aCurrents in Earth’s mantle called convection currents transfer heat in Earth’s interior. It is thought that this transfer of heat energy moves plates. 潮流在地球的披风叫的对流调动热在地球的内部。 它被认为热能这调动移动板材。[translate] ...
and rises upward. This pushes cooler rock downward. The cycle repeats, creating convection currents. This churning motion in the mantle appears to be a major factor in plate movement. The plates—and thus the continents—are still moving today, at an average rate of less than five inches per...

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 coincides with the present location of similarly complex patterns of intense positive gravity anomalies produced by rising and divergent mantle convection. Apparently the convection caused the breakups and the location and intensity of the convective pattern have not changed since Mesozoic time....
