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

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 ...

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

Parts of 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–Madison has ...

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 ...

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 ...

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 years, scientists believed that changes in the Earth's interior, such as volcanic eruptions and tectonic plate collisions, primarily affected the surface environment. Events such as the mass ...
