Question

what causes currents to flow between the poles and the equator?
a. uneven solar heating
b. earths rotation
c. tsunamis
d. the coriolis effect

Explanation:

Uneven solar heating causes temperature differences between the poles and the equator. These temperature - related density differences drive the flow of air and ocean currents. Earth's rotation and the Coriolis effect influence the direction of these currents, but the primary cause of the flow is uneven solar heating. Tsunamis are unrelated to the general circulation between poles and the equator.

Answer:

A. Uneven solar heating
