What Causes Tectonic Plates To Move? - WorldAtlas
WebTectonic plates move due to mantle convection, subduction and slab pull. Mantle convection is the movement of magma due to its variation in temperature and density, which also causes the tectonic plates to move. Subduction is when the denser tectonic plate is pushed underneath the other. Slab pull is the gravitational pull that causes the ...
