Question

what moves the tectonic plates​

Answer 1

Explanation:

There are three types of tectonic plate movement :

Convergent plate movement

When two plates move towards each other they collide.As the plates collide some crust is destroyed.Hence it is also called as destructive plate boundaries.

Divergent plate movement

When two plates move away from each other they are called diverging.The magma from the mantle underneath the crust rises up, cools and solidifies and thus new crust is formed.Hence it is also called constructive plate boundaries.

Transform plate movement

When two plates move horizontally past each other.They form transform boundary. When they occur, crust is neither created nor destroyed along it.Hence they are also called conservative plate boundaries.

Answer 2

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. As the cooled material sinks down, it is warmed and rises again.
