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 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.
Earth’s inner core isn’t just slowing; it’s also shape-shifting, study finds
Previous research has found that the rotation of the inner core is slowing down relative to the rotation of the external crust, which may cause minute changes in Earth’s rotation and subtly affect the length of a day. Although these time changes are only estimated to be a matter of milliseconds a year, they accumulate over eons.
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 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
