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 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 ...
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 ...

Plate boundaries may experience higher temperature and stress than previously thoughtYet 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.
Map of the Word with lines marking boundaries of tectonic plates. Plate tectonics is a theory that explains how Earth’s lithosphere—its upper mantle and crust—is split into sections called ...
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 ...
