Ozone Depletion

Science OBAT- Global Issues (Lucy Kerslake) In Science, we have discussed numerous round issues present in modern society. One of the most kick upstairs is the issue of ozone depletion, which has been a constant threat to our halebeing and entranceway for many years now. Many strategies and plans have been put into soldiery action to stop ozone depletion and we will discuss them, as well as the impact of ozone depletion and what the issue really is. The ozone layer is a infixed filter against UV radiation from the sun. It is made of O3, and is found in the stratosphere of the Earth, 15-30km from the Earths surface. The ozone layer is formed when UV galvanizing arc hits an oxygen molecule, breaking it into single parts. The members then gather with other oxygen molecule, creating the ozone gas. The ozone gas is good at absorb the UV radiation because the ozone processes create exothermic reactions, and basically veer UV radiation into heat. This cycle is known as the ozone-oxygen cycle. The scientific compare for this process is: O2 + UV light (2O O+ O2 ( O3 Ozone depletion is caused by centiliter, which breaks trim back ozone. The release of chlorine into the atmosphere is chiefly caused by military personnel activity, and is found in many chemicals released into the atmosphere.

These include chlorofluoro one Cs (CFCs), halons, methyl group chloroform, carbon tetrachloride, hydro chlorofluorocarbons (HCFCs) and methyl bromide. These chemicals are used in refrigerators, air conditioners, leaven extinguishes, aerosols, froth and fumigants. CFCs are the most co mmon ozone depleting chemicals. They are tr! anquil of carbon, chlorine and fluorine, and have been widely used in aerosols. When ultraviolet glitter light hits them, the chlorine atom breaks moody and attacks an ozone molecule, separating it into an oxygen atom and an oxygen molecule. The chlorine atom attaches itself to the single atom until any(prenominal) other oxygen atom attacks the chlorine, making it break off and continue the process thousands of times.
