Geologists have uncovered the remains of a massive tectonic plate beneath the Pacific Ocean, a plate that had been hidden for ...

Scientists had determined that ocean acidification enters this danger zone or crosses this planetary boundary when the amount of calcium carbonate—which allows marine organisms to develop shells ...

They represent the least well-studied of the three major plate boundaries, which include divergent boundaries, like East Africa, where plates move apart forming new crust; and convergent ...

The Pacific Ocean is riven with oceanic trenches 3-4 km deeper than the ocean bottom that they cut through. These trenches mark areas where continental plates collide in what are known as ...

There are three types: convergent, divergent, or transform. Boundaries may also be a mixed type, defined by how the plates move relative to each other.

The ocean plate was once the seafloor of Neotethys — an ocean that formed when the supercontinent Pangaea broke up into a northern continent, Laurasia, and a southern continent, Gondwana about ...

An international research team led by the University of Göttingen has investigated the influence of the forces exerted by the Zagros Mountains in the Kurdistan region of Iraq on how much the surface ...

At plate boundaries, cold seawater percolated down through cracks in the crust. There, it was reheated by hot magma and jetted upward through openings that scientists named .

When rock on a convergent plate boundary gets compressed and bent, it builds up elastic energy. When this gets too much, there is an abrupt release as the overriding plate slides up the fault.
