Question

Select the list of greenhouse gases mentioned in descending order of their abundance.

• A. Oxygen, Carbon dioxide, Methane, Nitrous oxide, CFCs
• B. Carbon dioxide, CFCs, Methane, Nitrous oxide
• C. Carbon dioxide, Methane, Nitrous oxide, CFCs
• D. Nitrous oxide, Methane, Carbon monoxide, CFCs

Answer 1

The correct option is C

Carbon dioxide, Methane, Nitrous oxide, CFCs

The most abundant greenhouse gas in the atmosphere is carbon dioxide, followed by methane, nitrous oxide and then CFCs. Oxygen is not a greenhouse gas. Carbon monoxide is a very weak greenhouse gas, but has quite a few indirect effects on global warming.
