Deep within Earth’s mantle lie two enormous regions, often referred to as "islands," which are the size of continents.

The Earth's magnetic field and oxygen evolved together over 540 million years, according to a major NASA study.

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 ...

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 ...

New research has dramatically reshaped our understanding of Earth’s early geological history, overturning traditional beliefs about how the planet’s first continents came into being. Researchers from ...

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 ...

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 ...

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 ...

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 ...
