Plate Tectonics Theory Evidence Plate tectonics is a relatively recent theory having been proposed in the late 1960s and finally being verified enough so that it could be put in the introductory geology textbooks in the 1980s (remember all of the peer review, error-correction process that happens before something is fit to print in a textbook). What finally made scientists accept the theory? Today we can easily measure plate motion using GPS sensors on either side of plates. As in any robust scientific theory there are multiple lines of evidence supporting the theory. For plate tectonics, the evidence is continental motion, seafloor spreading, earthquake and volcano locations, and the difference between the seafloor crust and continental crust. I will give just a brief outline of the evidence for plate tectonics here. See the nice, detailed presentation from the USGS's Dynamic Earth online text . Continental motion:
