Earth interior can be divided into three main layers namely the core, the mantle and the crust. Each of these layers can be further divided into two parts which are the inner and outer core, the upper and lower mantle and the continental and oceanic crust. According to the theory of plate tectonics, the Earth's crust and upper mantle are broken into moving plates. Both the inner and outer core are made up of mostly iron and a little bit of nickel
