Question

Why are hill stations cooler than plains?

Answer 1

Atmosphere of the Earth gets heated up as a result of heat radiated from the Earth's surface. The water vapour and dust particles present in the air absorb the heat and reflect it back into the atmosphere. The air is dense on the plains as compared to the hill stations where air is rare due to increased altitude. Therefore, atmosphere gets heated up more near the plains as compared to the hill stations.
