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 ...

Deep inside Earth, far below the crust and mantle we learn about in school, two colossal structures loom above the core like ...

Scientists found rocks deep inside Earth's mantle that generate hydrogen and could reveal clues about deep energy and the ...

Stephen has degrees in science (Physics major) and arts (English Literature and the History and Philosophy of Science), as well as a Graduate Diploma in Science Communication. Stephen has degrees in ...

The rotation of Earth's inner core may have paused and it could even go into reverse, new research suggests. The Earth is formed of the crust, the mantle and the inner and outer cores. The solid inner ...

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 ...

A new study confirms that Earth's inner core has been rotating more slowly than usual since 2010. This mysterious "backtracking" could also end up slightly altering the planet's overall rotation, ...

A new study adds evidence to the idea that Earth's inner core is slowing its spin, though still rotating in the same direction as the planet. KATERYNA KON / SCIENCE PHOTO LIBRARY via Getty Images The ...

Diamonds hitch a ride to Earth's surface inside a rare magma called kimberlite, but only if that magma stays buoyant.
