In stratosphere most of the ozone formation is assisted by :

Options

  1. Aγ -rays
  2. Bcosmic rays
  3. Cvisible radiations
  4. Dultraviolet radiation

Correct answer

D. ultraviolet radiation

Step-by-step solution

Ozone in the stratosphere is a product of UV radiations acting on dioxygen O 2 molecules. O 2 (   g ) ⟶ UV O ( g ) + O ( g ) O ( g ) + O 2 (   g ) ⇌ UV O 3 (   g )
