Buried more than 3,000 miles beneath our feet, Earth’s solid inner core was once thought to be unchanging—locked in place at the heart of the planet. But new research has revealed something much more ...

The Earth's inner core was once liquid, but has turned solid over time. As the Earth gradually cools, the inner core expands outwards at the surrounding iron-rich liquid "freezes." That said, it ...

We all grew up learning that we live on the Earth’s crust, which is just a thin layer above the mantle. Beneath that, the outer core surrounds the inner core, and… well, that’s it ...

First ever supercomputer simulations of Mars with a fully molten core could explain the Red Planet's unusual magnetic field. Billions of years ago, Mars had an active magnetic field. Mysteriously, its ...

The Earth's internal layers including the mantle, outer core and inner core. New research shows the inner core undergoes structural transformation likely caused by outer core disturbance.

The next layer is the mantle, which makes up most of Earth's volume and is composed of dense, semi-solid rock. Then there is the outer core, made of liquid metal, and the inner core, a solid ball ...

The Earth's interior is composed of four layers ... in diameter. Although this inner core is white hot, the pressure is so high the iron cannot melt. The iron isn't pure—scientists believe ...

According to a recent study, the Earth's inner core, that is a solid ball of iron and nickel, is slowing down in relation to the planet's surface. The same was confirmed by USC scientists ...

USC researchers identified a six-year cycle of super- and sub-rotation in the Earth's inner core, contradicting previously accepted models that suggested it consistently rotates at a faster rate ...

New research suggests that Earth's inner core, long believed to be stable, may be undergoing structural changes, including a possible shift in shape, shedding light on the mysteries beneath the ...

It’s long been thought that tectonic plates needed to dive beneath each other to create the chemical fingerprint we see in ...

For example: What are the four main layers of the earth? They would be the inner core, the outer core, mantle and crust. What about this one: What percentage of the Earth’s surface is covered in ...
