The Development of Plate Tectonics

The video explores the theory of plate tectonics, starting with its basic principles and significance. It delves into Alfred Wegener's hypothesis of Pangaea and its initial rejection. The video then discusses magnetic evidence supporting plate tectonics, including studies of magnetic minerals and the discovery of magnetic striping on the seafloor. Harold Hess's contributions through ocean floor mapping and J. Tuzo Wilson's explanations of seamounts and transform faults are highlighted. The video concludes with Wilson's unified theory of plate tectonics and the concept of the Wilson cycle.
