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 ...

Deep below Earth's surface lie two gigantic structures with mysterious origins. Now, seismologists have found new clues about their composition that could upend our understanding of the whole planet's ...

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 ...

Seismic waves traveling through Earth's interior often propagate at different speeds depending on their direction, a ...

For decades, scientists have been baffled by two enormous, enigmatic structures buried deep inside Earth with features so vast and unusual that they defy conventional models of planetary evolution.

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 ...

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 ...

If this continues to develop, this rift could grow into a new tectonic plate boundary—splitting the African continent in half ...

Earthquakes that jiggle Earth's middle layer may be more widespread than scientists thought. A new map of these mysterious deep earthquakes shows that they occur all around the world and that they may ...

New research suggests that dark energy isn't needed to explain the acceleration in the expansion of the universe — instead suggesting giant voids in space are creating an illusion. When you purchase ...

A recent study has revealed an unexpected shift that happened beneath the Pacific Ocean ...

Seismic mapping of North America has revealed that an ancient slab of crust buried beneath the Midwest is causing the crust above it to "drip" and suck down rocks from across the continent. When you ...
