We all know that Earth revolves around Sun as all the planets in our solar system but the hidden fact is that there is also a movement within the spheres of earth crust with the help of the force that is generated within and inside from the Earth’s core.
Like a cabbage which is made up of layers of leaves, in the same way our planet Earth is also made up of, and is also surrounded from its inside with the layers called Crust, Core and Mantle where crust is divided into two layers, Continental Crust and Oceanic crust which is commonly called as lithosphere wherein Oceanic crust is denser and stronger than the continental crust which makes Continental crust to flow above the asthenosphere layer which is present in Mantle.
