Question

Match the global warming activities given under column I with respective greenhouse gases produced under column II.

• A. A= r, B=s, C=t, D=p
• B. A= q, B=s, C=t, D=r
• C. A=s, B=r, C=q,D=p
• D. A=p, B=s, C=t, D=r

Answer 1

The correct option is D

A=p, B=s, C=t, D=r

Carbon dioxide, nitrous oxide, methane, and CFCs are all greenhouse gases. Combustion of fossil fuels gives rise to carbon dioxide. Swamps and rice fields are a major source of methane. Methane is released from anaerobic respiration in the wetland soils. Refrigerators contain CFCs which lead to the ozone depletion in the atmosphere. The burning of biomass leads to the release of nitrous oxide.
