New York, Jan 24 (Ians) Earthquake data has hinted that the inner core of the Earth has stopped rotating faster than the rest of the planet, but not all researchers agree, according to a Nature report.
The rotation of the Earth’s solid inner core may have recently paused and could be reversing, according to a study published in Nature Geoscience.
The authors showed evidence that oscillation in the rotation of the inner core coincides with periodic changes in the Earth’s surface system and that there is an interaction between different layers of the Earth.
Earth’s inner core is made mostly of solid iron, and can rotate separately from the outer parts of the planet.
The liquid outer core essentially decouples the 2,400 km-wide inner core from the rest of the planet, so the inner core can spin at its own pace.
“We were quite surprised,” said Yi Yang and Xiaodong Song,...
