Question

what happens when the higher energy uv radiation act on the oxygen at the higher level of the atmosphere answer me hurry

Answer 1

The high energy ultraviolet radiation (UV radiation) coming from the Sun splits oxygen
gas into free oxygen atoms

O2 in the presence of uv rays -> O(oxygen ) + O (oxygen)

The free oxygen atoms thus produced react with an oxygen molecule to form ozone molecule

O2 + O -> O3(ozone )

Answer 2

Ozone is formed at the higher level of atmosphere by the action of UV radiation on molecule. High energy UV radiations split apart some oxygen molecules into atomic oxygen which react with molecular oxygen to form ozone molecules.
