MODEL OF THE HOT EXPANDING EARTH
Model of the Hot Expanding Earth is proposed. The Earth expansion is confirmed by a fact that continents movement traceable by paleomagnetic data is theoretically possible only on its (Earth) increasing surface. According to the model the planet substance (mainly hydrogen, water and oxide of silicon) in the moment of its formation was in the state of hot overcondensed vapor occupied the volume equal to the outer core volume. Two exothermal constitutional changes such as condensation and crystallization participated directly in the planet evolution. The hot Earth cooled after formation. At the early stage of the Earth evolution the process of mantle matter crystallization had determined the cooling rate of the planet substance and the expansion was slow. When the thickness of the outer core liquid layer has become sufficient for origination of the outer core convection, the conventional heat interchange from the inner core to mantle became possible, and the Earth radius increasing went much faster. The article contains quantitative estimations of the Earth parameters changes (planet radius, radiuses of inner and outer core, temperature, chemical composition, density, etc.) at various stages of its evolution. The concept of the Expanding Earth received an indirect confirmation as a result of experiments on the Moon gravity field research (GRAIL mission). These experiments showed that the Moon expanded at the early stage of its evolution. Estimations of magnitude and the Moon expansion time ensuing from the author model coincide with data obtained by carrying out the GRAIL mission. The author model enables researchers to evaluate the quality of water exuded on the Earth and the Moon during the mantle crystallization.
Key words: Hot Expanding Earth, GRAIL mission, Moon expanding.
