Water gushes through dark, craggy rocks on the shore. A massive water reservoir is hidden deep beneath the ocean floor off the coast of New Zealand — and it may explain why the region experiences slow ...

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

New research shows that some frozen moons may hide boiling oceans beneath their icy shells, shaping strange surface features.

Like a moth in a cocoon, the metamorphosis of Earth's crust from molten goop to solid land is hidden from view, leaving scientists to guess at how the eons-long process unfolds. Using nearly four ...

The liquid outer core is surrounded by the thick layer called the mantle. It’s mostly solid rock, not melted like lava. Over time, changes in heat and pressure make the solid rock slowly flow. It’s ...

A first thought when describing a rock formation likely isn't a mille-feuille, but there are actually certain types composed of many thin layers that bring the flaky pastry to mind. Not only that—but ...

Stanford researchers have created the first-ever global map of a rare earthquake type that occurs not in Earth’s crust but in our planet’s mantle, the layer sandwiched between the thin crust and Earth ...

A layer of rock just 520 million years old sat directly on top of ancient rock dating back 1.4 to 1.8 billion years.

Scientists at Stanford have unveiled the first-ever global map of rare earthquakes that rumble deep within Earth’s mantle rather than its crust. Long debated and notoriously difficult to confirm, ...

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 ...
