The theory of plate tectonics describes how plates move. The main driving force is convection currents in the mantle.

The earth is made up of multiple tectonic plates. These plates are propelled by convection in the mantle layer below the crust (lithosphere)

No one will force you to, but it would be wise to include the lithosphere, which is the brittle hard rock of which the tectonic plates are composed of. Crust + rigid uppermost mantle = lithosphere.
There is no "driving force". The tectonic plates created an oceanic/oceanic subvergent boundary where underwater volcanoes formed. The magma comes up through faults and cracks in the lithosphere from the astenosphere and comes out of the volcanoes. I suppose you could say the "driving force" is the heat from the center of the earth heating the rock to a liquid state.
It is the convection on the liquid outer core/ and semi fluid mantle that is responsible for the movement of plates.
The force that is causing movement at this fault is called tectonic force. These forces are generated by the movement and interaction of the Earth's tectonic plates.
