Researchers from China have confirmed an 8.5-year Inner Core Wobble (ICW) in Earth’s polar motion and length-of-day variations, revealing a static tilt of about 0.17 degrees between the inner core and mantle, challenging long-standing assumptions about Earth’s internal dynamics.
According to a new study published in the journal Nature Geoscience, the inner core of the Earth may have stopped rotating faster than the rest of the planet around 2009 and then turned in an opposite direction.
Seismic waves are helping scientists to plumb the world’s deepest mystery: the planet’s inner core.Thanks to a novel application of earthquake-reading technology, a research team at the University of Illinois and colleagues at Nanjing University in China hav
Scientists believe they have achieved the first accurate estimate of how much faster Earth's core is rotating compared to the rest of the planet. University of Cambridge study has discovered that earlier estimates of one degree quicker each year were wrong. The
