Question+1

What is Ozone?

Out of each 10 million air molecules, about 2 million are normal oxygen, but only 3 are ozone.

Depletion of stratospheric ozone (O3), as commonly known as 'the hole in the ozone layer', is an issue of international concern. Most ozone is found in the stratosphere (upper part of the atmosphere), more than 10 to 16 kms from the surface of the Earth. The natural distribution of ozone around the Earth is not always happening, as seasonal winds and formation patterns contribute to lower concentrations at the equator and higher concentrations at the poles. Ozone in the stratosphere protects life on Earth as it limits penetration of ultraviolet radiation through the atmosphere, but it is considered a pollutant close to the ground.
