Earth, inner core

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.
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
Earth’s inner core is not solid, it is 'shape-shifting' - time for textbooks to be rewritten
New study reveals that Earth's inner core is undergoing unexpected structural changes, challenging long-held assumptions about its solidity.
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 inner core has shifted shape over two decades, scientists discover
Earth's inner core has changed shape over the past 20 years. A team of scientists studied the core's behavior to understand why its rotation slowed down
Earth’s inner core changing shape? Scientists reveal it may have 'deformed by over 100 meters'
New research suggests that Earth's inner core, long believed to be stable, may be undergoing structural changes, including a possible shift in shape, shedding light on the mysteries beneath the planet
'A core problem': Earth’s slowing, reshaping heart could change everything we know
Earth’s inner core is shifting, slowing, and reshaping. Scientists study its impact on magnetic fields, pole movement, and planetary evolution, revealing hidden Earth processes.
Earth's inner core isn't just slowing, it's also shape-shifting, study finds
USC scientists have made a groundbreaking discovery about the nature of the Earth's enigmatic inner core, revealing for the first time that this 1,500-mile-wide ball of iron and nickel is changing.
