convection currents in the mantle provide the basic driving forces for plate motions.

The entire crust (or outer layer) of the planet Earth is composed of plates, and the movements of those plates are described by the science of plate tectonics.

the Lithosphere or Lithospheric Plates
The motion in the mantle is known as convection currents which helps move earth's slabs, known as plates. Convection occurs in the upper mantle known as the asthenosphere.

Moving plates in the earths mantle.
The asthenosphere.
Tectonic Plates float on top of the earths mantle, the earths mantle is made up liquid which is always circulating.

The process of 'earth plates moving' is Alfred Wageners theory of continental drift. This theory proposes that convenction currents in the earths mantle provides a 'cushion' on which the plates can move.
