From these indirect observations, scientists have calculated that the scorchingly hot inner core, with temperatures ...

A new chapter of the Earth's history may be about to be written after boffins discovered evidence there may be another layer ...

The Earth's inner core was once liquid, but has turned solid over time. As the Earth gradually cools, the inner core expands outwards at the surrounding iron-rich liquid "freezes." That said, it ...

This appears to be the case, to a rather stunning extent, in the instance of the reporting this week around new findings that researchers say shows the rotation of Earth’s inner core is slowing ...

WASHINGTON, D.C. — Earth’s inner core, a solid metal ball gyrating within the molten outer core, may be both slowing down and changing shape. Recent analyses of earthquake waves have suggested ...

The Earth's interior is composed of four layers ... in diameter. Although this inner core is white hot, the pressure is so high the iron cannot melt. The iron isn't pure—scientists believe ...

Earth’s inner core has been slowing down for 14 years. It comes just weeks after another team of researchers suggested that the slight increase in the length of a day may be because Earth’s ...

Because of the specific temperature and pressure conditions inside the Earth, the outer core is in a molten state, while the inner core remains solid." Electrically charged, liquid iron flows ...

Earth’s inner core, a solid metal ball gyrating within the molten outer core, may be both slowing down and changing shape. Recent analyses of earthquake waves have suggested that around 15 years ago, ...

Geophysicists studying seismic waves from earthquakes have found evidence suggesting that Earth's inner core not only rotates differently but also changes shape. Analysis of earthquake waveforms ...
