How are the continental plates formed and how are they eventually destroyed?

● Continental plates are formed due to the cooling of magma.

● Continental plates are moving continuously. The shape and size of the Earth cannot change due to this constant movement of the continental plates. So, the plates form layers. This leads to the formation of mountains and trenches.

● Assume, two plates collide together during their shifting. So, one of the plates moves down under the other. The plate which is underneath gets heated due to the Earth’s heat and melts. Thus, the continental plates are destroyed.

● When 2 plates are pushed away from each other, molten magma comes out and this leads to the formation of a new crust.
