Formation of ozone
The UV radiation having higher energy divides molecular oxygen (O2) into two free oxygen (O) atoms.These free oxygen atoms combine with molecular oxygen atoms to form ozone(O3).
Ozone awareness day
To create awareness among people about the importance of the ozone layer,World Ozone Day is celebrated on September 16 every year.On this day, several seminars, webinars, and talks are conducted by various organizations to create awareness.
Ozone layer depletion
Chlorofluorocarbons (CFCs), carbon tetrachlorides, etc. are the substances responsible for causing ozone layer depletion. In 1987, the Montreal protocol was formulated to reduce the use of ozone layer-destroying substances.In Antarctica,the first ozone hole was identified.
Ways to protect the ozone layer
Use environment friendly products
Minimize the emission of greenhouse gasses from vehicles.
Avoid use of chlorofluorocarbons
