The teacher is demonstrating a convergent plate boundary.
Explanation:
A is correct because this type of boundary is characterized by two or more plates moving toward each other and pressing each other, with the smaller ones gradually moving below the larger ones.
B is not correct because the earthquakes are a consequence of the plate boundaries and their activity.
C is not correct because the equator is simply an imagined line that is separating the northern and southern hemispheres.
D is not correct because the divergent plate boundaries are the ones where the plates are moving away from each other.
