which best describes how ocean currents are created?
a. wind differences between the poles and the equator because of the suns light lead to ocean currents.
b. heating differences between the poles and the equator because of the sun lead to convection.
c. earths rotation disturbs ocean waters, leading to a system of currents between the poles and equator.

Explanation:

Ocean currents are mainly driven by heating differences between the poles and the equator due to the sun's energy. This heating - difference causes density variations in seawater, which in turn leads to convection currents in the ocean. Wind differences can also influence ocean currents but are not the main cause. Earth's rotation affects the direction of ocean currents (Coriolis effect) but is not the primary cause of their creation.

Answer:

B. Heating differences between the poles and the equator because of the sun lead to convection.
