How is ozone layer formed? State its importance to all life forms on earth? Why the amount of ozone in the atmosphere dropped sharply in the 1980s?
Answers (1)
The ozone layer is formed when the sunlight breaks apart an oxygen molecule into two oxygen atoms and these oxygen atoms collide with another oxygen atom which makes ozone.
The ozone layer protects the Earth from harmful ultraviolet rays (UV rays) which comes from the Sun. Without the Ozone layer in the atmosphere, life on Earth would be very difficult as human will start to severe diseases like skin cancer and other genetic disorders. Even plants cannot live and grow in heavy ultraviolet radiation, nor can the planktons that serve as food for most of the ocean life.
As we know that ozone depletion occurs when chlorofluorocarbons (CFCs) and those gases which are found in aerosol spray cans and refrigerants, etc, are released into the atmosphere. CFCs and halons cause chemical reactions that break down ozone molecules and leads to reduce ozone's ultraviolet radiation-absorbing capacity.
