Question

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

• 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

CO2, nitrous oxide, methane, and CFC 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 in the wetland soils. Refrigerators contain CFCs which leads to the ozone depletion in the atmosphere. The burning of the biomass leads to the release of nitrous oxide.
