Question

why do the plates move?​

Answer 1

These plates move around very slowly -just a few millimeters each year, because of the movement of the molten magma inside the earth. ... The movement of the plates causes changes on the surface of the earth.....these are called lithospheric plates .

Answer 2

Answer:

Plates at our planet's surface move because of the intense heat in the Earth's core that causes 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.
