However ridge push is also presented in recent research to be a force that drives the movement of plates. Forces deep within the Earth's interior drive plate motion. That's not actually true.
The first is the heat that's generated by radioactive decay within the Earth. Earthquakes do not occur randomly on the Earth. Earthquakes are common in these areas as well.

How are earthquakes detected? The faster-moving Pacific plate converges against the slower-moving Philippine plate. The Naked Scientists Podcast. The pattern of earthquake locations can be explained by assuming the Earth's surface is made up from rigid plates that are in motion relative to each other.
It was once thought that mantle convection could drive plate motions. Tectonic plates do not randomly drift or wander about the Earth's surface; definite, yet unseen, forces drive them. Convection in the Mantle heat driven Ridge push gravitational force at the spreading ridges Slab pull gravitational force in subduction zones.
As it gets further from the heat source, it cools and sinks back to the bottom.
