Question

How is ozone layer formed ??

Answer 1

Stratospheric ozone is formednaturally by chemical reactions involving solar ultraviolet radiation (sunlight) and oxygen molecules, which make up 21% of the atmosphere. In the first step, solar ultraviolet radiation breaks apart one oxygen molecule (O2) to produce two oxygen atoms (2 O) (see Figure Q2-1).

Answer 2

high in the atmosphere,some oxygen is absorbed energy from the sun's ultraviolet rays and split to form single oxygen atom.these atom combined with molecular oxygen to form ozone molecules.
