Earth's tilt
The difference in temperatures between the Equator and the north and south poles, plus the rotation of the earth, causes the air currents.

Yes, insolation, which is the amount of energy a surface receives from the sun in kilowatts, at is less at the poles than the equator. This causes convection and in turn causes wind and ocean currents, but other influences, such as Earth's rotation and topography are also responsible.

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.

The high solar intensity at equatorial latitudes causes intense heating at the equator, which produces powerful convection currents called Prevailing Winds. The Doldrums are where the prevailing winds at the Equator die.
Convection currents.
The convection currents running through the asthenosphere are widely believed to be the source of movement of the tectonic plates.
If the Earth did not rotate, convection currents would move in one straight path, from the equator to the North Pole and back again. The rotation of the Earth causes this path to be skewed so that currents move in smaller circles between these areas. This is called the Coriolis Effect.
