How is ozone formed in the upper atmosphere? Why is damage to ozone layer a cause of concern to us? What causes this damage?
Ozone is the chained molecule, harmful reactive gas and composed of three oxygen atoms that protect the earth from harmful radiations coming from outer space.
In the stratosphere, ozone is produced naturally when high energy solar radiation falls on the molecule of oxygen, O2, and results in the splitting of diatomic oxygen under the process of photolysis.
When the free oxygen radical collides with another O2 atom, it combines and forms ozone O3.
Ozone is formed through the following chemical reaction:
O2 ----> O + O (radicals)
An oxygen radical merge with diatomic oxygen to form an ozone molecule.
O2 + O -----> O3
The ozone layer protects us from the harmful effects of short wavelength and hazardous ultraviolet radiation coming from the sun. Under the clear sky, there is an inverse relationship between the ozone layer and solar ultraviolet radiation measured on the Earth's surface. Lower ozone level can lead to higher solar ultraviolet radiation.
The fullform of CFC is ChloroFluoro Carbon.
Depletion of the ozone layer leads to hazardous environmental effects by increasing exposure to dangerous ultraviolet rays and can cause cataract, skin cancer and weakened immune system.
