Air tends to move from

the equator to the poles

conduction

cold air rising and warm air sinking

radiation

Option (a) is the correct answer.

Explanation:

It is known that equator is closer to the sun, therefore, region around the equator is warm. As a result, air near the equator is also warm.

Hence, molecules of air expand more rapidly whereas air near the poles is cold as poles are away from the sun.

Thus, we can conclude that air tends to move from the equator to the poles.
