Nothing lasts long under the same form. I have seen what once was solid earth now changed into sea, and lands created out of what was ocean. Ancient anchors have been found on mountaintops.
In a polar region there is continual disposition of ice, which is not symmetrically distributed about the pole. The earth’s rotation acts on these unsymmetrically deposited masses, and produces centrifugal momentum that is transmitted to the rigid crust of the earth. The constantly increasing centrifugal momentum produced this way will, when it reaches a certain point, produce a movement of the earth’s crust over the rest of the earth’s body, and this will displace the polar regions toward the equator.
