The process of heat transfer thought to be responsible for the movement of the lithospheric plates on the surface of the earth is

Convection

Explanation:

Difference in temperature induces convection currents. The mantle material close to Earth's core is quite hot in comparison to the one close to the lithosphere, which is cooler. Earth's convection currents are very slow in movement. They flow at rates of a few centimeters per year. It is believed by scientists that the movement of mantle material carries the plates of the lithosphere with it which causes the plates to move.
