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

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 ...

The work was done by Haruki Takezawa and Kei Hirose at the University of Tokyo and colleagues, who suggest that Earth’s core could host a vast reservoir of primordial helium-3 – reshaping our ...

Scientists know heat flows from Earth’s interior into space at a rate of about 44 × 10 12 W (TW). What they do not know, however, is how much of the heat is primordial. Source: Doyeon Kim ...

Earth`s interior provides heat from radioactive decay and chemical compounds by volcanic degassing, such as sulfur dioxide (SO 2) and carbon dioxide (CO 2). Quasiperiodic changes in Earth's orbit ...

Seismologists have long understood that seismic waves from earthquakes travel at different speeds through various parts of Earth’s interior. By analyzing these variations, scientists can map the ...

The rate of both depression and the subsequent rising motion tells something about Earth's interior, particularly the mantle. Think of pushing down on a sponge and then watching as it expands when ...

These are critical raw materials; critical both because we need them in almost every gadget and technology, but also because the supply chain is so precarious ...
