Jean Coulomb. Reidel, Dordrecht,pp., Dfl. Continental Drift, Sea Floor Spreading and Plate Tectonics Plate Tectonics is a theory developed in the late s, 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 ~sanelson/eens/ The effects of sea floor spreading on the neighboring continents has already been alluded to.

The long-standing theory of continental drift was given a direct stimulus when it became known. Only what is indispensable in this theory will be recalled, confined as far as possible to the geophysical ://   Ina Canadian geophysicist, J. Tuzo Wilson, combined the continental drift and seafloor spreading hypotheses to propose the theory of plate tectonics.

Tuzo said that Earth’s crust, or lithosphere, was divided into large, rigid pieces called plates. These plates “float” atop an underlying rock layer called the :// /continental-drift-and-seafloor-spreading. A geometrical model of the surface of the earth is obtained in terms of rigid blocks in relative motion with respect to each other.
