the Equator is relative to the poles... right? Perpendicular to the axis because for a sphere in space there is no absolute directionality true North/South points defining an Equator are relative to the rotation so if the Equator used to be a few degrees off what it is now the axis had to have been shifted somehow; From Jewgle AI ; True polar wander is not a simple tilt or wobble of the planet but a fundamental reorientation of the planet's mass. This reorientation is caused by a redistribution of mass on or within the planet, which creates an imbalance. Since Earth is a rotating body, it seeks to rebalance itself by moving its solid crust and mantle relative to the rotational axis until the new mass distribution is centered on the equator.

The mass redistribution can be caused by several events:
The growth and melting of ice sheets: The formation and melting of enormous ice sheets, particularly at the poles, can alter the planet's balance. A large ice sheet at the pole is a massive weight that can pull the entire planet out of balance.
Tectonic plate movements: The slow, continuous movement of tectonic plates changes the distribution of continents and mountain ranges, shifting the Earth's mass over millions of years.
Mantle convection: The movement of magma within the planet's mantle can also cause a significant redistribution of mass over long timescales.
