Explaining the Earth System: An Approach Based on Earth Expansion Theory | Chapter 9 | Modern Advances in Geography, Environment and Earth Sciences Vol. 6

 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.

The King is Naked: Prevailing State of Art in the Present-Day Earth Sciences | Chapter 11 | Challenging Issues on Environment and Earth Science Vol. 1

The popular Danish author for children, Hans Christian Andersen, told the storey of two weavers who persuaded the king and his noblemen that their new dress would not be visible to the scoundrels[1]. So, everyone who saw the naked king decided that the new outfit he was wearing was fantastic. In the field of present-day earth science, almost an identical condition prevails. For instance, despite the strong and rigid state of the mantle, where convective movement is not possible, Earth scientists assume that continental blocks or plates are shifting due to mantle convection and that a geo-dynamo operating in the deep interior of the Earth often generates the planet's magnetic phenomena. The author here points out certain blatantly false concepts which, in the field of geological sciences, are causing utter confusion, especially concerning global tectonics. "Reject plate tectonics and save Earth sciences" is the subject of the paper.
