How is ozone formed in the stratosphere?

Options

  1. AOzone is a natural byproduct of photosynthesis.
  2. BOzone is formed by the combustion of fossil fuels.
  3. COzone is produced when UV radiation splits molecular oxygen.
  4. DOzone is a byproduct of volcanic eruptions.

Correct answer

C. Ozone is produced when UV radiation splits molecular oxygen.

Step-by-step solution

Ozone in the stratosphere is formed when UV radiation breaks apart molecular oxygen (O 2 ) molecules, creating free oxygen (O) atoms that combine with molecular oxygen to form ozone (O 3 ).
