Earth's Inner Core Found to Be Changing Shape in Groundbreaking Study
- The inner core of Earth may have changed shape by 100m or more in height in places over the past 20 years, according to Prof John Vidale.
- Earth's core produces a magnetic field that protects life from the Sun's radiation, and the inner core spins independently from the outer core and the rest of the planet.
- Understanding how Earth's core works is essential to understanding the magnetic field that protects the planet, and whether that could weaken or stop.

The Earth's inner core is changing shape, study reveals
Deep within Earth, a hidden transformation is underway. Scientists have discovered that the inner core’s surface is changing shape, challenging previous assumptions about its solid nature. This dynamic activity could influence Earth’s rotation and magnetic field Deep within the Earth, a dramatic transformation is underway. A new study from the University of Southern California (USC), published in Nature Geoscience, has revealed evidence of signi…
Earth’s Solid Inner Core Is Changing Shape, New Study Finds
Earth’s solid inner core. Credit: Argonne National Laboratory / CC BY-NC-SA 2.0 Scientists have found new evidence that the Earth’s inner core, a dense metal ball deep within the planet, may not be perfectly solid and is changing shape. Researchers say its outer layer has changed shape in recent decades, raising new questions about the dynamics of the planet’s center. The inner core, made mostly of iron and nickel, is about 1,500 miles wide and …
Until now, researchers assumed that the Earth's core was solid. A new study now shows that the Earth's core is more malleable than previously thought.
Within only 20 years, the earth's core has deformed – researchers report this. Their analyses show how little we know about the mysterious interior of the planet.
