Ozone is formed by the reaction of a oxygen molecule with a oxygen atom due to high UV radiation
#3O_2rightleftharpoons2O_3#
process is as
#O_2->2O#(1)due to the energy of #UV#rays
#2O_2+2Orightleftharpoons2O_3#(2)
(1)-(2)
#3O_2rightleftharpoons2O_3#
It is imprtant for the life at higher altitudes as the it absorbs the UV rays and dont allow them to fall on earth
at lower altitudes ozone is a harmful gas to the life on earth
