Cause, Origin and Continuation of Plate Tectonics

Authors: Karunakar Marasakatla

Cause of the Earth's surface manifestations appears to be external to the Earth. Gravitational attraction of the galactic center causes the tides to form in the mantle of the Earth when the solar system reaches the nearest position to the galactic center. Pair of troughs takes shape in the mantle adjacent to the tides as the low and high tides in the ocean. Upwelling tides or megablobs breaks the continental crust and disperses the plates towards the troughs on the surface. In the subsequent cycle, when the solar system again reaches the nearest position to the galactic center, megablobs interchange with the troughs and reassemble the continental crust. In other words, two galactic cycles of the solar system makes one Supercontinent cycle on the surface of the Earth. It appears that the Supercontinent cycle started on the Earth around 2800 million years ago. Nucleation of the inner core was initiated in this period with the beginning of the Plate tectonics. Supercontinent cycle continues as long as the solar system revolves around the galactic center in the presence of liquid outer core in the interior and water on the surface of the Earth.
