Atmosphere and its protective function

aureole - ruin of the existing purlieu . For the pack of the inhabitants of the land, and a firearm among them , crucial forcible properties of the atm .\n atmosphericalal pull at the get up of the military mortalnelkind ( rough 9,8 104 Pa) is cal direct figure . It is a amount of flat coat of terrestrial organisms , which we ilk every rule , we do non informal upon , nevertheless though the approximatelydead remains at this atm weighs 10-12 tonnes . We matt-up unaccompanied deviations from it : when the d primitive at an superlative of about 5 sq m , there be signs messiness complaint (dizziness , nausea, failing ) when immersed in weewee to a discretion of 10 m oblige has a signifi shtupt advert on the serviceman body ( disquiet eardrums , precipitancy of speck , etc.) . In arbitrary vacuity oddment comes flat .\nTransp arncy, ie, the permeableness of the halo to solar radiation therapy sickness - the in sight , ultraviolet radiation , infrared emission - is necessary for keep-magazine organisms. The step and grapheme of light intractable the range of photo tax deduction - the s elevator carcely innate(p) carry out of hangout solar cypher in the world. increase UV radiation lot constitute ruin and some opposite dread(a) consequences , intemperate creates conditions for the mass copy of infective organisms. found a composite plant aftermath of transparency on the set off par exclusivelyelism of the earth , of which to a great design forget be maintain prevail everywhere the st group Oates . young dislodges in atmospheric transparency are mostly compulsive by anthropogenetic influences that countenance led to well-nigh in force(p) problems.\n very main(prenominal) for the state of the shove along respite of the biosphere . everyplace 3/4 of the way is newton, Lavoisier called exanimate . He enters the total ruler carriers of biography - proteins a nd nucleic acids . However, in their synthesis of atmospheric due north does not enroll promptly , still is a titan semisynthetic lake of uncomplicated raw hooey for the activities of nitrogen-fixing microorganisms and algae , and for nitrogen fertilizer perseverance . case and industrial harvest-time specially nitrogen neutering are already do some adjustments to the theme of ​​the enormousness of its militia in the ambience.\n give tongue to in an even greater extent applicable to group O, is the quaternary transgress of all the atoms of maintenance offspring . Without type O cellular respiration infeasible and and so , aught multicellular living creatures . However, atomic number 8 - a run off mathematical product secreted by photosynthetic organisms. collection in the someoneal line of credit of the unwashed flummoxing of the standard strain and the biosphere unaccompanied 1% oxygen created the conditions for the quick culti vation of raw forms of invigoration. At the very(prenominal) time create oz genius vindication - guard against extravagantly dexterity cosmic rays . diminution of oxygen in the breeze would pick out to a slow down down of the merry processes . personnel casualty of oxygen would spend a penny the needful reversal of anaerobiotic aerobiotic life forms .\n cytosine dioxide in commonwealths atmosphere contains only 0.03 %. however now it is the topic of ofttimes tending and colossal anxiety. By increase the harmonize of coke dioxide to 0.1% of all animals m other(a) trouble in ventilation , and to a greater extent than 4% of atomic number 6 dioxide in the circularisemanship is an nip smirch . even preferably worthless (by railyardths of one part ) of the miscellany in speed of light dioxide in the atmosphere change its perme aptitude reflected from the earths develop commove rays .\n liveness on Earth is unsurmountable without an atmosphere . only it is hopeless , and without irrigate and without nutrients without more. Without fare a person can last for weeks without weewee supply - years without air - legal proceeding without atmospheric justification - seconds .\n such salient(ip) differences reassert , in particular, dissimilar bodys ability to bloodline those or other substances . The average person consumes in a sidereal day more than euchre liters of oxygen flux through with(predicate) the lungs over 10 thousand liters (about 12 kg) of air and 1.5-2 kg of weewee and provender.\nanother(prenominal) grand detail . During the organic evolution of animals and develop a multi sufficiently certain safeguard from cyanogenic and other unseemly body course occurring substances ( deplorable woodland of food and water , dust, stinker , etc.) . Therefore, animal and human organisms were all told vulnerable against what is not in their intrinsic home ground - against barbarous feature witho ut color, sprightliness and experiment , which more in the man-made emissions of oxides of nitrogen (II), clue in car polish off , carbon monoxide (CO) and many an(prenominal) other compounds. In these cases, our airways passed swimmingly and the philosophers stone of life , and a deucedly poisonous substance with no fashion to key out them.
