{wiki=Polar_wander}
Polar wander refers to the movement of the Earth's magnetic poles over time, which is different from the movement of the geographic poles. This phenomenon can occur due to changes in the Earth's mantle and crust, which can cause shifts in tectonic plates and changes in the distribution of mass within the Earth. As a result, the position of the magnetic poles can shift significantly over geological timescales.
