Assertion: UV radiation causes photodissociation of ozone into O2 and O, thus causing damage to the stratospheric ozone layer.
Reason: Ozone hole is resulting in global warming and climate change.
(a) If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.
(b) If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.
(c) If the Assertion is correct but Reason is incorrect.
(d) If both the Assertion and Reason are incorrect.
(e) If the Assertion is incorrect but the Reason is correct.
(c) If the Assertion is correct but Reason is incorrect.
Explanation:
Ozone in stratosphere is responsible for the protection of earth from high energy UV rays i.e. it acts as life saving screen. Ozone layer found in troposphere protects from warming effect of earth.
Due to human activities, the ozone layer in the stratosphere starts thinning, which is also called ozone hole. Ozone hole is resulting in rain failure, increase in radiation, cancer (skin) and reduction in crop production.
