Assertion: Ozone depletion occurs more rapidly in polar regions compared to other regions.
Reasoning: Low temperatures in polar regions accelerate the reaction between chlorine and ozone, leading to rapid depletion.
Both Assertion and Reasoning are true and Reasoning is the correct explanation for Assertion.
Both Assertion and Reasoning are true but Reasoning is not the correct explanation for Assertion.
Assertion is true but Reasoning is false.
Assertion is false but Reasoning is true.
Answers (1)
The Assertion that "Ozone depletion occurs more rapidly in polar regions compared to other regions" is true. This is because the polar regions experience extreme cold temperatures, especially during the winter months, which creates polar stratospheric clouds. These clouds provide a surface for chemical reactions that convert inactive forms of chlorine into forms that can destroy ozone. This results in a more rapid depletion of the ozone layer in the polar regions compared to other regions.
The Reasoning that "Low temperatures in polar regions accelerate the reaction between chlorine and ozone, leading to rapid depletion" is also true and provides the correct explanation for the Assertion. The low temperatures in the polar regions increase the amount of polar stratospheric clouds, and this leads to the formation of more reactive forms of chlorine, such as chlorine nitrate and chlorine peroxide. These reactive chlorine compounds then break down the ozone molecules at a much faster rate, leading to rapid ozone depletion.
Therefore, Option 1 is the correct answer, as both the Assertion and Reasoning are true, and Reasoning provides the correct explanation for the Assertion.
