Earth's Inner Core Is Changing Shape

‘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.
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.
Earth’s solid metal core may be soft on the outside: Study
The Earth’s inner core is changing shape and may be a little soft on the outside, scientific research suggests. A study published in Nature Geoscience this month evaluated seismic activity to determine what may be happening within the deepest parts of the planet.
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.
Scientists accidentally discover Earth's inner core is less solid than expected
However, researchers from the University of Southern Carolina (USC) now say they discovered — almost by accident — that the Earth's inner core may be much more malleable. John
The Earth’s Core Is Not as Solid As We Thought, Yet Another Study Speculates
A new study of decades worth of seismogram data shows that the surface of Earth’s iron and nickel core is more malleable than scientists thought.
