Answer:

Mantle convection

Explanation:

The source of the force that moves tectonic plates along plate boundaries is as a result of the mantle convection.

  • Heat energy produced in the mantle especially from radioactive decay is a very important source of internal heat that drives plate motion.
  • Denser and cold materials close to the over-riding lithosphere above sinks deep into the mantle.
  • Hotter and lighter materials rises to the surface.
  • This sets up a convection cell by which the plates above are driven.
