Tuzo said that earth s crust or lithosphere was divided into large rigid pieces called plates.

Evidence examples and explanations of seafloor spreading. Spreading rate is the rate at which an ocean basin widens due to seafloor spreading. This evidence led scientists to look again at wegener s hypothesis of continental drift. Evidence of sea floor spreading harry hess s hypothesis about seafloor spreading had collected several pieces of evidence to support the theory. Evidence for sea floor spreading.

This evidence was from the investigations of the molten material seafloor drilling radiometric age dating and fossil ages and the magnetic stripes. In 1965 a canadian geophysicist j. Tuzo wilson combined the continental drift and seafloor spreading hypotheses to propose the theory of plate tectonics. For example when scientists study the.
