According to a study published in Nature Geoscience this week, the rotation of Earth’s solid inner core may have recently halted and could potentially be reversing.
These findings suggest that changes in the rotation of the inner core could occur on a decade-long scale and could provide insights into the ways in which processes deep within the Earth impact its surface.
The Earth’s inner core is distinct from the rest of the solid Earth as it is encased by a liquid outer core, which allows it to rotate independently from the rotation of the Earth as a whole.
