Question

The depletion in Ozone layer is caused by ___________ .
A) Nitrous oxide B) Carbon dioxide C) Chlorofluorocarbons D) Methane

Answer 1

Answer:

c)Chlorofluorocarbons

Explanation:

Ozone depletion occurs when chlorofluorocarbons (CFCs) and halons—gases formerly found in aerosol spray cans and refrigerants—are released into the atmosphere (see details below). ... CFCs and halons cause chemical reactions that break down ozone molecules, reducing ozone's ultraviolet radiation-absorbing capacity.

Answer 2

Answer:

The depletion of the Ozone layer is caused by Chlorofluorocarbons.

Explanation:

Chlorofluorocarbons or CFCs are man-made chemicals that are used in refrigerators. CFCs chemical composition contains Chlorine, Fluorine, and Carbon (CFCl₃) which when exposed to UV radiation breakdowns into intermediate chlorine compounds that react with O₃ and decomposes it into O₂.
