Surprising differences in the two so-called Large Low-Velocity Provinces may risk instability in Earth's protective magnetic field.

This crustal material was then stirred through the mantle over millions of years and accumulated to form the LLVPs. Schematic diagram showing the ... is extracted from the Earth’s core. This impacts ...

It’s not much of a stretch to say that Earth’s inner structure, especially the innermost spherical core, has stupefied scientists for generations. It sits over 3,000 miles below the surface, smaller ...

Buried more than 3,000 miles beneath our feet, Earth’s solid inner core was once thought to be unchanging—locked in place at ...

and their positioning in the deep mantle on each side of the planet, means that they affect how heat is extracted from the Earth's core. This impacts convection in the outer core—a process that ...

Scientists have confirmed that the Moon has a solid inner core with a density similar to iron. The core's structure mirrors that of Earth's, with a fluid outer ... a global mantle overturn ...

Our planet’s core is made mostly of iron, but it might also contain primordial helium that formed just after the Big Bang. Helium normally has trouble bonding with other elements, but ...
