Uneven solar heating
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.
Unequal heating between the equator and the poles
Temperature difference
earth's tilt (apex)
The difference in temperatures between the Equator and the north and south poles, plus the rotation of the earth, causes the air currents.

Earth's tilt

Warm currents move from the equator to the poles, and the cold currents move from the poles to the equator. :D

Yes, convection currents connect the poles all the way to the equator.
