Question:
Formation of ozone in the upper atmosphere from oxygen takes place by the action of:
Formation of ozone in the upper atmosphere from oxygen takes place by the action of:
Show Hint
Ultraviolet rays play a crucial role in the formation of ozone in the upper atmosphere.
Updated On: Mar 25, 2026
- Nitrogen oxides
- Ultraviolet rays
- Cosmic rays
- Free radicals
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Ozone formation.
Ozone is formed in the upper atmosphere from oxygen molecules under the influence of ultraviolet (UV) light. UV light breaks apart the oxygen molecules, leading to the formation of ozone.
Thus, the correct answer is (2).
