从全球范围看，岛屿几乎全在大陆块的东海岸，南极凸出，北极凹进；北半球陆地多，南半球海洋多，这应该是大陆长期向西向北纬６２°漂移运动的结果．利用ｕ场概念，讨论了大陆向西漂移的原因；并推知，大陆向北纬６０°运动是太阳在银道的近心点，及地球北极与银北极成６２°角等因素促成的 Globally, the islands are almost entirely on the east coast of the mainland. The Antarctic is convex with the North Pole recessed. The northern hemisphere has more land and the southern hemisphere has more oceans. This should be the result of a long-term continental movement of 62 ° west and north latitude. Using the concept of u-field, the reasons for the westward drift of the continent are discussed. It is also deduced that the movement of the continent to 60 ° north latitude is caused by the solar centripetal centerline and the 62 ° angle between the northern pole of the earth and silver north pole
