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.

Most geologic activity stems from the interplay where the plates meet or divide. The movement of the plates creates three types of tectonic boundaries ... connects the world's oceans, making ...

Plate tectonics is the theory that Earth's outer ... Pangaea began to rift, or split apart, around 200 million years ago. Oceans filled the areas between these new sub-continents.

The Pacific and Australian plates collide and interact in complex ways around New Zealand ... At divergent boundaries, plates move away from each other and form mid-ocean ridges or major rift ...

But as far as we know, no other bodies in the solar system exhibit plate tectonics today. Why is our world different ... these separate plates that move around with that convective mantle ...

Today, the upheavals of plate tectonics continually reshape Earth. When this began is much disputed - and we can’t fully ...

These zones include: the Pacific Ring of Fire around the Pacific Ocean the Mid ... more than 3,200 km from the nearest plate boundary. This is explained by the 'hotspot' theory.

These plates can be oceanic, meaning they're found mainly under the ocean, or continental, and mainly found under land. And they are moved around, constantly fuelled by energy from the very hot ...
