Answer:
Yes
Explanation:
Heat in the mantle comes from the Earth's molten outer core, decay of radioactive elements and, in the upper mantle, friction from descending tectonic plates. ... While conduction seems the more obvious method for heat transfer, convection also occurs in the mantle.
They moved the same by convection currents, convection currents are caused by radioactive decay in the Earth’s core, the convection currents move the plates
