Who enhances the degradation of ozone?
(d) Water vapors
This question was addressed to me during an interview.
My question is based upon Environmental Issues in chapter Environmental Issues of Biology – Class 12
The correct option is (b) Chlorofluorocarbons
The explanation: Chlorofluorocarbons (CFCs) enhances the degradation of ozone by disturbing the cycle of ozone formation. CFCs upon entering in stratosphere react with UV and release chlorine ions. These ions act as catalysts and degrade ozone releasing molecular oxygen.
