Air flowing from the equator to the poles rises and falls in looping patterns. what are these patterns called?

a. the coriolis effect
b. convection cells
c. emanation cells
d. radiation

Option (B)

Explanation:

The equatorial region receives the maximum amount of sunlight as the sun is directly above it. Due to this, the earth experiences a higher temperature, as a result of which the air in this region becomes warm and less dense. It then slowly rises up towards the upper atmosphere, forming a low pressure zone.  This air when rises up, slowly cools, and after sometime it falls back. This continuous motion of air mass creates convection cells in the atmosphere.

Thus, the correct answer is option (B).
