What Causes Tectonic Plates to Move?

Answer

The movement of tectonic plates is caused by the flow of magma beneath the earth's crust's surface. The movement may result in formation of valleys or eruptions of volcanoes.

Tectonic plates 'float' on the molten rock magma. As the molten magma gets heated up, the heat causes convection currents, a movement of rising and sinking caused by heat, inside the molten magma. The magma rises and spreads out across the surface, then cools and sinks, making the plates to move.
The causes of the movement of plate tectonics is the extensive heat in the core of the earth that makes the molten rock found in the mantle layer to move. The movement of plates is divided into transform, divergent and convergent movements.
Since tectonic plates are made of crust and mantle rock they are lighter and less dense. The materials under the Earth cause motion and as a result the tectonic plates begin to move.
