Plate tectonics guided reading and study seafloor spreading answer key ) The “father” of the Continental Drift theory is Alfred Wegener, a German scientist who believe that the continents were once all connected, creating one super continent called Pangaea. True or False? The theory of seafloor spreading explains that Earth's continents move because they ride atop ocean crust as it moves away from ocean ridges. World War II and Plate Tectonics Much of the evidence for plate tectonics comes from the structure of the ocean sea floor, and its discovery is largely due to submarines. This process was first proposed by Harry Hess in the 1960s and provided key evidence supporting the theory of plate tectonics. 2 Sea-Floor Spreading (pages 254–260) This section discusses sea-floor spreading and subduction zones, and evidence for sea-floor spreading. 11.
