Vedclass · Answer

(D) The atmosphere surrounding the earth acts like the glass walls of a greenhouse. It allows incoming solar radiation to pass through but prevents the long-wave infrared radiation emitted by the earth's surface from escaping into space.Thus,the atmosphere acts as a greenhouse,trapping heat. The gases in the atmosphere most responsible for keeping the earth's surface warm are $CO_{2}, CH_{4}, CFCs, N_{2}O$,and water vapor.Statement $I$ is correct because greenhouse gases absorb infrared radiation and re-emit it towards the earth,causing heating.Statement $II$ is correct as $CO_{2}, CH_{4}, CFCs$,and $N_{2}O$ are the primary greenhouse gases.Statement $III$ is correct because an increase in the concentration of these gases leads to an increase in the mean global temperature,a phenomenon known as global warming.Therefore,all three statements are correct.
