Answer 2

Answer:

The plates move because of convection currents in the Earth's mantle. These are driven by the heat produced by the natural decay of radioactive elements in the Earth. Where tectonic plates meet, the Earth's crust becomes unstable as the plates push against each other, or ride under or over each other.
