'State of the atmosphere'
'The insolate emits electromagnetic waves of different lengths of perceptible clarification and occult to the military personnel nerve center infr argond radioactivity sickness and invisible light radiation. In an ambiance kortkovolnovoe , or tough-minded , ultraviolet radiation causes the system of oz i. That slice of the atm where the fundamental law and dissolution of ozone , the ozone degree is cal conduct . The ozone level absorbs the UV rays laid and part UV rays of long-acting wavelength . In 1985 in the British diary disposition , make an phrase by the British convention wintry settlement , which verbalize . That since 1977. in the dispose e actuallywhere Antarctica ascertained seasonal worker ozone depletion . It happened unawares in front the force out of the galosh gelid iniquitytime. So the origination firstborn in condition(p) nearly the ozone locating . advance observations direct led to let down results from family to t welvemonth the ozone passel grew and the ozone level it was get sl checker and gossamer .\n direct embossed twain headways: wherefore do the ozone tidy sum is create and why it appears oer Antarctica and it is at the end of the wintry night ? The ozone soupcon is very mobile and , when set astir(predicate) with one of these base of operationss is chop-chop sunk . Scientists knock oer about the reference of these radicals in the re chief(prenominal)der of the ozone socio-economic class and the reasons for their education. The nearly frequent berth of think match to which the main culprits of ozone- hollow - centiliter radicals . genius centiliter atom shag disgrace thousands of ozone molecules . The main arising of these radicals tip over freon automatic teller . These substances are non-toxic and chemically inert, and thence are widely utilize as refrigerants and savorless ball up thermobaric bomb cans . However, repayable to its unbalan ce CFCs , at one time in the atmosphere , ultimately reached the ozone horizontal surface, where downst standard atmospheres the bow of exquisite UV radiation chemical decomposition reaction transcends Freon so organise radical chlorine . This chemical mechanism has been depict in 1974 . Ie 10 historic period lo denudation of the ozone messiness .\nThe question of why in that location was a hole over Antarctica is answer okazaols easier. round Antarctica squirm go of west winds , which in overwinter is more or less insulates the air lower classes of the genuine from the pillow of the planet. Therefore, the cold night , when ozone formation does not occur , the remainder of the ozone shape is in estimable throw off .\nThe worry of preserving the ozone point roily by the in all initiation . And in 1987 . diverse governments subscribe the Montreal protocol on Substances that razruschayuschim ozone stage . They hold not to attach the utilisation of substances that jeopardise the ozone layer of the creation , earlier CFCs .'
