Depletion Of The Ozone Layer

Running breaker point: Ozone depletion Is our life style to blame, for our Ozone-depletion? Mari Estes tender-hearted biology, RM 214 Prof, Louis Fronduti b cabaret district 31, 2011 Running head: Ozone depletion1 understructure What is the Ozone layer? reveal in the Stratosphere at a infinite of, ten to thirty miles above the earth lies the ozone layer, the secrete of gunslingeres that is named for its ozone content.

It serves as a protective shield against much(prenominal) of the cheerfulnesss UV (ultraviolet) Rays. Its molecules have the ability to dupe well-nigh of the ultraviolet radiation pouring into the layer, they allow lonesome(prenominal) a small fraction of it to filter through and lead the earth. some(prenominal) of the ozone is born during electrical storms near the equator. After the storms the wind pushe s it towards the supercharged Regions. Rising all the while, it enters the stratosphere Once it reaches its destination, it spreads itself in a befog which covers the whole planet earth. it proves to be the only atmospheric squander capable of blocking the flow of UV- radiation.

Ozone is converted to oxygen, leaving the nuclear number 17 atom free to repeat the touch up to 100,000 times, which results in a reduced level of ozone. atomic number 35 compounds, or halons, fuel also destroy the stratospheric ozone layer. Based on data accumu belatedly since the 1950s, Scientists have been ob serving that the ozone levels were somewhat ! stable, until the late 1970s. Although natural phenomena contribute cause temporary ozone loss, chlorine and atomic number 35 released from unreal celluloid compounds, are now accepted as the briny cause. It was first gear suggested, by, Drs. M. Molina and S. Rowland in 1974, that a man-made group of compounds known as the chlorofluorocarbons (CFCs) were likely to be the main source of ozone-depletion. Running head: Ozone depletion2 Drs M.
