University of Wyoming geology Professor and National Geographic Explorer Ken Sims has published a new book on the application of isotopes to understanding earth system processes. “Isotopic Constraints ...

Sophisticated analysis of tiny bubbles of ancient gas trapped in volcanic rocks, combined with new geophysical modeling, has cast new light on long-held assumptions about the deep Earth. An ...

The Mid-Atlantic Ridge in Iceland. This area is the boundary between the North American and Eurasian tectonic plates, which move apart ~ 2.5 cm/year. Subduction and the formation of continents, a ...

Scientists at Yale and in Singapore have devised what may be the ultimate acid test — a comprehensive model for estimating the origins of Earth’s habitability, based in part on ocean acidity. The new ...

For over half a billion years, Earth’s magnetic field has risen and fallen in sync with oxygen levels in the atmosphere, and scientists are finally uncovering why. A NASA-led study reveals a striking ...

When we look at the solid ground beneath our feet, it's easy to assume Earth has always been this way. But our planet tells a story so extraordinary, so ...

Geomorphology – the study of landforms and the processes that shape the Earth’s surface – integrates observations of tectonic, fluvial, glacial, aeolian, and coastal dynamics to explain landscape ...

Our planet plunged into one of the most dramatic climate states in its long history, approximately 720–635 million years ago.

MADISON — Parts of the ancient Earth may have formed continents and recycled crust through subduction far earlier than previously thought. New research led by scientists at the University of Wisconsin ...

Venus is often called Earth’s twin, but the two planets evolved into dramatically different worlds. Scientists believe the explanation may lie in the planet’s geology and the absence of key geographic ...
