Reply to comment by shiruken in Earth's inner core seems to be slowing its spin according to new research published in Nature Geoscience. The study authors suggest this might be part of an approximately 70-year cycle where the core speeds up and slows down relative to the rest of the planet. by shiruken
Do you mind explaining how the core and the rest of the planet can have different rotation speeds? I haven’t taken science courses since college so I’m ignorant to the subject matter.
