Because surface of the earth is spherical, all of the horizontal movements on the surface are rotation indeed. The centrifugal torsion caused by earth rotation is the reason that the continents move of the pole. It makes the pole drift and the crust deformed. It is brought to light that polar migration is one of the causes of crustal movement and earthquake.
