Here following the Earth expansion theory, a new interpretation on Earth has been put forward, bearing in mind that the original Earth was small, ocean-less and covered with a solid sialic Crust. Geophysical studies have confirmed that below the Crust there occurs a basaltic Mantle, followed by fluid Outer Core - considered to be composed of liquid iron. The planet?s inner-most part or Inner Core, though composed of solid iron from where magnetic lines of force emerge, has not been reckoned as magnetic because of high core temperature. Here we have shown that since the thickness of the Outer Core matches with the extent of expansion, the former has opened up as a void zone due to expansion. Hence, in the planet?s interior two solid geospheres separated by a void zone occur which in turn would give rise to a force of gravitation in the reverse direction. We interpret here that because of reverse gravity, temperature of the solid Inner Core would be sufficiently low and the Inner Core, therefore, is a magnet. This view explains magnetic features of the planet, including pole reversal and polar wandering. The concept additionally explains origin of oceans, continental drift, nature of terrestrial geospheres, etc.
