Earth’s inner core may have slowed its rotating and could have started to move more slowly than the mantle, according to a new study.
Seismic waves from earthquakes that have moved through the inner core of the Earth over the past 60 years have been examined by scientists to see how fast it is spinning.
And the surprising outcome appears to show that while there were previous differences in the seismic records, since 2009 they have remained roughly the same.
