Take a deep dive into the ocean’s secrets. ExtremeTech reveals its hidden layers and life forms. Discover the depths of our ...

The answer is subduction. In locations around the world, ocean crust subducts, or slides under, other pieces of Earth's crust. The boundary where the two plates meet is called a convergent boundary.

than the ocean floor. When two land masses meet, on the other hand, neither will slide under the other. Instead, the two crush together at what is known as a collisional boundary. They crumple and ...

pulling oceanic plates beneath continental margins and creating complex geological interactions. At the boundary between ...

At a destructive boundary the plates are moving towards each other. This usually involves a continental plate and an oceanic plate. The oceanic plate is denser than the continental plate.

Sometimes these vast continental seas have been very shallow ... and contains many black minerals and volcanic rock fragments. In continent-ocean subduction boundaries, this sediment is deposited in ...

Gather your supplies! In this episode we will use everyday materials to learn about tectonic plates and fault lines.

Some examples of recent and ongoing research topics include the study of continental and oceanic extensional tectonics, ancient arc-continental collisions, active and ancient accretionary terranes, ...

A Nankai Trough megaquake is expected to strike along the boundary between a continental plate and an oceanic plate. But the Jan. 22 temblor occurred inside the oceanic plate, which lies at a ...

This is called a destructive or convergent plate boundary. When the plates collide, the denser plate, usually the oceanic one, is forced underneath the continental plate. The force of this ...
