crust along divergent margins by seafloor spreading. In this way, the total surface of the globe remains the same. This prediction of plate tectonics is also referred to as the conveyor belt ...

John Sclater, a geophysicist at UC San Diego’s Scripps Institution of Oceanography and a member of the first wave of ...

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 ...

Researchers have discovered enormous tube worms and other creatures thriving in cavities beneath the seafloor ... a fast-spreading ocean ridge where several tectonic plates meet off the coast ...

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 ...

But what she uncovered beneath the ocean’s surface would change geology forever. “Tharp’s work certainly provided evidence ...

From the deepest ocean trench to the tallest mountain, plate tectonics explains the features and movement of Earth's surface in the present and the past. The theory of plate tectonics was ...

This advanced undergraduate textbook provides a thoroughly modern overview of plate tectonics and is the perfect resource for a capstone geology course. It presents plate tectonics as a multifaceted, ...

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 ...

From time to time, when Earth's tectonic plates shift, the planet emits a long, slow belch of carbon dioxide. In a new modeling study published in Geochemistry, Geophysics, Geosystems, R.
