How Do Tectonic Plates Move?

Answer

Tectonic plates move because mantle rocks near the radioactive core are heated and the warmer rocks rise while the cooler rocks sink creating slow, vertical currents within the mantle. This movement of warmer and cooler mantle rocks, in turn, creates pockets of circulation within the mantle called convection cells. The circulation of these convection cells could very well be the driving force behind the movement of tectonic plates over the athenosphere.

Tectonic plates move due to intense heat in the earth's core. The immense heat causes the molten rock in the mantle layer to move. It moves in a pattern called a convection cell that forms when warm material rises, cools, and eventually sink down.
Tectonic plates move because they are floating on liquid mantel which moves due to convectional currents. The plates change in direction of movement; they may come together or move apart. Landforms may be formed in this movements.
Tectonic plates move as a result of the effect of several forces, including gravity, Earth's rotation and heat convection. The denser, more fluid layers beneath the earth are moved by these forces, and they in turn change the positions of the plates.
Tectonic plates can move in three different ways. When the plates move past each other travelling in opposite directions we call it transform boundary. When the plates move away from each other it is called divergent boundary, and when the plates move toward each other and because of this one slides under the other, it is called convergent boundary.
