The planet won’t look like this forever. A future supercontinent could unleash brutal cold, rising heat, and even a wave of ...

The mechanisms underlying two important phenomena in the Archean—the emergence of continental crust and the presence of an exceptionally strong geomagnetic field—remain poorly understood. Notably, ...

Tiny zircon crystals are revealing that Earth’s earliest history may have included surprisingly complex tectonic activity.

Geoscientists say Earth will be home to one massive supercontinent about 200 million years from now; there are four prominent versions of this mega-continent. The climate might be surprisingly balmy ...

Earth’s oxygen-rich atmosphere, the very thing that allows complex life to exist, may not last forever. Coupled biogeochemistry and climate simulations estimate that the planet’s breathable air could ...

Our planet was once a harsh, alien, icy world. Yet this deep freeze may have shaped you, me and all life on Earth ...

We are fortunate to have an amazingly diverse collection of rocks waiting to be recognized and appreciated. Each beach rock ...

New research shows that a fragile clay layer beneath the Japan Trench played a key role in the extreme seafloor movement ...

Geologists from St. Petersburg State University, as part of an international scientific team, have analyzed rock data from ...

Gravity feels reliable—stable and consistent enough to count on. But reality is far stranger than our intuition. In truth, the strength of gravity varies over Earth's surface. And it is weakest ...

Beneath the rolling surface of the North Atlantic, the seafloor drops into a chasm so vast it rivals, and may even exceed, the Grand Canyon in scale. Known as King’s Trough, this hidden scar has long ...

Tectonics is the study of the structural geology of the Earth and other planetary bodies, and the local and regional processes that created that rock geometry. This includes the movements of the Earth ...
