As the Earth gradually cools, the inner core expands outwards at the surrounding iron-rich liquid "freezes." That said, it is still extremely hot, at least 5,000 Kelvin (K) (4,726.85°C).
Scientists say they’ve confirmed Earth’s inner core has been slowing down. Here’s what it could mean — and why the topic has been the subject of fierce debate.
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 ...

The surface of Earth's inner core may be shape-shifting, new research suggests. The study, published Feb. 10 in the journal Nature, looked at earthquake waves that have skimmed the edge of the inner ...
The spinning of Earth’s inner core is slowing down. Is this how it all ends? The movement of Earth’s inner core is slowing. Nobody can say why.
As the Earth gradually cools, the inner core expands outwards at the surrounding iron-rich liquid "freezes." That said, it is still extremely hot, at least 5,000 Kelvin (K) (4726.85 degrees Celsius).
USC scientists have made a groundbreaking discovery about the nature of Earth’s enigmatic inner core, revealing for the first time that this 1,500-mile-wide ball of iron and nickel is changing.
The Earth's inner core is a hot, dense and solid ball made of iron and nickel, located 3,200 miles (5,150 kilometers) below our feet. It is surrounded by a liquid iron-nickel outer core, encased ...
The inner core is the Earth's innermost layer, with a radius of about 760 miles—about the same size as the moon—and is a solid ball of iron and nickel at the center of our planet. Due to its ...
Deep beneath our feet, at a staggering depth of over 5,100km, lies Earth's inner core—a solid ball of iron and nickel that plays a crucial role in shaping the conditions we experience on the ...
