Scientists have ended a 9-year-old debate by proving that Earth's core rotates faster than its surface, by about 0.3 to 0.5 degree per year. Earth’s iron core consists of a solid inner core about ...

Our planet may have had a recent change of heart. Earth’s inner core may have temporarily stopped rotating relative to the mantle and surface, researchers report in the January 23 Nature Geoscience.

A river of molten iron, more than 2,000 kilometers below the surface, appears to have pulled off something Earth scientists ...

We’ve learned a lot about our planet’s interior simply by tracking how the seismic energy released by earthquakes moves through or reflects off the different layers present beneath Earth’s surface.

Our planet's core is 2.5 years younger than the crust, a new study found. Researchers calculated the crust's relative ages and compared it with the core's age estimates. Apart from shedding new light ...

What’s the News: In geologists’ traditional view of the middle of the Earth, the solid inner core is gradually growing as more of the liquid core freezes, as the planet continues its billions-of-years ...

The Earth’s inner core is rotating faster than the outer mantle and crust, according to a new study of earthquake data. The difference is slight but means that the solid inner core makes an extra ...

The giant iron ball at the center of the Earth appears to be spinning a bit faster than the rest of the planet. The solid core that measures about 1,500 miles in diameter is spinning about one-quarter ...
