Earth’s solid metal core may be soft on outside

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.
Scientists accidentally discover Earth's inner core is less solid than expected
For a long time, scientists thought the Earth's inner core was a solid ball of metal, sort of like a planet within a planet that sits some 3,000 miles (4,828 kilometers) below the surface.
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.
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.
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.
‘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 Is Changing Shape, And Scientists Are Puzzled As To Why This Is Happening
Not only is Earth’s inner core spinning and growing, but it’s also changing shape, according to new research. Our planet’s […]

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 ...

Earth’s Core Is Changing Shape
“What we’re observing in this study for the first time is likely the outer core disturbing the inner core,” explains Vidale. Turbulence in Earth’s molten outer core disrupts the boundary ...
