Earth's inner core is solid, but the outer core is liquid. That means the inner core is suspended in liquid, like the insides of a chocolate-covered cherry, leaving it weirdly free to move around. #Core#BeFree
Why would Earth's core spin (slightly!) faster or slower than the surface? 1) the gravity of the mantle is pulling on it. 2) magnetic fields from the outer core grab onto it. If we can measure these effects, we learn a lot about the geomagnetic field that keeps us all safe. #Core#Earth
