EarthEarth’s tectonic plates won’t slide forever
Earth’s surface morphs, owing to the movement of its tectonic plates. But those plates didn’t use to move so quickly. And in a few billion years they’ll grind to a halt, new research suggests.

EarthCarbon dioxide could explain how geysers spout
A new study overturns 150 years of thinking about Yellowstone’s geysers. Carbon dioxide, not just hot water, may be driving those spectacular eruptions.

ChemistryParticles in air help fatten clouds’ water droplets
Making their own clouds has shown scientists how the fattest water droplets form. Understanding this could lead to better forecasts of climate change.

EarthQuake risk in some central states rivals California’s
Risks of tremors in some central U.S. states are as high as those in quake-prone California. The reason: waste fluids from oil and gas drilling.
