Abstract: The global torsion tectonic system does not only involve the surface but also the interior of the spherical Earth. This paper describes emphatically the mechanism of the coupling of twisting of the Earth's individual spherical layers, that controls the plate tectonics.
There is an inclination of 62°36' between the Earth's equator and the galactic equator. When the galactic center moves from the north to the south of celestial sphere, the plastic mantle of the Earth will migrate towards its southern hemisphere and the continental plate will drift to its northern hemisphere under the control of the centrifugal force of revolution. Such a process will lead to the asymmetry of southern and northern hemisphere and a twisting of the two hemispheres. So there is a correpondence between the rhythm of the Earth's continental drift and the cycle of spirals of the galaxy. In solar system planets (or satellites) which revolves in the same way as the Earth will undergo a synchronous twisting.
