Which of the following is not a primary contributor to the greenhouse effect?
Trapping of sun’s heat in the lower atmosphere due to the presence of gases like water vapour, carbon dioxide, methane is called greenhouse effect.
Sun’s radiation is partly absorbed by earth and rest of the radiations are reflected back to the atmosphere which are escaped. But the greenhouse gases form blanket in the atmosphere and trap the radiation from escaping. This causes an increase in earth’s temperature resulting in Global warming.
