I will give you medal and fan you if anyone answers this Explain how these convection currents cause the crust of the Earth to move.

OpenStudy (anonymous):

The Earth's crust is in the form of plates which float on the dense liquid magma of the mantle. When there is a current in the magma, it pushes against the crust floating on top of it. Tectonic plates are very large and heavy, so they don't move easily, but they do move.
