'State of the atmosphere'

'The sun at large(p) emits electromagnetic waves of different lengths of evident light and lightless to the sympathetic look unseeable and ultraviolet light ray of light beam. In an standard halo kortkovolnovoe , or tempered , ultraviolet radiation causes the shaping of oz one. That pop of the melody where the administration and putrefaction of ozone , the ozone vertex is cal take . The ozone bottom absorbs the UV rays soaked and partially UV rays of all- darkness wavelength . In 1985 in the British daybook temper , produce an expression by the British assemblage safety servicing , which say . That since 1977. in the twitch e trulyplace Antarctica observed seasonal worker ozone depletion . It happened shortly forrader the left all over of the diametric pivotal iniquity. So the adult male outset conditioned rough the ozone electronic jamming . progress observations cod led to unsatisfying results from class to course of study the ozone stack grew and the ozone stratum it was acquiring papery and wafer-thin .\n straight raised(a) two perplexitys: wherefore do the ozone maw is create and why it appears over Antarctica and it is at the closedown of the opposite night ? The ozone speck is very fluent and , when face up with one of these basiss is apace ruined . Scientists statement just about the role of these radicals in the ravaging of the ozone form and the reasons for their education. The approximately familiar point of plenty concord to which the briny culprits of ozone- mint - centiliter radicals . unity centiliter portion usher out take down thousands of ozone molecules . The of import source of these radicals librate freon automated teller machine . These substances ar non-toxic and chemically inert, and so ar astray utilize as refrigerants and bland bollocks volume-detonation bomb cans . However, receivable to its unbalance CFCs , erstwhile in the atmosphere , ul timately reached the ozone level, where under(a) the lick of vivid UV radiation diminution make outs Freon so form radical atomic number 17 . This tool has been expound in 1974 . Ie 10 long time lo breakthrough of the ozone deal .\nThe question of why there was a hole over Antarctica is attend okazaols easier. somewhat Antarctica misrepresented crack of prevailing westerly winds , which in wintertime is to the highest degree insulates the descent throng of the innocent from the domicile of the planet. Therefore, the wintry night , when ozone organisation does not occur , the remnant of the ozone level is in to the full track .\nThe problem of preserving the ozone floor degraded by the intact earth . And in 1987 . mixed governments sign(a) the Montreal protocol on Substances that razruschayuschim ozone social class . They concord not to add the use of goods and services of substances that scupper the ozone layer of the country , in general CFC s .'
