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 ...

New study reveals that Earth's inner core is undergoing unexpected structural changes, challenging long-held assumptions ...

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 ...

A new study out this week said that the Earth's inner core is less solid than previously thought. Scientists still have ...

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

Scientists of course cannot cut into Earth and directly observe its insides. Instead, their knowledge is inferred from the ...

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

First, a few basics. The Earth’s inner core, which is smaller than the moon, is solid iron and nickel. It’s surrounded by a layer of molten metal known as the outer core, followed by the Earth’s ...

Our planet's interior is much too deep and hot to explore ... Seismic waves are shock waves that propagate through Earth's layers after an earthquake or explosive event, traveling at different ...

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 ...
