Tectonic plates — which divide Earth’s crust and reshape our planet in an ongoing, dynamic process — may be the key to supporting life. In fact, because Earth is the only planet known to be home to ...

Researchers used small zircon crystals to unlock information about magmas and plate tectonic activity in early Earth. The research provides chemical evidence that plate tectonics was most likely ...

Our planet is in constant flux. Tectonic plates—the large slabs of rock that divide Earth’s crust so that it looks like a cracked eggshell—jostle about in fits and starts that continuously reshape our ...

Researchers have studied structures in the lunar maria that indicate earthquakes. These could also affect manned missions.

Far beneath the ocean's surface, where mountain belts rise and ancient oceanic crust lies hidden, a long-lost tectonic plate has been brought back into view. In one of Earth's most tectonically ...
