Surface currents are caused by wind, and affected by the rotation of the Earth and the gravity of the moon (tides). When the oceans are deep, convection within the layers can also affect the flow of currents.
* While wind currents are greatly affected by uneven heating of the Earth's surface, there is no corresponding heating of the ocean bottom by the Sun. So currents do not form spontaneously at depth.
Currents flow between the poles and the equator primarily due to differences in temperature and salinity of the water. Warmer, less dense water moves toward the poles while colder, denser water moves towards the equator, creating a circulation pattern known as the global conveyor belt. The Coriolis effect also plays a role in directing these currents.
The difference in temperatures between the Equator and the north and south poles, plus the rotation of the earth, causes the air currents.

Wind currents flow faster at the poles than at the equator. This is due to the Coriolis effect, which causes the winds to be deflected as they move from high pressure to low pressure areas, creating stronger winds at higher latitudes. Additionally, temperature differences between the equator and the poles contribute to the strength of wind currents.
