Question
Given below are two statements Statement I:
The greenhouse effect is the retention of heat in the lower atmosphere due to absorption and re-radiation by clouds and certain gases. Statement II: The anthropogenic greenhouse gases effect is the result of the accumulation of trace gases in the air from human activities. In light of the above statements, choose the correct answer from the options given belowSolution
Greenhouse effect is the trapping and buildup of heat in the atmosphere near Earth’s surface. Some of the heat flowing back towards space from the Earth surface is absorbed by carbon dioxide, water vapour, methane and other gases in the atmosphere and then re radiated back towards Earth’s surface.
