Assertion (A): The Palakkad Gap (Palghat Gap) acts as a major climatic and biotic corridor between Kerala and Tamil Nadu across the Western Ghats. Reason (R): It is a wide low-altitude mountain pass formed by block faulting, which allows moisture-laden southwest monsoon winds and dry easterly winds to cross between the Arabian Sea coast and the interior plains. Which of the following is correct?
A. Both (A) and (R) are true, and (R) is the correct explanation of (A).✓ Correct Answer

D. (A) is false, but (R) is true.
💡 Solution & Explanation
The Palakkad Gap functions as a crucial climatic and biotic corridor because its low-altitude terrain allows moisture-laden southwest monsoon winds and dry easterly winds to cross between the Arabian Sea and interior plains. Both assertion and reason are factually accurate, with the physical topography of the gap directly explaining its role in shaping regional rainfall and vegetation patterns. Geographic gaps in mountain ranges often serve as vital corridors for cultural migration and ecological exchange.
