The clues Cherrapunji, Mawsynram, and orographic rainfall indicate which hill region?
Answer and explanation
Correct answer: Khasi Hills
The governing concept is orographic rainfall, in which moist air is forced to rise over a mountain slope. Cherrapunji and Mawsynram are located in the Khasi Hills of Meghalaya, where the funnel-shaped relief and exposure to moisture-bearing monsoon winds promote exceptionally heavy rainfall. As the air rises, it cools, water vapour condenses, and rain falls on the windward slopes. Therefore option A is the correct hill region. The Palani Hills are in southern India and are not identified by the Cherrapunji–Mawsynram pair. The Aravalli range lies mainly in the drier north-west, while the Maikal Hills are in central India; neither has this distinctive association with Meghalaya’s extreme monsoon rainfall.
