Describe the hypotheses scientists use to explain the movement of tectonic plates. which hypothesis do many scientists think may explain the great force needed to move plates

Scientists use four hypotheses to explain the movement of tectonic plates:

Many scientists think that the heat in the rising convection currents in the Earth’s mantle provides the energy to move the plates. The hot material becomes denser as it reaches the surface and cools. It flows downhill by gravity and eventually sinks again.

where's the diagram?

they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.
