If the clues are Cherrapunji, Mawsynram, and orographic rainfall, which hill group is correct?
Answer and explanation
Correct answer: Khasi Hills
The governing concept is orographic rainfall in the hills of Meghalaya. Cherrapunji and Mawsynram are located in or near the Khasi Hills, where moisture-laden winds from the Bay of Bengal are forced to rise against the steep southern escarpment. As the air rises, it cools, condensation increases and very heavy rainfall occurs. Therefore option A, the Khasi Hills, correctly matches all the clues. The Palani Hills are in southern India, the Aravalli is an old range in western India, and the Maikal Hills are part of the central Indian highlands. These alternatives do not explain the famous concentration of extreme monsoon rainfall in the Meghalaya region.
