Earth's Inner Core Is 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.
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 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 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 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
Studying Earth’s core presents a unique challenge for scientists. Obviously, sending a field team to the core is out of the question, so there’s no hope of getting samples and much of the time, it can be hard to observe changes from the surface,
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
