Ozone layer is a region of concentration of ozone molecule. O3 (O2 +O) in the earth's atmosphere. The layer lies in the stratosphere at an altitude of 18-50 kms. The ozone layer naturally Shields earth's life from the harmful effect of the Sun's ultraviolet radiations. A severe depletion of ozone (ozone hole) in a region of the ozone layer was found particularly over Antarctica. The depletion is caused by chlorofluorocarbons and by other compounds like CCI4,CF4 etc. So, the correct answer is 'Thinning of the ozone layer'.
