The movement of these plates led to folding, faulting and volcanic activity. These are classified in three categories:
(i) Convergent boundary: When plates come towards each other, it is also called folding movement.
(ii) Divergent boundary: When plates move away from each other, it is also called faulting movement.
(iii) Transform boundary: In the event of coming together, they may collide or may slide under each other.
