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.
Goodbye to everything we knew about the Earth's core: Scientists find hidden structure inside
Our planet, Earth, is structurally composed of a series of concentric internal spherical layers that are divided into: crust, upper mantle, mantle, outer core and inner core. Every
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.
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.
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.
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 […]
