A new study of decades worth of seismogram data shows that the surface of Earth’s iron and nickel core is more malleable than ...

Earth cross section showing the classic distinction between crust, mantle and core. But new research ... [+] shows Earth's structure is far more complicated and may change over time. Analyzing an ...

The two giant blobs — one beneath the Pacific Ocean and one beneath Africa — lie at the boundary between Earth's mantle and its outer core, some 1,900 miles (3,000 kilometers) beneath the surface.

Earth’s core is located below the middle layer called the mantle and the outer layer–or crust. It consists of two main parts–a liquid outer core and a more solid inner core. The outer layer ...

Water-bearing subducted slabs may not dehydrate and contribute to chemical heterogeneities at the core–mantle boundary, according to high-pressure and high-temperature melting experiments.

At the time, scientists weren’t sure if these formations near the boundary between Earth’s mantle and core were a temporary phenomenon, or if they had existed there for millions or billions of ...

Discovered at the boundary between Earth’s mantle and core, these so-called “Large Low-Shear-Velocity Provinces” (LLSVPs) stretch a staggering 620 miles high — dwarfing Everest’s summit ...

Seismic waves are the best tool scientists have to peer inside a planet, especially since we can’t drill into the Martian mantle or core. When a quake or impact occurs, it generates P-waves ...
