Earth's Inner Core Is Changing Shape

Earth's Inner Core Is Mysteriously Changing Shape, Study Reveals
A new, detailed probe of Earth's heart reveals that the rotating inner core doesn't just change in rotation speed – it also appears to change in shape, with subtle variations appearing in the way acoustic waves propagate through the planetary center.
‘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 Solid Inner Core Is Changing Shape, New Study Finds
Researchers found evidence that the Earth's inner core is changing shape, suggesting unseen processes affecting its movement over time.
Earth's Inner Core Is Changing Shape And It Could Alter Our Day's Length
The rotation of the Earth's inner core is tied to the planet's overall rotation. Changes in the core's structure or movement can influence how fast or slow the Earth spins on its axis. Even minute alterations in the core's rotation can lead to changes in the length of a day by fractions of a millisecond.
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.
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 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.
What lies at the center of the Earth? The answer keeps changing.
A new study out this week said that the Earth's inner core is less solid than previously thought. Scientists still have ...

Earth’s inner core is less solid than we thought
Earth’s core is pretty dynamic. Its spin speeds up and slows down based on how its two primary layers are behaving. As we improve the waveform techniques used to study the deepest layer ...

Earth’s Mysterious Inner Core Is Changing Shape
This process drives churning in the outer core, which sustains Earth’s magnetic field. Changes in the inner core’s rotation can also affect the length of our day. “Ideally, we’d like to ...
