Deep beneath our feet, far below the crust and mantle, Earth’s metallic heart is not as sealed off as geologists once assumed ...

Earth's inner core may be layered like an onion, with silicon and carbon creating distinct zones that explain seismic wave ...

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 ...

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 ...

Scientists announced Monday that Earth is rotating slightly faster than normal, resulting in what is expected to become the second-shortest day ever recorded since precise atomic timekeeping began.

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 ...

Using observational and model-based data spanning the entire 20th century, scientists have for the first time have identified three broadly-categorized processes responsible for Earth's spin axis ...

Occasionally, planet Earth will grab the headlines: Underwater volcanic eruptions send ash into the air, or earthquakes generate massive waves that send people running for safety as the rest of us ...

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 ...

The Earth's spin isn't as consistent as it may seem. In fact, it naturally drifts and wobbles on its axis over time, and that's generally chalked up to the way mass is distributed and redistributed ...
