1 Answer

  • The answer is; T

    The convection currents in the mantle are similar to those of water in a vessel being heated from below.  As the mantle is heated by the core below, the hotter part of the magma begins to rise and the cooler mantle above begins to dive to replace the rising hotter mantle. It is these currents that cause the tectonic plate movements of the earth’s crust.
