The image below models the activity that occurs between two tectonic plates What does the model demonstrate?
A.
Each plate is rapidly expanding due to the convection currents in the asthenosphere.
B.
Convection currents in the asthenosphere keep each plate in one place so that they do not collide.
C.
Each plate is pulled straight downward due to the convection currents in the asthenosphere.
D.
Convection currents in the asthenosphere contribute to the force pushing plates toward each other.
