Following the Earth expansion idea, a new interpretation of Earth has been proposed, taking into account the fact that the initial Earth was small, lacked oceans, and was covered in a solid sialic crust. Geophysical research have proven the presence of a basaltic Mantle beneath the Crust, followed by a fluid Outer Core, which is thought to be made up of liquid iron. Because of the high core temperature, the planet's innermost component, or Inner Core, has not been classified as magnetic, despite being formed of solid iron from which magnetic lines of force emanate. Because the thickness of the Outer Core corresponds to the extent of expansion, the former has opened up as a void zone as a result of expansion. As a result, two solid geospheres separated by a void zone form in the planet's interior, causing a gravitational force in the opposite direction. We read this to mean that the temperature of the solid Inner Core would be sufficiently low due to reverse gravity, and that the Inner Core would thus be a magnet. This viewpoint explains the planet's magnetic characteristics, such as pole reversal and polar wandering. The notion also explains the origins of seas, continental drift, and the nature of terrestrial geospheres, among other things.
