How is the ozone layer destroyed in the atmosphere?
– The main cause of the destruction of ozone layer are the atoms of chlorine and bromine. When the gases containing these atoms are released from any process on the surface of the earth, they get accumulated in the lower layers of the atmosphere since they are non-reactive. These gases have very long life, sometimes even extending to more than hundred years. The gases containing chlorine and bromine slowly rise in the upper layers of the atmosphere. When they reach the stratosphere, the chlorine and bromine atoms get separated from the gas. They react with ultraviolet rays protecting ozone layer and convert it into O2, oxygen, which cannot protect the ultraviolet rays coming to the surface of the earth.
