The Rotating Earth and Plate Tectonics

This work explores the nature and origin of the forces responsible for the unrelenting unidirectional movements of continental sized masses away from what was Pangea c. 275 Ma years ago to their present positions.

The analysis given demonstrates that the forces responsible for tectonic movements are related to the rotational velocity of the Earth which is dependent on the Sun’s gravitational pull on the asymmetrical positioning of the Earth’s centre of mass.

The resultant unbalanced rotation gives rise to the Earth’s wobble and the significant circumferential forces that move the continental masses. It is these tectonic movements in which continental and oceanic crusts are continuously forced into the mantle, that forever ensures that the lithosphere is recycled and regenerated.

Furthermore, the offset ‘centre of mass’ gives rise to the generated and tilted N-S principal axis of rotation that applies to all the planets. This action also yields a viable explanation regarding why all the planets (Venus apart) rotate in the same direction as the Sun.

The sight of undisturbed sedimentary rocks on the top of the Bolivian Andes in 2001 prompted this research into the magnitude of the unrelenting forces associated with plate tectonics.
