The solid metal core of Earth does not rotate perfectly in time with the outer layers of the planet, and new research ...

The inner core of the Earth appears to hold an innermost secret. Geology textbooks almost inevitably include a cutaway diagram of the Earth showing four neatly delineated layers: a thin outer ...

A new region of Earth's core could help scientists understand our magnetic field—the shield that protects life on the surface. ... A diagram showing seismic waves traveling through Earth.

A diagram explains how the Earth's core can act as a giant dynamo, creating our planet's magnetic fields. NASA/Andrew Z. Colvin, CC BY-SA 4.0 ...

The inner core is made of solid iron-nickel about 3,000 miles below the surface of the Earth. Scientists believe that the inner core’s rotation began to slow down in 2010 , but what that really ...

A ‘ghost plume’ identified deep in the mantle beneath Oman suggests there may be more heat flowing out of Earth’s core than ...

Scientists believe that Earth’s core is a massive ball of iron.However, a new discovery suggests that the Earth’s core is surrounded by an unexpected ancient structure. A high-resolution map ...

Earth's inner core is undergoing structural transformation. Located 3,000 miles below the Earth's surface, the inner core is anchored by gravity within the molten liquid outer core. Until now the ...

A collaborative research group has succeeded, for the first time, in measuring the speed of sound of pure iron under pressures similar to the Earth's inner core boundary.

Earth's core is the hottest part of the planet, equivalent to that of the Sun's surface. The core is buried around 5,180 kilometres deep inside the Earth and consists mainly of iron and nickel.

A study published in June 2022 examined seismic data from nuclear bomb tests to closely track how the inner core rotation changed from 1969 to 1974. Their results show that the core was ...
