Earths crust is broken into plates called tectonic plates. the plates move bc of convection currents in the earths mantle. convection currents are the movement caused with a liquid by the propencity of hotter and less dense matter to rise, and colder, thicker material to sink under the effect of gravitational pull, which as a result results in the transfer of heat. As a result these are moved by the heat composed by the common natural blight of radioactive component in the earth.
