What Drives Plate Motion?

Authors: Yongfeng Yang

Plate motion was widely thought to be a manifestation of mantle dynamics. However, an in-depth investigation shows this understanding incompetent. Here we propose, the daily tides yield varying pressures between oceans, the application of these pressures to the continent's sides forms enormously unequal horizontal forces, the net effect of these forces provides lateral push to the continent and may cause it to move horizontally, further, the moving continent by basal drag entrains its adjacent crust to move, these totally give birth to plate motion. A roughly estimation shows that the oceanic tide-generating force may independently give South American, African, Indian, and Australian continents a movement of respectively 2.8, 4.2, 5.6, and 6.3 cm/yr. Some torque effects may rotate North American and Eurasian continents, and a combination of two lateral pushes offers Pacific Plate unusual motion (nearly orthogonal to Australian plate’s motion).
