Our radiant planet - depletion of the ozone layer

this is the essay that got me a one in bio. a microscopic investigation into the do of ozone depletion on our planet. Our Radiant Planet- Depletion of the Ozone Layer Ozone is a comparatively unstable form of molecular type O containing three oxygen soupcons produced when upper-atmosphere oxygen molecules be split by ultra regal light. Stratospheric ozone is found in a gigantic band, extending generally from 15 to 35km above the earth. Although the ozone form is surprisingly thin, it acts as a evasive shield to the earth, as it filters bring come on most of the harmful solar ultraviolet radiation (in mishap UV-B) that would otherwise reach our planets surface. Humans aim damaged the ozone layer by adding molecules containing centilitre and/or atomic number 35 that lead to ozone destruction. The largest group among these ar chloroflurocarbons (CFCs). At ground level, these molecules ar very stable and have many uses in industrial and domestic applications, mu ch(prenominal) as in spray cans, industrial solvents, degreasing compounds, and chill in fridges. However when released into the stratosphere, such(prenominal) molecules can be mixed-up down by energetic light rays (UV-C radiation) in a reaction that liberates an atom of chlorine, which destroys 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 likewise primarily dangerous. As a result, the Ozone in the stratosphere has been reduced to such an extent that ozone holes are appea ring around the globe, in extra one over An! tarctica that in 1995 measured 8.2 million resolute miles. This depletion has allowed more dangerous UV-B radiation to reach the earths surface. So what effects leave behind ozone depletion have on us? Although, at present, the ozone layer blocks out most of the damaging UVB radiation received... If you indigence to get a full essay, order it on our website: OrderCustomPaper.com
