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 ...

Add Yahoo as a preferred source to see more of our stories on Google. Like a mosquito tunneling into the skin to get at the rich feast within, geologists poked a long, narrow drill into Earth's crust ...

A new analysis of rocks thought to be at least 2.5 billion years old helps clarify the chemical history of Earth's mantle -- the geologic layer beneath the planet's crust. The findings hone scientists ...

Active lava flows spilling out of the Erta Ale volcano in Afar, Ethiopia. (Derek Keir/University of Southampton/University of Florence) (CN) — Millions of years ...

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 ...

Just when things couldn't get any crazier in the US, scientists have discovered that the underside of the Earth's crust is dripping molten lava inside the planet. The hot lava is thought to be ...

What is the chemical composition of the Earth’s interior? Because it is impossible to drill more than about ten kilometres deep into the Earth, volcanic rocks formed by melting Earth’s deep interior ...

Beneath California's Sierra Nevada mountains, the crust is peeling away. This process, called lithospheric foundering, is nothing to worry about. In fact, it may be how the continents first formed.

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 ...

The Earth is made of different layers: the core, mantle and crust. Plate tectonic theory shows that the crust of the Earth is split into plates (pieces of the Earth’s crust). The movement of these ...

The mineral olivine contains melt inclusions (black dots), just a few micrometers in size. The geochemists isolated these inclusions and investigated the isotopic composition with mass spectrometers.
