biaxial and triaxial ellipsoid

Purpose. The purpose of this work is to show how redistribution of masses occurs as a result of gravity-rotational and endogenous forces in the evolutionary self-development of the planet, which leads to the transformation of the lithosphere from the sphere to the biaxial and then to triaxial ellipsoid, and vice versa; and changes in compression and the movement of the pole in geological time. Determine the deformation of the figure of the lithosphere due to the reorientation of the figure's pole. Methodology.

Aim. The aim of this work is multifold: to show, at a qualitative and approximately quantitative level, how the process of the evolutionary self-development of the planet is a result of the action of gravitational-rotational and endogenous forces, and to show that mass redistribution leads to the transformation of the figure of the lithosphere from a biaxial ellipsoid to a triaxial and vice versa; to show changes in compression, axial rotation speed, and pole displacement in geological time; and to determine the valid mass forces that cause the dynamics of the stress state
