Are you curious about the inner workings of our planet? In this video, we dive into new research that shows the Earth's core is no longer spinning faster than the surface. The inner core floats in a liquid metal outer core, allowing it to spin independently and relative to the Earth's surface, like a swing. The study estimates that one cycle of this swing lasts about seven decades. Scientists have observed that the inner core started spinning faster in the early 1970s, but has been slowing down and syncing with the Earth's rotation since 2009. Watch now to learn more about this fascinating discovery.
