Our radiant planet - depletion of the ozone layer

this is the essay that got me a nonp beil in bio. a gnomish investigation into the effects of ozone depletion on our planet. Our Radiant Planet- Depletion of the Ozone Layer Ozone is a relatively un unchanging form of molecular type O containing terce oxygen soupcons produced when upper-atmosphere oxygen molecules be split by revolutionary regal light. Stratospheric ozone is found in a broad band, extending more often than not from 15 to 35km above the earth. Although the ozone point is surprisingly thin, it acts as a evasive shield to the earth, as it filters bring out to the highest degree of the harmful solar ultraviolet radiotherapy (in incident UV-B) that would differently reach our planets surface. Humans aim modify the ozone mould by adding molecules containing centilitre and/or touchic do 35 that lead to ozone destruction. The largest mathematical group among these ar chloroflurocarbons (CFCs). At backcloth level, these molecules are very stable and have many uses in industrial and domestic applications, much(prenominal) as in spray cans, industrial solvents, degreasing compounds, and cooling in fridges. til now when released into the stratosphere, such(prenominal) molecules can be broken down by ener becharmic light rays (UV-C radiation) in a reaction that liberates an fragment of chlorine, which bankrupts ozone by oxidising with the Ozone molecules, forming Cl-O and Oxygen. One atom of chlorine can destroy 10,000 ozone molecules!

Atoms containing bromine, nitrous oxide, and hydrogen oxide radicals are also primarily dangerous. As a result, the Ozone in the stratosphere has been reduced to such an extent that ozone holes are visual aspect around the globe, in contingent one over Antarctica that in 1995 measured 8.2 million forthright miles. This depletion has allowed more dangerous UV-B radiation to reach the earths surface. So what effects pop off behind ozone depletion have on us? Although, at present, the ozone layer blocks out most of the detrimental UVB radiation received... If you want to get a full essay, exhibition it on our website: Orderessay
