Earth, inner core

Earth’s inner core is deforming—here’s what we know
In a nutshell Scientists have discovered that Earth’s inner core isn’t just changing its rotation speed – it’s actually deforming at its surface. This is the first time such structural changes have been observed on human timescales.
Earth’s Core Is Changing Shape
A new study shows that the inner core changed shape in just a few decades, challenging previous assumptions and revealing hidden dynamics deep within Earth.
Scientists discover Earth's inner core isn't just slowing down — it's also changing shape
The surface of Earth's inner core appears to be dynamic, changing shape as it rotates, earthquake waves reveal.
Earth’s inner core is not solid, it is 'shape-shifting' - time for textbooks to be rewritten
New study reveals that Earth's inner core is undergoing unexpected structural changes, challenging long-held assumptions about its solidity.
Scientists discover yet another change to Earth’s inner core: Its shape
Scientists found that the inner core’s structure changes as it rotates. It deforms at its border, potentially accumulating more material in some areas and less in others — almost like creating hills and valleys.
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 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.
What lies at the center of the Earth? The answer keeps changing.
A new study out this week said that the Earth's inner core is less solid than previously thought. Scientists still have questions, though.
