WFS News: Earth’s core and mantle separated in a disorderly fashion

@WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev Plumes of hot rock surging upward from the Earth’s mantle at volcanic hotspots contain evidence that the Earth’s formative years may have been even more chaotic than previously thought, according to new work from a team of Carnegie and Smithsonian scientists published in Nature. It is well understood […]

WFS News: Satellites help discover a jet stream in the Earth’s core

@WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev A jet stream within the Earth’s molten iron core has been discovered by scientists using the latest satellite data that helps create an ‘x-ray’ view of the planet. Lead researcher Dr Phil Livermore, from the University of Leeds, said: “The European Space Agency’s Swarm satellites are providing our […]

Clues to Earth’s ancient core

Old rocks hold on to their secrets. Now, a geophysicist at Michigan Technological University has unlocked clues trapped in the magnetic signatures of mineral grains in those rocks. These clues will help clear up the murky history of Earth’s early core. The journal Earth and Planetary Science Letters published a paper on the subject earlier […]

Iron in Earth’s Core Weakens Before Melting

The iron in the Earth’s inner core weakens dramatically before it melts, explaining the unusual properties that exist in the moon-sized solid centre of our planet that have, up until now, been difficult to understand. Scientists use seismic waves — pulses of energy generated during earthquakes — to measure what is happening in the Earth’s […]
