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.

They found an odd ring around the outer core's equator, where earthquake waves move more slowly than in surrounding regions. Earth's outer core is made up of liquid iron and nickel and surrounds ...

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

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

Then there is the outer core, made of liquid metal, and the inner core, a solid ball of metal. At least, that is what scientists thought. New research published in the journal Nature Geoscience ...

Scientists confirm the Moon has a solid iron core, like Earth’s, with a molten outer layer. This discovery reshapes our ...

Seismic waves suggest the planet's solid inner core is being pulled out of shape – and it has undergone these changes over just a few decades ...

Scientists found that the inner core’s structure changes as it rotates. It deforms at its border, potentially accumulating more material in some areas and less in others — almost like creating hills ...

"The transition from the innermost (solid) ball to the outer shell of the inner core (also solid shell) seems rather gradational than sharp," explains study coauthor Dr. Thanh-Son Phạm.

Tectonic plates float on the semi-solid mantle, which moves very slowly as a result of convection currents driven by heat energy from the hot core. The outer core is liquid iron and nickel and ...

Its temperatures can reach 5500°C. 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 ...

In the Earth (see image below right), the liquid metal that makes up the outer core passes through a magnetic field, which causes an electric current to flow within the liquid metal. The electric ...
