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.

Heat is transferred from the equator to the poles through a mechanism called atmospheric circulation. Warm air rises at the equator, moves towards the poles, cools, and then sinks at the poles. This circulation, combined with ocean currents, helps distribute heat around the globe.

That force is caused by the convection currents in the magma below the plates.

Convection Current
The liquid or gas which transfers the heat can circulate round and round between the hot and cold regions. The flow of liquid or gas is called a convection current. Convection currents are caused by changes in density.

When a convection current detector comes near a heat source, it will detect the movement of air or fluid caused by the temperature difference. This movement creates a convection current around the heat source, which the detector can measure to indicate the presence and intensity of the heat source.

The thermal convection that drives plate motion is caused by the movement of molten rock in the mantle. Heat from Earth's core causes the mantle to circulate in a convection current, which in turn drags the overlying tectonic plates along with it, driving plate motion.
I learned what convection means in science class.
A convergent plate boundary is caused by a downward convection current in the mantle. At these boundaries, tectonic plates move towards each other, resulting in subduction zones or collision zones, where one plate is forced beneath the other.
That is the current theory of plate tectonics.
The circular motion is called convection current.
