Another theory is that gravity is pulling the older, colder, and thus heavier ocean floor with more force than the newer, lighter seafloor. Whatever drives the movement, plate tectonic activity ...

 These have indicated that what is today's mountain peak, was once the sea floor on ancient Earth ... initially believed to have formed during tectonic plate collisions, surprisingly exhibit ...

The mid-ocean ridges mark the lines along which the Earth is turning itself inside out through the process of plate tectonics. Advances in technology are helping to reveal the intricate details of ...

The motion pushes along the tectonic plates, causing them to rub against ... After about three million years, scientists ...

Geologically active, mid-ocean ridges are key sites of tectonic movement, intimately involved in seafloor spreading. This coursebook presents a multidisciplinary ... Accessible to students and ...

The Earth is made up of different layers: Therefore, instead of tectonic plates moving because of the convection currents, evidence suggests it is the plates that drive the convection. Slab pull ...

The movement of the plates creates three types of tectonic boundaries: convergent, where plates move into one another; divergent, where plates move apart; and transform, where plates move sideways ...

Plate tectonics is relatively new, put forth in the last 30 years or so — its forerunner was the now-discarded continental drift theory. The theory states that Earth's outer shell is made up of ...
