Earth's solid inner core has begun to slow its rotation relative to the surface, a shift detected through seismic data. This ...

Measurements of seismic waves over many years suggest the Earth's core is deformed and reshaped by conditions of extreme heat ...

Earth’s inner core has long puzzled scientists because seismic waves move through it unevenly. Compressional waves from earthquakes travel about 3 to 4 percent faster along the planet’s rotation axis ...

Earth’s inner core has long challenged researchers because seismic waves do not move through it uniformly. Compressional waves generated by earthquakes travel roughly 3 to 4 percent faster along Earth ...

These chemical oddities may explain why Earth seems to be deficient in certain elements — and could prove useful in catalysts ...

Cartoon of the Earth with cutaway showing the mantle and inner and outer core. Magnetic field lines produced by the geodynamo extend into space and interact with the solar wind. The iron-rich core at ...

The blobs lie at the base of Earth’s mantle, around 1,802 miles beneath Africa and the Pacific.

PCWorld reports that scientists discovered Earth’s inner core has slowed its rotation relative to the crust, even appearing to stop moving in a phenomenon that occurs every 35 years. This iron-nickel ...

The Earth’s inner core, a solid sphere predominantly composed of iron and nickel, occupies a central role in our planet’s evolution and geodynamo processes. Although hidden beneath thousands of ...

What is the speed and timing of the Earth’s inner core cooling? This is what a recent study published in Nature Communications hopes to address as a team of scientists investigated the composition ...
