Located 3,000 miles below the Earth’s surface, the inner core is anchored by gravity within the molten liquid outer core. It's believed to play an important role in maintaining the planet’s ...

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 ...

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.

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 ...

"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.

Earth’s innermost layer is a hot, solid ball of metal surrounded by a liquid metal outer core. For decades, planetary scientists suspected that the solid inner core deformed over time as it spun.

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 ...
