Question

The temperature decreases towards poles because:

a. At poles the snow does not melt.

b. The cold regions do not absorb sun rays.

c. The movement of cold wind is towards poles.

d. The sun rays falling per unit areas are less at poles.​

Answer 1

Temperature generally decreases towards the poles because progressively lesser solar energy per unit area falls on the earth's surface as we move to polar regions. Longer the path of the sun's rays, greater is the amount of reflection and absorption of heat by the atmosphere.
