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 ...

A section of Earth’s mantle beneath Oman appears to be unusually warm, in what researchers say may be the first known “ghost plume” – a column of hot rock emanating from the lower mantle without ...

Some 4.6 billion years ago, Earth was nothing like the gentle blue planet we know today. Frequent and violent celestial impacts churned its surface and interior into a seething ocean of magma—an ...

Earth's deep interior still shapes the world above your feet. Water trapped far below the surface helps control how rocks move, melt, and recycle through the mantle. Some of that water carries a ...

An ancient slab of Earth's crust buried deep beneath the Midwest is sucking huge swatches of present-day's North American crust down into the mantle, researchers say. The slab's pull has created giant ...

When the supercontinent Pangea began to fragment around 200 million years ago during the Early Jurassic, it reshaped the face of the planet. Vast new oceans opened, continents drifted apart and the ...

A subtle change in iron ions’ electronic configuration produces a measurable difference in seismic wave speeds through mantle ...

Forbes contributors publish independent expert analyses and insights. David Bressan is a geologist who covers curiosities about Earth. An international team of researchers investigated how Earth’s ...

Far below the oceans and continents we know, Earth’s deep mantle appears to have stored far more water in its early history than scientists once imagined. New experimental work on high‑pressure ...

Millions of years ago, a fiery plume rising from Earth’s mantle reshaped continents, closing ancient seas and lifting land that would forever change life on our planet. This upheaval forged a bridge ...
