Deep inside the mantle of Earth, Stanford scientists have recorded quakes which are physically not explainable.

Precious metals may be escaping from the planet’s core. This hotly debated subject could help us understand Earth’s evolution and determine whether life exists elsewhere in the Universe ...

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 ...

Researchers have drilled a window into the layer of our Earth that is responsible for volcanic activity, crust formation, and earthquakes. The mantle is incredibly difficult to study because it’s so ...

Graphic representation of Earth’s shell structure showing the super-heated metallic inner core in the centre, followed by the solid outer core, the rocky mantle and the thin crust towards the surface.

To understand the mantle—the largest layer of Earth’s rocky body—scientists drill deep cores out of the Earth. Scientists drilled the deepest core yet and recovered serpentinized peridotite that forms ...

Seismic waves created by earthquakes as they travel through the planet’s interior change speed and direction as they move through different materials. Things like rock type, density, and temperature ...

Back in my day, there were only four layers of Earth: the crust, mantle, liquid outer core and solid inner core. Now, scientists have revealed a new, distinct layer within our planet’s inner core, ...

A 2021 eruption in Iceland gave researchers rare and illuminating access to the mantle, one of the Earth’s layers. Ed Marshall, a geochemist at the University of Iceland, donning protective gear, ...
