Annotation

It is shown, that continuous changes of angular velocity of rotation of the is plastically-elastic Earth should cause the continuous coupled deformation of a crustal layer, redistribution of masses in a sub-crustal layer and the change of density associated with it, and also, as consequence of these phenomena, a polar pulsation of a figure when polar diameter of the Earth increases and decreases with time. The mechanism of occurrence of deformations of a body of a planet under action of a deforming (centrifugal) variable force is found, the tensors of deformations and pressure are written out, and on the basis of the rheological equations the equations of balance are deduced, and also calculation of the module of change of polar compression and radial displacements is made at real fluctuations of angular velocity of rotation of the Earth. The calculated values have given the quite real changes of compression and radial displacements of the Earth's crust and its other shells. The opposite process is also shown, namely: observed fluctuations of amplitude of the polar compression, leading to respective alterations of the moment of inertia of the Earth, quite correspond to real fluctuations of duration of a day.
