What is ozone?

It’s a layer that protects the earth  from the ultraviolet radiation of the sun. At lower levels, ozone becomes a major pollutant.

From the fig we can observe that the harmful radiations coming to earth is absorbed by the ozone layer & due to the CFC ‘s coming from the earth surface will cause the destruction of that layer. Thus the U.V rays enter to the earth.
