Earth's surface environment hosts large reservoirs of hydrogen (H, mainly in the form of water, H 2 O), nitrogen (in atmospheric N 2) and carbon (mainly in carbonate rocks). H, N and C are sometimes ...

South African diamonds have revealed nickel-rich metallic inclusions, offering the first direct evidence of reactions predicted to occur deep in Earth’s mantle. The study shows how oxidized melts ...

Food production is already one of the biggest stressors to our planet, but it’s made substantially more challenging by the interaction of Earth system processes, according to new research. Earth ...

Scientists have traced the origins of complex life to the breakup of the supercontinent Nuna 1.5 billion years ago. This tectonic shift reduced volcanic carbon emissions, expanded shallow seas, and ...

Our Earth is around 4.5 billion years old. Way back in its earliest years, vast oceans dominated. There were frequent volcanic eruptions and, because there was no free oxygen in the atmosphere, there ...

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 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 ...

A geoscientist is someone who studies the Earth’s physical makeup and history. Geology is the science that provides the key to finding new sources of useful Earth materials and to understanding Earth ...

COLLEGE PARK, Md. — A University of Maryland-led team of scientists has discovered that diamonds can be natural time capsules, preserving information about the cycling of sulfur between Earth’s crust, ...

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.
