A system of end moments and loads was used to shape the linearly thickness-tapered plate into a parabolic cylinder,and a mathematical model was deduced to predict the shape accuracy of the thin Plate Tectonics - The Australian MuseumPlate Tectonic processes .Since the 1950s,several discoveries have led to a new understanding of how the Earth works.This includes Plate Tectonics,which explains the structure of the Earth's lithosphere (outer shell) and the forces that drive changes in its structure.Tectonics comes from the Greek word tekton,meaning builder.
