Is Earth's inner core solid or liquid? While the inner core is extremely hot, experts have known that it is solid for many ...

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 ...

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 ...

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 ...

The rotation of the Earth's inner core may be reversing, scientists have found in a study that sheds new light on geological processes occurring deep within our planet.

An analysis of Hawaii’s volcanic rocks revealed Earth’s core is leaking gold and other precious metals, a study found. The elements emerge when ocean islands form.

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) .

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 ...

More than 99.999 per cent of Earth’s stores of gold lie buried under 2,900km (1,800 miles) of solid rock, locked away within the Earth’s metallic core and far beyond the reaches of humankind.

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.
