Didn’t we recently discover the core is solid?
Did we? The inner core maybe, but there’s definitely some liquid somewhere, cos of volcanoes.
It’s not something that is currently predictable though. We don’t have decent models for the magnetic field.
Well there’s magma under the crust but the core is solid.
The inner core is solid. The outer core is 2000km of liquid.
But the main point is that both of these layers could vary their spin, making long term predictions about the rotation of the crust inaccurate.
