Is Earth's inner core solid or liquid? While the inner core is extremely hot, experts have known that it is solid for many ...

The structure of Earth's core was first described in 1936, and for a long time we thought it was made exclusively of metal-loving heavy elements, mainly iron.

Identifying the composition of Earth's core is key to understanding how our planet formed and the current behavior of its interior. While it has been known for many years that iron is the main ...

Earth's composition is more complicated than we think and is changing continuously every day. The inner part of the planet can be divided into three different layers: crust, mantle, and core ...

Earth's inner core is likely a weird composition of superheated elements making it both liquid and solid at the same time, a study has suggested.

According to Alfred Baron, head of the Materials Dynamics Laboratory, "Understanding the composition of the liquid within the earth's core is an important question, as it can give us clues about ...

The liquid outer core of Earth might be the largest reservoir of carbon on the planet. The percentage sounds small, somewhere between 0.3% and 3%, but once you take into account the size of the ...

To extrapolate to Earth’s inner core, Heinz and his colleagues recently studied alloys of iron and silicon at temperatures up to 2,100C and pressures exceeding 800,000 times atmospheric pressure ...

Ancient helium that became trapped in Earth’s core when our planet formed billions of years ago may be leaking from lava flows, according to researchers. CNN values your feedback 1.

Studying Earth's core is no mean feat as it lies about 4,000 miles (6,400 km) beneath our feet, far beyond the realms of direct measurements. Instead, scientists use compressional sound waves and ...
