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 ...

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 ...

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.

Plate tectonics give Earth its mountains, earthquakes, continental drift and maybe even helped give rise to life itself. But do other planets in the solar system have them too?

Understanding plate tectonics is key to grasping how the Earth’s geology works and how oceans and continents came to be.

To learn why, where, and how earthquakes happen, you need to familiarize your students with the interior of the Earth and a model called plate tectonics ... cracks all around the egg.

According to plate tectonics theory, Earth's outer shell is divided into multiple plates that slowly glide over the mantle. This slowly changes Earth's surface over time by merging, or separating ...

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 ...
