Depletion Of The Ozone Layer

Running breaker point: Ozone depletion Is our life style to blame, for our Ozone-depletion? Mari Estes humane biology, RM 214 Prof, Louis Fronduti b cabaret district 31, 2011 Running head: Ozone depletion1 induction What is the Ozone layer? reveal in the Stratosphere at a quad 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 frequently of the cheerfulnesss UV (ultraviolet) Rays. Its molecules have the ability to take on well-nigh of the ultraviolet radiation pouring into the layer, they allow totally a small fraction of it to filter through and gather the earth. some(prenominal) of the ozone is born during electrical storms near the equator. After the storms the wind pushes it towards the aerat ed Regions. Rising all the while, it enters the stratosphere Once it reaches its destination, it spreads itself in a hide out which covers the whole planet earth. it proves to be the only atmospheric be adrift capable of blocking the flow of UV- radiation.

Ozone is converted to oxygen, leaving the atomic number 17 atom free to repeat the act upon up to 100,000 times, which results in a reduced level of ozone. bromine compounds, or halons, fuel also destroy the stratospheric ozone layer. Based on data accumu novel since the 1950s, Scientists have been observing that the ozone levels were s omewhat stable, until the late 1970s. Al! though natural phenomena contribute cause temporary ozone loss, chlorine and bromine released from synthetic celluloid compounds, are now accepted as the primary(prenominal) 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.
