What causes Earth's lithospheric plates to move?
The lithosphere covers the outside of our planet and is made up of the crust and upper mantle. The lithosphere sits on top of the asthenosphere, which is hot, ductile and features convection currents. These convection currents put strain on the lithosphere and caused it to crack into plates.
Answer and Explanation:
The convection currents are also responsible for the movement of the plates. In a convection current hot material rises up, cools and falls down again. This flowing movement of the asthenosphere pulls the lithospheric plates along.
