A study published in Earth and Planetary Science Letters challenges a widely held assumption about the thermal state of Earth ...

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

Long-lost remnants of tectonic plates have been discovered sunken deep inside the Earth's mantle. These plate remains were found lurking underneath the center of other continental plates, far from ...

The Earth’s oceans have risen and fallen over the millennia. But they have, on average, been relatively stable over billions of years. The balance of the deep water cycle—the exchange of water between ...

Several studies have predicted that not all geomagnetic reversals have been discovered, but it was unknown in which periods they might be hidden. Researchers led by the National Institute of Polar ...

A study published in the journal Nature Geoscience has revealed a subtle yet significant phenomenon beneath the North American continent; its ancient bedrock is slowly dripping into the Earth’s mantle ...

Lavas from hotspots—whether erupting in Hawaii, Samoa or Iceland—likely originate from a worldwide, uniform reservoir in Earth’s mantle, according to an evaluation of volcanic hotspots published today ...

Unsustainable irrigation and drought have emptied nearly all of the Aral Sea’s water since the 1960s, causing changes extending all the way down to Earth’s upper mantle, the layer beneath the planet’s ...
