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.

The Earth's outermost layers (the lithosphere) are broken into about a dozen or so plates. These thin, wide tectonic plates move around on the globe independent of one another. Most volcanoes and ...

These ancient buried "super-continents"—known to scientists as large low-seismic-velocity provinces (LLSVPs)—were found ...

Download a chart to use in class and an activity for practicing with these concepts: Tectonic Basins chart and activity Here is a diagram to help you understand how the tectonic basins are related to ...

Where convection currents push plates together, destructive plate boundaries (margins) are formed. Constructive plate margins close constructive plate marginAn area where two tectonic plates are ...

Yet because earthquakes originate tens of kilometers below Earth's surface at plate boundaries, the effects of temperature and the magnitude of stress are poorly understood and hotly debated.

Whatever drives the movement, plate tectonic activity takes place at four types of boundaries: divergent boundaries, where new crust is formed; convergent boundaries, where crust is consumed ...

Designed for middle- and high-school science educators to broaden their own knowledge and use with students, the course weaves together activities, videos, and classroom-ready materials into a primer ...

The movement of the plates creates three types of tectonic boundaries: convergent, where plates move into one another; divergent, where plates move apart; and transform, where plates move sideways ...
