Question

Ozone absorbs low energy ultraviolet radiation and decomposes back to oxygen.

• A. True
• B. False

Answer 1

The correct option is A

True

Yes, ozone absorbs low energy ultraviolet (UV) radiation and decomposes back to oxygen.


In fact, even the reverse process of converting oxygen to ozone also occurs because of UV radiation of slightly higher energy. As a result of this cyclic process, the level of ozone remains constant in the atmosphere.
