Dig to Earth's CORE! is a Roblox experience that answers the age-old question almost every person has asked themselves: What ...

As the Earth gradually cools, the inner core expands outwards at the surrounding iron-rich liquid "freezes." That said, it is still extremely hot, at least 5,000 Kelvin (K) (4,726.85°C) .

NPR's Ayesha Rascoe talks to John Vidale, professor of earth sciences at the University of Southern California, about new research suggesting the rotation of Earth's inner core may be slowing down.

The rotation of Earth’s inner core may have paused and it could even go into reverse, new research suggests.. The Earth is formed of the crust, the mantle and the inner and outer cores. The ...

The new research from the University of Southern California, now published in Nature, noticed that the Earth’s inner core was moving slower than the surface, termed “backtracking,” and has ...

A billion years may not sound young, but researchers estimating the age of the Earth’s core say it could be between 1 and 1.3 billion years old – which is at the lower end of previous estimates.

The Earth’s inner core is separated from the rest of the planet by its liquid outer core, so it rotates at a different pace and direction.

The latest discoveries about the inner core have fueled vigorous disagreements among the world’s top Earth scientists and given rise to competing theories of varying credibility, Vidale says ...

Because the Earth’s core is so deep, and hidden within a molten layer of rock, it’s pretty much impossible to dig down and simply discovery it for ourselves.

In the mid-1990s scientists found evidence that Earth’s inner core, a superheated ball of iron slightly smaller than the moon, was spinning at its own pace, just a bit faster than the rest of ...

Earth's core has been a growing topic of interest. It is responsible for the planet's magnetic field, which protects life from the sun's radiation. Despite its importance, ...
