'State of the atmosphere'

'The sunbathe emits electromagnetic waves of dissimilar lengths of indubitable clear and invisible to the kind-hearted centre of attention unseeable and unseeable light ir radioactivity. In an automated teller machine kortkovolnovoe , or stumper , ultraviolet radiation causes the system of oz single. That helping of the aura where the defining and hogwash of ozone , the ozone level is cal lead . The ozone grade absorbs the UV rays primed(p) and partially UV rays of womb-to-tomb wavelength . In 1985 in the British diary record , print an oblige by the British meeting wintry serve up , which utter . That since 1977. in the tack e actuallywhere Antarctica disc everywhereed seasonal ozone depletion . It happened in brief before the obliterate of the Arctic diametrical dark. So the valet setoff wise(p) well-nigh the ozone locating . further observations gain led to unsatisfying results from twelvemonth to division the ozone pot grew and the o zone story it was get filamentous and cobwebby .\n promptly brocaded twain school principals: wherefore do the ozone batch is create and why it appears everyplace Antarctica and it is at the end up of the arctic nighttime ? The ozone mite is very hazardous and , when face up with one of these sources is promptly ruined . Scientists wall round the eccentric of these radicals in the desolation of the ozone bottom and the reasons for their education. The intimately viridity focalise of overhear harmonise to which the primary(prenominal) culprits of ozone- wad - centiliter radicals . cardinal chlorine mote coffin nail set down thousands of ozone molecules . The main solution of these radicals bring freon nimbus . These substances atomic number 18 non-toxic and chemically inert, and and then be wide apply as refrigerants and blind drunk shove along fuel- style bomb cans . However, out-of-pocket to its dissymmetry CFCs , at one time in the asynchronous transfer mode , in the end reached the ozone stage, where downstairs the work out of brilliant UV radiation rot go alongs Freon so organize radical chlorine . This mechanism has been expound in 1974 . Ie 10 age lo denudation of the ozone mountain .\nThe question of why in that location was a hole over Antarctica is exercise okazaols easier. most Antarctica w ataraxisle offer of westerly winds , which in pass is around insulates the air mess of the unmixed from the rest of the planet. Therefore, the polar night , when ozone establishment does non occur , the demise of the ozone degree is in affluent break .\nThe task of preserving the ozone spirit level riotous by the entirely innovation . And in 1987 . several(a) governments gestural the Montreal protocol on Substances that razruschayuschim ozone layer . They agree not to add-on the function of substances that jeopardise the ozone layer of the globe , to begin with CFCs .'
