WebbThe process of ozone formation is called photolysis. Ozone is colourless just like oxygen but has very pungent odour. Ozone layer is really not a layer, it is a naturally gas in region called stratosphere, where ozone particles are scattered between 15 to 30km.

WebbOzone layer depletion is the deterioration of the upper atmosphere's ozone layer. This occurs when chlorine and bromine atoms in the atmosphere react with ozone, destroying the ozone molecules. One chlorine atom may destroy 100,000 ozone molecules, destroying faster than its formation.
