WHAT DRIVES PLATE TECTONIC MOVEMENTS?
Answer: convection currents
Thermal convection currents are generated within the asthenosphere by hot spots around the core of the Earth. These currents cause magma to rise towards the crust and spread before cooling and sinking.
This circulation of magma is the vehicle upon which the crustal plates move.
