Given below are two statements, one labelled as Assertion A and the other as Reason R. In the light of the above statements, choose the most appropriate answer from the options given below.
Assertion (A): Assertion A: The energy of most cyclones dissipates fast after landfall.
Reason (R): Reason R: The surface roughness of land areas is higher than that of oceans.
ABoth A and R are true and R is the correct explanation of A ✓ Correct
BBoth A and R are true but R is NOT the correct explanation of A
CA is correct but R is not correct
DA is not correct but R is correct
Correct answer: (A) Both A and R are true and R is the correct explanation of A — The answer is that both A and R are true and R correctly explains A.
Explanation
★The answer is that both A and R are true and R correctly explains A.
★Cyclones lose their energy quickly once they move over land, so Assertion A is true.
★Land has a rougher surface than the ocean, so Reason R is true.
★This greater roughness creates friction that drains the cyclone's energy.
★So R is the correct explanation of A.
★Cut off from warm ocean moisture and slowed by friction, the storm weakens.
★So the answer is that both A and R are true and R correctly explains A.
