Earth, inner core

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.
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.
‘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 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 Has Warped Over the Past Two Decades, Scientists Say
At the center of our planet is a very hot rotating ball of mostly iron and nickel (sorry Journey to the Center of the Earth fans). Scientists infer features of this innermost geographic layer—like the fact that it’s divided into a liquid outer core and a solid inner core—by analyzing how it distorts seismic waves caused by earthquakes.
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.
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.
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.
Shocking change in Earth’s core could alter everything we knew
A new study in Nature Geoscience reveals insights about the Earth’s core. While we often learn about the inner and outer cores, research is ongoing to under
Length of each day may have changed after stunning new discovery at Earth's core
Researchers are now examining surprising structural changes occurring within the Earth's core that may have slightly affected the length of each day. Although scientists have long recognized changes in the Earth's inner core,
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 […]
