Scientists say shape of Earth’s inner core is changing

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 Mysterious Inner Core Is Changing Shape
Earth’s core is transforming, which could affect the length of our 24-hour day, Earth’s magnetic field, and more
‘It’s almost science fiction’: Scientists say the shape of Earth’s inner core is changing
Researchers studying decades of earthquake data say they have found the first evidence that, in addition to spinning backward, Earth’s inner core in changing shape.
Earth’s inner core isn’t just slowing, it’s also shape-shifting, study finds
USC scientists have made a groundbreaking discovery about the nature of the Earth's enigmatic inner core, revealing for the first time that this 1,500-mile-wide ball of iron and nickel is changing.
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 Has Warped Over the Past Two Decades, Scientists Say
At the center of our planet is a very hot rotating ball of mostly iron and nickel (sorry Journey to the Center of the Earth fans). Scientists infer features of this innermost geographic layer—like the fact that it’s divided into a liquid outer core and a solid inner core—by analyzing how it distorts seismic waves caused by earthquakes.
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.
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 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 Slowing Down — and May Not Be Entirely Solid
The surprise discovery of earth’s core composition may debunk previous assumptions on the solidity of the planet.
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.
