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 ...

Can a movement many feet below our feet quietly change the Earth’s rotation? Over 3,000 miles below the ground, the Earth’s inner solid core a ball of iron and nickel whose temperature is as hot as ...

While most of us take the ground beneath our feet for granted, written within its complex layers, like the pages of a book, is Earth's history. Our history. Research shows there are little-known ...

Earth's inner core, the solid iron-rich mass at the center of our planet, is slowly growing as the surrounding molten outer core cools and freezes. But this process has been a source of debate amongst ...

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 ...

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 ...

The solid inner core at the center of the Earth, surrounded by the outer core, mantle and crust. Here’s why: While it is well known that a material must be at or below its freezing temperature to be ...

Geophysicists from ETH Zurich and SUSTech, China, have demonstrated the dynamo effect of the Earth’s core in a model in which viscosity has no influence, as is the correct physical regime for the ...

Alfred Wilson-Spencer receives funding from the Natural Environment Research Council (NERC) grants NE/T000228/1 and NE/V010867/1. He works for the University of Leeds. The iron-rich core at the centre ...
