Verified Answer
Which of the following will increase the greenhouse effect?1. Increase...
  • The greenhouse effect is a process that occurs when gases in Earth's atmosphere trap the Sun's heat. This process makes Earth much warmer than it would be without an atmosphere.
    - An increase in the albedo of the upper atmosphere reduces the mean atmospheric temperature reducing the greenhouse effect. Hence option 1 is not correct.
  • Albedo is a measure of how much light that hits a surface is reflected without being absorbed,(i) Addition of water vapor in the atmosphere leads to more trapping of solar radiation because water vapor is also a greenhouse gas. Hence option 2 is correct.
    (ii) Cloud Formation: Clouds tend to increase the albedo or reflectivity of the atmosphere. It further reduces the amount of incident radiation on the Earth’s surface thus mitigating the greenhouse effect.
    (iii) Jhum cultivation, also known as the slash and burn agriculture, is the process of growing crops by first clearing the land of trees and vegetation and burning them thereafter. It leads to deforestation and a decrease in the overall carbon absorption by the trees. A higher concentration of greenhouse gases leads to the greenhouse effect. Hence option 3 is correct.
