ABSTRACT: The rotation of the physical
Earth not only obeys the law of conservation of angular momentum but follows
also the three-finger rule of the right-handed system. The reference frame in
the Earth is most essential. The generalized Eulerian equation of motion or the
Liouville equation is to represent global geodynamics in general, which is examined
directly through the observation of the Earth’s rotation and surface motions,
with no additional assumptions after fundamental physics. Rotational
acceleration, polar motion, plate tectonics, and seismicity observed on the Earth’s surface indicate that the Earth’s angular momentum is
perturbed and adjusting independently of external torques. (For more information,please refer to the PDF.)
