Webb26 aug. 2015 · Continental Drift, Sea Floor Spreading and Plate Tectonics Plate Tectonics is a theory developed in the late 1960s, to explain how the outer layers of the Earth move and deform. The theory has caused a revolution in the way we think about the Earth. Since the development of the theory, geologists have had to reexamine almost every aspect of ... WebbPlate tectonics refers to the global system of coupled boundaries along mid-ocean ridges, subduction zones and transform faults on Earth. It operates through continental drift, seafloor spreading and lithospheric subduction, shaping the Earth surface throughout geological time.
