Earth’s core is located below the middle layer called the mantle and the outer layer –or crust. It consists of two main parts ...

The Earth's interior is composed of four layers, three solid and one liquid—not magma but molten metal, nearly as hot as the surface of the sun. The deepest layer is a solid iron ball ...

Located 3,000 miles below the Earth’s surface, the inner core is anchored by gravity within the molten liquid outer core.

Researchers found evidence that the Earth's inner core is changing shape, suggesting unseen processes affecting its movement ...

Earth's interior is made up of a series of layers that sit below the surface crust. In order of depth, these layers include the solid, but flowing mantle, the liquid outer core and the solid iron ...

The Earth's internal layers including the mantle, outer core and inner core. New research shows the inner core undergoes structural transformation likely caused by outer core disturbance.

The surface of the Earth's inner core may be changing, as shown by a new study by USC scientists that detected structural ...

The study analyzed decades of seismic data, including recordings of repeating earthquakes near Antarctica between 1991 and ...

Our planet's interior is much too deep and hot to explore with probes, so scientists rely on seismic waves to understand and model its structure. Seismic waves are shock waves tha ...

6. Show students how to cut their eggs. 7. Ask students to name the different layers of the Earth's interior using the egg as a model that represents the Earth. Caution: The egg analogy has some ...

Research on hidden structures deep within Earth’s mantle challenges theories about our planet’s middle layer and could ...
