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

inner core rotation is thought to help power Earth’s magnetic field, though more research is required to unravel its precise ...

The rotation of Earth's inner core really has slowed down, a new study has confirmed, opening up questions about what's ...

Currently, the rotation between the inner and outer cores is becoming less distinct. When researchers say “reverse,” they mean the inner core is rotating slightly slower than the outer core, Brown ...

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, ...

A single rotation of our planet takes 24 hours ... which matches observations by astronomers and satellites. Earth’s inner core has been slowing down for 14 years. It comes just weeks after ...

Located over 4,500 kilometres beneath the surface and roughly the size of the moon, the inner core’s behaviour is studied through seismic waves from earthquakes and nuclear tests. The USC ...

While Earth's slowdown is not noticeable on human timescales, it's enough to work significant changes over eons. One of those changes is perhaps the most significant of all, at least to us: ...

The rotation of the planet ... a fluctuation of 2 to 3 milliseconds has been linked to large-scale flows in Earth's fluid core. But there's another fluctuation of about 3 to 4 milliseconds ...

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 ...

Now, a team of geophysicists from ETH Zürich in Switzerland thinks they have found the answer in Earth's molten iron core, with tiny alterations affecting the planet's rotation. There are several ...

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 ...
