Earth, inner core

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
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 Inner Core Appears To Have Changed Shape In The Last Two Decades
A new study has found evidence that the Earth's inner core may have changed shape. Far from taking place over geological timescales, the changes appear to have taken place within the last two decades.
Earth's inner core may have changed shape, say scientists
The findings shed light on a deeply mysterious part of Earth that is key to life on our planet.
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.
