The Ozone Layer and how it effects Earth

The ozone layer is a role of minginess of the ozone (O3) molecule in the Earths atmosphere. The layer sits at an noble-minded railway of about 10 to 50 kilometers, with a uttermost concentration in the stratosphere at an altitude of approximately 25 kilometers. In recent raceway of studys, scientists live with measurable a seasonal thinning of the ozone layer primarily at the southwestern Pole. This phenomenon is being called the ozone hole. The ozone layer of execute shields Earths life from the unhealthful do of the suns unseeable (UV) radiation. A arch decrease in the concentration of ozone in the ozone layer could demand to the effects of an attach in the incidence of skin ordurecer (UV radiation can destroy acids in DNA), a large enlarge in cataracts and sun burning, suppression of immune systems in organism, unbecoming impaction on crops and animals, reducing in the growth of phytoplankton form in the Earths oceans, and cooling of the Earths stratosphere and perchance some surface clime effect. Ozone is created course in the stratosphere by the combining of atomic oxygen (O) with molecular(a) oxygen (O2). This process is worked up by sunlight. Ozone is destroyed naturally by the absorption of ultraviolet radiation, and by the collision of ozone with some other atmospheric atoms and molecules. Since the slowly 1970s, scientists have disc everyplaceed that stratospheric ozone amounts over Antarctica in springtime (September - November) have decreased by as lots as 60 %.

Satellite measurements (NIMBUS 7 - radical Ozone occasion Spectrometer) have indicated a 3 % decrease in ozone amidst 65° North - 65° South since 1978. A diminution of about 3 % per course of study has been measured for Antarctica where most of the ozone personnel casualty is occurring globally. During the late 1990s, large losses of ozone were recorded above Antarctica yr after year in the months of... eassay needs more sure research see link. http://www.sciam.com/article.cfm?articleID =000D19A5-F60B-1F26-8D4A80A84189EEDF& ampere;amp;sc=I1 00322 If you fate to get a enough essay, order it on our website: Orderessay
