What is Ozone Layer

The ozone layer is the part of the Earth's atmosphere which contains relatively high concentrations of ozone gas, which is an inorganic molecule with the chemical formula O3. Ozone is a pale blue gas with a pungent (chlorine-like) smell. Though relatively high, the concentration in this layer is still small in comparison to other gases in the stratosphere.

 

The Ozone layer absorbs most of the ultraviolet radiation reaching the earth from the sun. Ozone Layer in the atmosphere is thicker over the poles than over the equator.

 

How is Ozone created?

 

When the sun's rays split oxygen molecules into single atoms, Ozone is
