Physical Model of the Earth's Interior Temperature

Yu. P. Petrov, A. V. Gorozhantsev

Abstract


It is shown that the source of the earth's internal heat is a density increase with the depth. The matter density increase causes atoms deformation, which leads to an increase in their kinetic energy. The kinetic energy of atoms determines their thermal motion. The temperature is a physical parameter characterizing thermal motion. Taking into account the chemical composition and phase state of the substance in the introduced model, the temperature dependence on the depth was determined. It allows assuming a sharp temperature change at the boundary between the liquid and solid core. The assumption about the physical causes of volcanoes occurrences along the boundaries of lithospheric plates was made.
