Earth, inner core

Earth's inner core is slowing down and changing shape 🌍
The Earth's inner core, long considered a solid and stable sphere, may be quite different. A recent study suggests that its surface is undergoing structural transformations, challenging
Earth’s inner core is less solid than we thought
Earth’s core is located below the middle layer called the mantle and the outer layer –or crust. It consists of two main parts–a liquid outer core and a more solid inner core. The outer layer is made of liquid iron-nickel and is responsible for producing Earth’s magnetic field.
Earth’s inner core is deforming—here’s what we know
What is happening in Earth's inner core? Discover the implications of its deformation for seismic activity and navigation.
'A core problem': Earth’s slowing, reshaping heart could change everything we know
Earth’s inner core is shifting, slowing, and reshaping. Scientists study its impact on magnetic fields, pole movement, and planetary evolution, revealing hidden Earth processes.
Scientists Detect Shape-Shifting Along Earth’s Solid Inner Core
Scientists of course cannot cut into Earth and directly observe its insides. Instead, their knowledge is inferred from the vibrations generated by earthquakes that pass through the planet. The speed and the direction of the seismic vibrations change depending on the density and the elasticity of the rocks.
Earth’s Inner Core Is Changing Shape, Study Finds, Indicating Even More Dynamic Shifts Deep Within Our Planet
Seismic wave data previously suggested the Earth’s hot inner core is slowing its spin. Now, researchers say it’s also deforming around the edges
Earth’s inner core isn’t just slowing, it’s also shape-shifting, study finds
The planet’s inner core was previously thought of as a hard, solid sphere. But a new study has found that its edges are softer than realized and actually changing shape.
