For an ocean such as the Atlantic to stop growing and shut itself off, new subduction zones must form within it – areas where ...

Off the coast of Chile and Peru, along the entire western length of South America, the seafloor takes a sharp, steep plunge ...

Researchers found that an inactive subduction zone under the Strait of Gibraltar may begin migrating into the Atlantic Ocean, commencing the shrinking process. The zone also brings a higher risk ...

What happens, then, to keep the Earth the same size? The answer is subduction. In locations around the world, ocean crust subducts, or slides under, other pieces of Earth's crust. The boundary ...

In subduction boundaries, sediment is shed off the volcanic mountains, and some makes its way to the ocean to be deposited in shallow and deep water marine environments. This sediment is poorly ...

Bringing a novel approach to a classic problem, researchers have revealed how changes in ocean chemistry over the past 2 billion years have left an imprint on volcanic rocks formed in island arcs.
