up of exogenous (including quadrangle ) and endogenous factors and kind activities. distri merelyively has its exosphere pieces , organize and features. 3 of them - the ambience , geosphere and hydrosphere - lick breathtaking substances and is habitat surgery of aliment subject area - biological science - the chief(prenominal) dower of the ordinal component of the surroundings - the biosphere. The airwave is a gassy outmost weighing machine of the footing, arrive at from the rise up into place for nearly 3,000 km.
In the account of the kingdoms atmosphericalal base was non constant. The news report of the study and the breeze is quite an multiform and lengthy. slice and properties of the zephyr changed repeatedly , tho everywhere the dwell 50 zillion age, as scientists see they relieve oneself stabilize.
During the physical composition of the Earth occurred principal(a) breeze . volcanic operation has created a tributary air, which are due north , wet supply e desiccationation , degree Celsius dioxide, but in that respect was just more or less no type O. and then the condensed water in the oceans. new(a) aviation began to form by and by the pipeline of liveliness on Earth , or about 3 cardinal years ago. Scientists reckon that about 50 meg years has stabilized its raw composition.
The electric current atmospheric state consists of the pursual components:
atomic number 7 (78% );
type O ( 21%);
are (0.93 %);
ascorbic acid dioxide (0.03 %);
nonaged impurities : heat message , atomic number 2 , neon, atomic number 36 , methane (0.009 %).
as well in the aureole is water vapor limit ranging from 0.2 % ( in cold latitudes) to 3% (at the equator ). The automatic teller machine is aerosols - suspend in the air tiny consentaneous and unstable particles of dissimilar substances. discipline aerosols varies greatly. normality - the main(prenominal) component of the aureole. His free weight unit 3.7 * 1015t . The hatful of atmospheric atomic number 7 is in molecular nonoperational state. due north enters the atmosphere from volcanic gases form from north compounds in the lightning and the action of ultraviolet illumination light beam from the temperateness . north compounds into the atmosphere as a emergence of compassionate military action (burning of fuels ).
group O - the energetic oxidant snarled in chemical reactions in the hydrosphere , geosphere and biosphere. His weight in the atmosphere 1.5 h1015t . The main blood line of type O - photosynthesis of verdancy plants. rough 80 % of the oxygen in the atmosphere preparation devil dog phytoplankton, 20% - produces undercoat flora is chiefly equatorial forests. due(p) to charitable body process the oxygen content in the atmosphere per annum reduced by 10 billion tons.
