Inner Core, Outer Core, Mantle and Crust. The crust and upper mantle core are called lithosphere. Now this 50-km thick layer is divided into several sections, also called tectonic plates . That is, the upper surface of the earth is made up of 7 tectonic plates. These plates are never stable, they are constantly moving, when these plates move towards each other, they collide. Many times these plates are also broken. A large amount of energy is released by their collision, this causes a stir in the area. Many times these tremors are of very low intensity, so they are not even felt. While sometimes they are of such high intensity, that the earth explodes.
