Tectonics in the tropics trigger Earth's ice ages, study finds

Over the last 540 million years, the Earth has weathered three major ice ages—periods during which global temperatures plummeted, producing extensive ice sheets and glaciers that have stretched beyond the polar caps.

Drilling deep for clues on earthquakes

Lingering motion sickness is one of the occupational hazards of working at sea off the coast of Japan for three weeks. Hiroki Sone can attest to that, having spent part of the fall 2018 semester on the deepest scientific ...

A wrench in Earth's engine

Researchers at CU Boulder report that they may have solved a geophysical mystery, pinning down the likely cause of a phenomenon that resembles a wrench in the engine of the planet.

Research bolsters possibility of plate tectonics on Europa

A Brown University study provides new evidence that the icy shell of Jupiter's moon Europa may have plate tectonics similar to those on Earth. The presence of plate tectonic activity could have important implications for ...

Clay mineral waters Earth's mantle from the inside

The first observation of a super-hydrated phase of the clay mineral kaolinite could improve our understanding of processes that lead to volcanism and affect earthquakes. In high-pressure and high-temperature X-ray measurements ...
