How and Why Tectonic Plates Move - In the Mantle, the further down you go towards the core, the hotter the Magma is. The Convection current moves in circles because the magma more beside the outer core starts to expand and rise up towards the crust. While the HOT magma is moving up to the crust to cool off, the cooled magma by the crust is moving down towards the bottom. Once this happens, the current takes place over and over again, causing the tectonic plates below the continents to constantly be moving!
