Which synthetic chemical compound is primarily responsible for the depletion of the ozone layer in the stratosphere?
Answer
A. Chlorofluorocarbons (CFCs)
The correct answer is A. Chlorofluorocarbons (CFCs) — Step 2: Chlorofluorocarbons (CFCs), used in refrigerators and fire extinguishers, release chlorine atoms under ultraviolet radiation which destroy ozone () molecules.
Step-by-step solution
- Step 1: Identify the primary agent responsible for ozone degradation in the upper atmosphere.
- Step 2: Chlorofluorocarbons (CFCs), used in refrigerators and fire extinguishers, release chlorine atoms under ultraviolet radiation which destroy ozone () molecules.
Common mistake: Selecting greenhouse gases like carbon dioxide or methane instead of chlorofluorocarbons.
Concept tested: Depletion of the ozone layer
