Answer: Option (B)
Step-by-step explanation: Wind pattern in the earth shows the same convection current mechanism like the one that takes place in case of plate tectonic movement.
In the equatorial region, the air becomes warm, less denser and eventually rises up to the atmosphere and falls at the tropics (30° N and S latitude) of both the hemisphere.
Similarly at 60° latitude in both the hemisphere, the warm air rises up and converges at the poles of the two end.
Thus, the wind pattern in earth is comprised of convection current mechanism.
