Vedclass · Answer

(B) The Assertion is correct because global warming is a well-documented phenomenon caused by the increase in the concentration of greenhouse gases like $CO_2$,$CH_4$,and $CFCs$ in the atmosphere.These greenhouse gases trap heat by preventing the escape of long-wave infrared radiations into space,leading to a rise in global temperatures.The Reason is also a scientifically correct statement regarding the depletion of the ozone layer,which allows more $UV$ radiation to reach the earth's surface.However,the depletion of the ozone layer is not the cause of global warming; therefore,the Reason is not the correct explanation for the Assertion.
