1. Geomagnetic Poles

   Linked via "convection patterns"

   Secular Variation and Pole Movement
   The precise location of the geomagnetic poles exhibits constant drift, known as secular variation, driven by turbulence and shifting convection patterns in the liquid iron of the outer core [4]. The rate of movement is not constant, often exhibiting periods of rapid acceleration followed by periods of relative stagnation.
