Explain why the plates move across the earth's surface

  • The plates move, floating on the soft rock, beneath the lithosphere.
  • They are moved by the currents created in the magma of the mantle which then partly sticks to the crust and moves the plate
  • These currents being created by gravity and the Earth's magnetic field, as part of this magma is molten iron
  • Most earthquakes, volcanoes and mountain forming takes place at plate boundaries.
