because O3 is fromed on reaction with O2+[O]---- O3 in presence of UV radiation
because O2 ----- [O] + [O] in presence of UV

Dear student
we know that oxygen is preset in the atmosphere
oxygen= O2
this splits into free oxygen atoms due to the high energy of UV rays
O2---- o + o
as free oxygen atom is very reactive it reacts with the oxygen molecule to form ozone
O2 + O ----- O3
Ozone layer absorbs most of the harmful UV rays coming from the sun and prevents from reaching the sun
as these rays have extremely harmful effects on human beings they cause skin cancers
Hope this helps
