The plate movements are classified into three types:
(i) Some plates come towards each other and form convergent boundaries.
(ii) Some plates move away from each other and form divergent boundary.
(iii) At times, they may also move horizontally past each other and form transform boundary.
When two plates come together, they are known as convergent plates. They are also known as constructive plates. When two plates move far away from each other, they are known as divergent plates. When two plates coming towards each other collide or burst pass, they are known as transform plate. The movement of plates causes volcanic eruptions, earthquakes, formation of mountains, etc.
