Cfcs Cause Deterioration of the Ozone LayerThe deterioration of the ozone grade , caused by Cfcs, endangers thelives of humans. Cfcs have a diminishing opinion on the ozone layer.Furthermore, the deterioration of the ozone cause an increase of Ultraviolet(UV) radiation which can have a negative effect on human skin and eyes. As awriter for newsweek, I have investigated the scenario and found the followinginformation.The earths air is a blanket of air that surrounds the planet.This atmospherical air is do up of many different gases, 78% nitrogen, 21%type O, and 1% of a dozen or more other gases like deoxycytidine monophosphate dioxide, helium, andozone.This atmosphere extends many miles out from the earths surface.However, this layer is not a uniform layer, from top to bottom. As one movesout from the planets surface the atmosphere becomes progressively dense. Thisatmosphere can be divide into four major regions.The first region is the troposphere which extends about 6.5 miles a bovethe planets surface. The troposphere contains the oxygen that we breath and iswhere a majority of our weather takes place.beyond the troposphere is the second region of the atmosphere, thestratosphere. The stratosphere extends from roughly 6.5-30 miles from theearths surface. The air on this region is much less dense than in thetroposphere, and its a lot drier. The stratosphere is the area that containsthe majority of the ozone layer. historical the stratosphere is the mesosphere which extends to 50 miles abovethe planet. The last region is the thermosphere. The thermospheres outermostedge is roughly 600 miles above the surface of the earth. Beyond it, theairless vacuum of space begins.Oxygen is made up of two oxygen atoms that are bonded together. In theperiodic table it is represented by O2.Like oxygen, ozone is a gas that is made up of oxygen atoms. However,a molecule of ozone is made up of three atoms of oxygen bonded together,therefore, O3, represents ozone. The ozone makes up only .01% of the atmosphere.Furthermore, 90% of the ozone is found in the stratosphere. It is concentratedin a layer between 7 and 22 miles above the earths surface.The massive depth of the ozone in the stratosphere would lead you tobelieve that it is very thick, it is not. If it were condensed, the ozonelayer would only be a a couple of(prenominal) millimeters thick (Rowland and Molina 1994. p.23).The ozone is made in the stratosphere. It is continuously being formed,broken down, and reformed, over and over again. Furthermore, the three key
