convection currents in the mantle provide the basic driving forces for plate motions.
Plate tectonics.
Motion of plates
Waves is the part of convection current. This is the mantle and is related to plate motions.
The idea that plate motions are caused by electromagnetic forces has not been widely proposed as a mechanism of plate motions. The most accepted mechanism is the theory of plate tectonics, which suggests that plate motions result from the movement of convection currents in the Earth's mantle. Other proposed mechanisms include ridge push, slab pull, and mantle plumes.
convection currents in the mantle provide the basic driving forces for plate motions.
Any and all plate motion causes earthquakes.
Plate motions are driven by convection currents in the Earth's mantle. Heat generated from the core causes mantle material to rise, move laterally, and then sink back down in a cycle. The moving mantle material drags the tectonic plates along with it, influencing their motions and interactions at the surface.

Plate motions produce stress in Earths crust that leads to faults, mountain building, and earthquakes.
