Question

Which one of the following explains why wind flows near the equator?
(a) The equator gets more heat energy from the sun causing the regions around it to be warmer.
(b) Warm air rises and the cooler air from 30 degrees latitude belt on either side of the equator moves in.
(c) These winds blow from the north and the south towards the equator.
(d) all the above.

Answer 1

(d) all of the above
The light from the sun is at its maximum at the equator than at the poles. Thus, equator receives maximum heat and air around it is warmer. The warm air is lighter, so it rises up and is replaced by the cooler air from 30 degrees latitude belt on either side of the equator. These winds blow from the north and the south towards the equator.
