The convection currents running through the asthenosphere are widely believed to be the source of movement of the tectonic plates.

The Asthenosphere, a.k.a. the Plastic Mantle.
The softer layer below the lithosphere is the asthenosphere. The asthenosphere begins at a depth of approximately 150 km. It has convection currents that arise from the heating and subsequent rising of material from the lower asthenosphere. These convection currents drive the movement of lithospheric plates at the surface, and are the cause of tectonic activity.
