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 ...

For millions of years, Earth’s shifting plates have shaped continents, formed oceans, and built towering mountain ranges. But ...

“Almost all earthquakes happen here, too." The Ring of Fire is the result of plate tectonics − giant moving slabs of rock millions of square miles across that can collide with or pull away from one ...

This study out of the University of Houston points to a new theory that as North America began to split away, the Great Lakes ...

The movement of tectonic plates determines the arrangement of the continents, and they’re constantly in motion. A new video combines a wealth of data and condenses it into a 40-second animation ...

Massive mantle formations, called LLSVPs, have been found to be over a billion years old. These structures, sitting 3,000 km beneath the surface, slow seismic waves, indicating unique physical and ...

Plate tectonics is geology’s Theory of Everything. The realisation in the 1960s that Earth’s crust is made of fragments called plates—and that these plates can grow, shrink and move around ...

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 ...
