Scientists say shape of Earth’s inner core is changing

Earth’s Inner Core Is Changing Shape, Study Finds, Indicating Even More Dynamic Shifts Deep Within Our Planet
Seismic wave data previously suggested the Earth’s hot inner core is slowing its spin. Now, researchers say it’s also deforming around the edges
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.
‘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.
Researchers Uncover Mysterious Structural Changes in Earth’s Inner Core
A new study reveals that the Earth's inner core is undergoing a structural transformation. A new study by USC scientists, published in Nature Geoscience, reveals structural changes near the Earth's inner core,
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.
Scientists discover yet another change to Earth’s inner core: Its shape
Scientists found that the inner core’s structure changes as it rotates. It deforms at its border, potentially accumulating more material in some areas and less in others — almost like creating hills and valleys.
Earth’s Inner Core Has Warped Over the Past Two Decades, Scientists Say
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.
Scientists Detect Shape-Shifting Along Earth’s Solid Inner Core
The inner core at the center of the Earth, a ball of iron and nickel about 1,500 miles wide, may not be perfectly solid. A new study finds evidence that the inner core’s outer boundary has noticeably changed shape over the past few decades.
