Earth’s inner core isn’t just slowing; it’s also shape-shifting, study finds
Previous research has found that the rotation of the inner core is slowing down relative to the rotation of the external crust, which may cause minute changes in Earth’s rotation and subtly affect the ...
The Earth’s Core Is Not as Solid As We Thought, Yet Another Study Speculates
A new study of decades worth of seismogram data shows that the surface of Earth’s iron and nickel core is more malleable than scientists thought.

What lies at the center of the Earth? The answer keeps changing.
Located 3,000 miles below the Earth’s surface, the inner core is anchored by gravity within the molten liquid outer core. It's believed to play an important role in maintaining the planet’s ...

Earth's outer core may hold a hidden 'doughnut'
They found an odd ring around the outer core's equator, where earthquake waves move more slowly than in surrounding regions. Earth's outer core is made up of liquid iron and nickel and surrounds ...

What Drives Earth's Magnetic Field?
In the Earth (see image below right), the liquid metal that makes up the outer core passes through a magnetic field, which causes an electric current to flow within the liquid metal. The electric ...

Earth’s Mysterious Inner Core Is Changing Shape
He and his colleagues report the finding today in Nature Geoscience. Earth’s inner core is surrounded by an outer core, and the interface between the two, around 5,100 kilometres below the ...

‘It’s almost science fiction’: Scientists say the shape of Earth’s inner core is changing
Earth’s innermost layer is a hot, solid ball of metal surrounded by a liquid metal outer core. For decades, planetary scientists suspected that the solid inner core deformed over time as it spun.

What's at the center of the Earth?
"The transition from the innermost (solid) ball to the outer shell of the inner core (also solid shell) seems rather gradational than sharp," explains study coauthor Dr. Thanh-Son Phạm.

Earth’s inner core isn’t just slowing, it’s also shape-shifting, study finds
But a new study has found that its edges are softer than realized and actually changing shape as they press against the liquid iron and nickel in Earth’s outer core. “The molten outer core is ...
