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.
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 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 solid metal core may be soft on the outside: Study
The Earth’s inner core is changing shape and may be a little soft on the outside, scientific research suggests. A study published in Nature Geoscience this month evaluated seismic activity to determine what may be happening within the deepest parts of the planet.
Scientists left baffled after making discovery about Earth's core that could change everything they knew
Scientists at the University of Southern California have discovered the Earth's core is changing shape after analysing earthquake data.
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 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.
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
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 […]
