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 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 ...

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 ...

Plate tectonics (from the Greek τέκτων; tektōn, meaning "builder" or "mason") describes the large scale motions of Earth's lithosphere. The theory encompasses the older concepts of ...

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

Newly published research has revealed that compositional rock anomalies within oceanic plates caused by ancient tectonics influence the trajectory and speed of the plates as they plunge deep into ...

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 ...

It’s mostly solid rock, moving under extreme pressure, and heat.The planet’s continents and ocean floors are constantly being pushed and pulled.They're divided into seven major tectonic plates ...
