Vedclass · Answer

(C) The Assertion is correct: In the stratosphere,$UV$ radiation causes the photodissociation of ozone $(O_3)$ into molecular oxygen $(O_2)$ and atomic oxygen $(O)$. This is a natural process,but the depletion of the ozone layer is primarily accelerated by chlorofluorocarbons $(CFCs)$.The Reason is incorrect: The ozone hole refers to the thinning of the stratospheric ozone layer,which leads to increased $UV$ radiation reaching the Earth's surface,causing skin cancer,cataracts,and damage to $DNA$. While ozone depletion is a serious environmental issue,it is not the primary cause of global warming or climate change; global warming is primarily caused by the greenhouse effect due to the accumulation of greenhouse gases like $CO_2$,$CH_4$,and $N_2O$.

Assertion : $UV$ radiation causes photodissociation of ozone into $O_2$ and $O$,thus causing damage to the stratospheric ozone layer.
Reason : Ozone hole is resulting in global warming and climate change
