How do convection currents cause the plates to move?
the convection currents cause the plates to move by the magma underneath the lithosphere as it heats it rises and as it cools it drops this is becuase as magma heats it expands and becomes less dense and as it cools it becomes more dense. This process creates a convection cell which move in either a clock wise motion or a counter clock wise motion pulling the plates away from each other.
