Gravity of The Sun, The Main Force Operating That Changes The Location of The Earth’s Axis of The Earth’s Mantle And, Accordingly, The Location of The Equator

The force of gravity of the sun on the earth, when the axis of the earth is found at a specific angletowards the sun in the summer and the winter, moves the earth’s mantle, including the axis of the earth’s rotation.This force is the main thing that changes the location of the axis of the earth’s rotation on the mantle of the earthand, to a minor extent or not at all, causes a change in the angle of the earth’s rotation in relation to the sun, and tothe earth’s ecliptic plane.
