Earth, inner core

‘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 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.
Earth's inner core may have changed shape, say scientists
The inner core of Earth may have changed shape in the past 20 years, according to a group of scientists. The inner core is usually thought to be shaped like a ball, but its edges may actually have deformed by 100m or more in height in places, according to Prof John Vidale who led the research.
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
Researchers Uncover Mysterious Structural Changes in Earth’s Inner Core
A new study reveals that the Earth's inner core is undergoing a structural transformation. A new study by USC scientists, published in Nature Geoscience, reveals structural changes near the Earth's inner core,
