What could be a possible explanation why tectonic plates do not all move in the same direction?

A. The magma moves the plates in the same direction, but slab pull makes them move away from one another.

B. The magma moves in the same circular path, but the plates bounce against each other and change direction.

C. The magma moves in "cells," which circulate in different directions, moving the plates in more than one direction.

D. The magma's movement in the mantle is highly erratic and causes the plates to move in circles.

C. The magma moves in "cells," which circulate in different directions, moving the plates in more than one direction.

magma movement is based on convection currents so whichever direction they move in the plates will move with them.
