The magma carries the attached crust with it as the magma moves because of convection currents.
Explanation:
The idea is that the heat from the earth's interior causes convection currents in the magma. The heat causes the some of the magma to rise toward the surface. When the magma reaches the surface it spreads out and moves away from the hot spot. Then as the magma cools it is pulled down and drops down back down to the interior of the earth.
The magma becomes attached to crust as the magma cools. The attached crust moves with the magma as the magma is moves by the convection currents.
The convection currents in the magma moves the attached crust of the tectonic plates.
