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 core’s rotation matched Earth’s spin. Then it slowed even more, until the core was moving backward relative to the fluid ...

The Chinese scientists propose that this internal layer is the solid part of Earth's core, tilting by a modest 0.17 degrees relative to the outer layers. This groundbreaking conclusion contradicts ...

Our study of the Earth’s core has advanced quite a bit, especially in recent years, with scientists discovering a hidden layer of molten rock beneath the Earth’s crust. Further, the way that ...

Giant regions of the mantle where seismic waves slow down may have formed from subducted ocean crust, a new study finds.

Researchers had long suspected the Earth had another layer at its core, but because its composition is so similar to the layer surrounding it, the innermost inner core was hard to spot.

Earth appears to be a chill blue planet, but deep down, it’s really a metalhead. Its outer core is mostly molten iron (and ...

The outer core is liquid iron and nickel and generates ... The mantle is the thickest layer of the Earth and is made of semi-solid rock that moves very slowly, like a liquid.

The new study postulates that the core's iron atoms migrate into new ... of our planet and its dancing atoms, the Earth's evolving layers have yet to be pulled back fully. Chase joined Mashable's ...

The discovery that inert helium can form bonds with iron may reshape our understanding of Earth’s history. Researchers from ...

A groundbreaking study reveals that the Moon has a solid inner core with a density comparable to iron, reshaping our understanding of its history and evolution within the Solar System.
