Question

multiple choice question. the human - induced destruction of ozone occurs when chlorofluorocarbons (cfcs) break down in the atmosphere as they are struck by ultraviolet radiation. the released ______ leads to the breakdown of ozone. options: hydrogen, fluorine, carbon, chlorine

Explanation:

Chlorofluorocarbons (CFCs) break down in the atmosphere when struck by ultraviolet radiation, releasing chlorine atoms. These chlorine atoms react with ozone molecules, leading to ozone destruction. Carbon, fluorine, and hydrogen in CFCs do not directly cause ozone - layer depletion in the same catalytic way as chlorine.

Answer:
