A new study of decades worth of seismogram data shows that the surface of Earth’s iron and nickel core is more malleable than scientists thought.

A groundbreaking study reveals that the Moon has a solid inner core with a density comparable to iron, reshaping our ...

Continent-sized structures of mineral protruding from the lower mantle towards Earth's outer core may be contributing to an ...

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 ...

Underneath the Earth’s crust we know there is a hot mantle and an even hotter outer and inner core, but now experts say we may have missed something all along. Recently scientists were able to ...

A major scientific breakthrough has settled a decades-old debate about the moon’s interior. Researchers have confirmed that ...

Well, the verdict is in. The Moon is not made of green cheese after all.

Outer core The outer core is the layer surrounding the inner core. It is made of liquid iron. Mantle The mantle is the layer of the Earth which makes up 84% of its volume. It is also the thickest ...

This inner core is surrounded by a liquid outer shell of the same composition, enclosed by the mantle—a thick layer that begins about 30 kilometers beneath the Earth's surface and extends to a ...
