Seismic waves from earthquakes have always offered a window into Earth’s hidden interior. For decades, researchers believed ...

Recent discoveries offer deeper insight into the movement of tectonic plates. New research has found that variations in rock ...

A rare geological process is tearing the Indian Plate apart deep beneath the surface, scientists have discovered. In a study ...

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 ...

The Earth is made of different layers: the core, mantle and crust. Plate tectonic theory shows that the crust of the Earth is split into plates (pieces of the Earth’s crust). The movement of ...

In the past, such anomalies were usually linked to subduction zones—places where one tectonic plate slides beneath ... old theories—they raise new questions. What are these mysterious anomalies?

Plate tectonics is relatively new, put forth in the last 30 years or so — its forerunner was the now-discarded continental drift theory. The theory states that Earth's outer shell is made up of ...

The tiny Juan de Fuca plate is largely responsible for the volcanoes ... The movement of the plates creates three types of tectonic boundaries: convergent, where plates move into one another ...
