Scientists say they’ve confirmed Earth’s inner core has been slowing down. Here’s what it could mean — and why the topic has been the subject of fierce debate.

For geologists, this is fascinating stuff. The radius of the Earth is just shy of 4,000 miles and the deepest well anyone has ever dug is a little over 7.5 miles deep. The crust under the Earth ...

The inner core is made of solid iron-nickel about 3,000 miles below the surface of the Earth. Scientists believe that the inner core’s rotation began to slow down in 2010 , but what that really ...

In elementary school science class, we learned that the Earth has three main layers: the crust, mantle, and the core.In reality, the core—which is over 4,000 miles wide—has two layers: a ...

Around 1,800 miles beneath your feet lies a giant, blazing-hot ball of metal. It's the innermost part of our planet, Earth's core. It has a profound impact on your life, though none of us can even ...

The innermost inner core of the earth: Evidence for a change in anisotropic behavior at the radius of about 300 km. Proceedings of the National Academy of Sciences . Vol. 99, October 8, 2022 ...

Deep beneath our feet, at a staggering depth of over 5,100km, lies Earth's inner core—a solid ball of iron and nickel that plays a crucial role in shaping the conditions we experience on the ...

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) (4726.85°C) .

You might think the Earth's largest gold reserves are locked up at Fort Knox. But Earth's core is rich with the precious metal - and it's slowly making its way up towards us.

Deep beneath our feet, at a staggering depth of over 5,100km, lies Earth's inner core — a solid ball of iron and nickel that plays a crucial role in shaping the conditions we experience on the ...
