Key Takeaways on Earth's Inner Core Earth's inner core is solid and blistering hot. For decades, scientists have known ...

Earth is made up of several layers: the lithosphere, asthenosphere, lower mantle (also known as mesospheric mantle), outer core and inner core.

Earth's inner layers have just got a bit more complicated, with scientists discovering a whole new inner core within the center of the planet. Research released on February 21 in the journal ...

One of geology’s basic principles is that the Earth is made up of four layers: the crust, the mantle, the outer core, and the inner core. But this may be squashed in light of a new study that ...

They found that the inner core was rotating in the same easterly direction as the Earth itself, albeit slightly faster than the other solid layers—the mantle and surface.

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 rotation of Earth’s inner core may have paused and it could even go into reverse, new research suggests.

A new study suggests Earth's inner core may have paused and reversed direction, shedding further light on how different layers of the Earth interact.

Earth’s core is pretty dynamic. Its spin speeds up and slows down based on how its two primary layers are behaving. As we improve the waveform techniques used to study the deepest layer ...

Two Australian scientists argue in a new paper that within the Earth’s core, based on measurements of waves reverberating along the Earth’s diameter, is an innermost inner core, about 800 ...
