Like a mosquito tunneling into the skin to get at the rich feast within, geologists poked a long, narrow drill into Earth's crust last year, pulling out a treasury of geological goodness. The result ...

Deep beneath our feet, far below the crust and mantle, Earth’s metallic heart is not as sealed off as geologists once assumed. New research indicates that gold and other precious metals are slowly ...

Our planet's core is rich in gold that can leak out into the mantle, and in some cases, end up in volcanos on the surface, according to a new study. When you purchase through links on our site, we may ...

Extreme chemical reactions could explain why Earth's middle layer has so much carbon. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. The ...

Earth's internal structure consists of four layers: the crust, mantle, outer core (liquid iron), and inner core (solid iron), with temperatures increasing significantly with depth, reaching values ...

Discover what the most abundant element on Earth is. Learn why iron dominates the planet, which elements rule the crust and ...

Oceanic island hotspots — Hawaii and Iceland — are the final destinations of elemental isotopes from the beginnings of Earth, in concentrations found nowhere else on Earth’s crust. Until now, it was ...

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 ...

Mysteries still abound for scientists studying the Earth’s climate, biosphere, surface topography, and even the oceans, but they all have a distinct advantage: the subjects of their inquiries are, to ...
