Scientists discovered plate anomalies in Earth's mantle using seismic wave analysis. These mysterious structures challenge tectonic theories.

About 56 million years ago, Europe and North America began pulling apart to form what became the ever-expanding North Atlantic Ocean. Vast amounts of molten rock from Earth's mantle reached the ocean ...

The record-breaking mission offers an unprecedented opportunity to study the geology of our planet’s largest layer.

A study using EBSD and TEM imaging found that “b” dislocations in olivine occur in roughly 17% of analyzed crystals. These defects, once considered minor, may significantly influence mantle ...

Earth's inner core, once rotating faster than the surface, has begun to slow, impacting day length by fractions of a second. This subtle shift, detected through seismic wave analysis, reveals complex ...

After accounting for Earth’s rotation, gravity is slightly weaker beneath Antarctica than anywhere else on the planet. That ...

Far below your feet, nearly 1,800 miles beneath oceans and continents, Earth carries two massive scars from its violent youth. They are so large they rival continents in size, yet no human will ever ...

All the activity on Earth’s surface — erupting volcanoes, shifting tectonic plates, restless seas and myriad forms of life — depends on the two-part engine under the hood. Directly beneath Earth’s ...

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

A new model suggests “mantle rain” ensures we will always have a surface ocean Theo Nicitopoulos, Hakai The Earth’s oceans have risen and fallen over the millennia. But they have, on average, been ...

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

Precious metals may be escaping from the planet’s core. This hotly debated subject could help us understand Earth’s evolution and determine whether life exists elsewhere in the Universe ...
