As our planet cooled down, the outer layer hardened to form crust. But the uneven cooling of the inner layer underneath the crust resulted in molten plastic like formation known as magma. The crust glides slowly over the magma like a jigsaw puzzle. This movement resulted in collision of two large landmass (or parts of puzzle) known as GONDWANALAND and LAURASIA. The collision resulted in the sea bed of Tethys Sea to rise upward which lead to formation of The Himalayas.
Isn't that amazing!!. Even today the crust glides on top of magma, resulting in the upward movement of Himalayas.
