Ozone layer is a protective layer in the stratosphere. It protects the earth's inhabitants from the harmful UV rays of the sun which if not blocked may cause skin cancer. The ultraviolet rays split the oxygen molecule into free oxygen atoms, these free oxygen atoms combine with the oxygen molecule to form ozone. This salient layer lies at distance of 12-15 miles beyond the earth surface.
