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 ...

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 ...

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 ...

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 ...

The Moon is not, in fact, a giant cosmic wheel of Gouda. In a landmark paper published in Nature, researchers from the French ...

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 ...

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 ...

A new geological model revolutionizes a century of theories: a rigid wedge of mantle keeps the Himalayas standing.

A growing weak spot in the magnetic field surrounding the Earth could lead to satellite malfunction and even cause them to ...

Breakthroughs, discoveries, and DIY tips sent every weekday. Terms of Service and Privacy Policy. In elementary school science class, we learned that the Earth has ...

The distance from the Earth's surface to its center is almost 4,000 miles—but our planet's structure is not uniform and is actually made up of several different layers, some of which are hotter than ...
