What is polar displacement?

Answer 1

Polar displacement. I think what your referring to if we are talking in a geological sense is actually called polar wandering and it is the apparent movement of the north and south poles over geological time however the poles are actually not the objects moving it is the continental landmasses under plate tectonics moving the land under the poles.

The poles do move slightly before they reverse however plate tectonics is the main cause of polar wandering.

Answer 2

Polar displacement is the movement of a celestial body's position, commonly measured in polar coordinates such as distance and angle relative to a reference point. In geophysics, it can refer to the shift in the Earth's rotation axis due to factors like ice melting and tectonic movements.
