Wandering the north magnetic pole through geologic time. although students of ancient rock magnetism regard this path as fairly well established, there is no conclusive proof that the geographic pole followed the same path or that the continents maintained their same positions during this lengthy period. Notice also that there are no signs of frigid conditions or glacial action in northeastern Asia during the periods when the pole was supposed to be in that vicinity. Stokes, 1960, p. 168.

Wave refraction. The manner in which waves are refracted on an irregular shoreline. It is assumed that the water is deeper off the bay off the headlands. Consider that the original wabe is divided into three equal segments A-B, B-C, and C-D. Each segment has the same potential energy. But observe that by the time the wave reaches the shore the energy of A-B and C-D has concentrated along the short shoreline of headlands A'-B' and C'-D', while the energy of B-C has been dispersed over a greater front (B'-C') around the bay. Thus there is more energy available for erosion per unit of shoreline on the headlands than there is along the bay. Leet and Judson, 1958, p. 310.
