Plate boundaries are where the action is. A large fraction of all earthquakes, volcanic eruptions, and mountain building occurs at plate boundaries. It is also where most of the people on Earth live.

These convergent boundaries also occur where a plate of ocean dives, in a process called subduction, under a landmass. As the overlying plate lifts up, it also forms mountain ranges. In addition ...

Four types of plate tectonic activity are demonstrated in this feature. Keep an eye on the map to see where in the world the activity takes place. Also known as spreading boundary, a divergent ...

The plates move relative to each other. This is called plate tectonics. Tell them they will learn about the three different kinds of plate motion in this lesson. 5. Tell your students that now ...

Scotese studies how plate tectonics and a warming climate will change Earth's appearance in the future, and he has made multiple animated maps based from his research. For more animations from ...

Plate tectonics is the theory that Earth's outer layer is made up of plates, which have moved throughout Earth's history. The theory explains the how and why behind mountains, volcanoes ...
