The movement of the tectonic plates is caused by

We have that  the tectonic plates  are formed by the Convection of Currents in the Earths's Mantle

i.e The Dynamics of Current in and around the Earths Mantle brings about The  tectonic plates

From the question we are told

The movement of the tectonic plates is caused by

Generally

Tectonic plates these refers to the Spheres that are found in the uppermost Mantle of the Earth .The Tectonic plates are also called the Litosphere .

The Motion of the Plates about the axis causes the Tectonic demarcations which are Know as the

Now these Plate are formed by the Convection of Currents in the Earths's Mantle

i.e The Dynamics of Current in and around the Earths Mantle brings about The  tectonic plates

The force that causes most of the plate movement is thermal convection, where heat from the Earth's interior causes currents of hot rising magma and cooler sinking magma to flow, moving the plates of the crust along with them.
