Researchers have discovered a pattern where diamonds explode from deep beneath the Earth’s surface in huge, volcanic “fountains.” Diamonds form approximately 90 miles deep in the Earth’s crust and are ...

As giant slabs of Earth's crust collide in ultraslow motion, they create mountains, trigger earthquakes and forge new rocks. No one knows how or when this fundamental process, called plate tectonics, ...

The West Coast of North America is a geologically tumultuous zone where tectonic plates collide, subducting under and ...

Researchers have detected a previously unknown layer of partially molten rock beneath Earth's crust. The discovery could help scientists learn more about the movements of Earth's tectonic plates, ...
