How plate tectonics move?

Answer 1

== == The main features of plate tectonics are: * The Earth's surface is covered by a series of crustal plates. * The plates are composed of crustal rock and solid upper mantle which is called the lithosphere. * Plates are composed of continental and oceanic crust. * The oceanic crusts are continually moving, spreading from the center, sinking at the edges, in a process of recycling. * Rising legs of convection currents beneath the plates create additional plate material at mid-ocean ridges, sinking legs of convection currents swallow old crustal plates at subduction zones. * The heat driving the convection currents is from radioactive decay of material within the Earth and from residual heat from accretion processes during Earth's formation. Convection cells in the magma of the outer core pull the earth's tectonic plates along the surface. These plates can collide and cause earthquakes.
