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 ...

Scientists tracking Earth's magnetic pole have recently spotted it heading toward Siberia. Where it will end up, no one knows ...

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

The researchers used seismic data to study the Moon's interior composition. They mapped the lunar interior in detail by studying how acoustic waves, produced by quakes, interact with the material ...

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 ...

This process of freezing releases elements, such as oxygen and carbon, which aren't compatible with being in a hot solid. It creates a hot, buoyant liquid at the bottom of the outer core. The liquid ...

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 ...

It helps to visualize this: Earth’s inner core is a solid ball that is surrounded by a fluid outer core. This is how it can rotate at a different pace compared to the planet’s outer layers ...

A new mysterious donut-shaped region has been discovered in Earth's core by scientists at the Australian National University.
