Evidence That Support The Sea Floor Spreading Theory

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

Evidence that support the sea floor spreading theory.

Tuzo wilson combined the continental drift and seafloor spreading hypotheses to propose the theory of plate tectonics. It was the greatest support of sea fall spreading. Evidence for sea floor spreading. Several types of evidence supported hess s theory of sea floor spreading.

Harry hess s hypothesis about seafloor spreading had collected several pieces of evidence to support the theory. Rocks had shaped like toothpaste and squeezed pillows. These plates float atop an underlying rock layer called the asthenosphere. Strong evidence of seafloor spreading and plate tectonics.

Evidence of seafloor spreading theory 1. Evidence of molten material in the year of 1960 scientists derived ocean floor in alvin. The regions that hold the unique record of earth s magnetic field lie along the mid ocean ridges where the sea floor is spreading. Convergence supports the theory of seafloor spreading.

This idea played a pivotal role in the development of the theory of plate tectonics which revolutionized geologic thought during the last quarter of the 20th century. Samples of the deep ocean floor are evidence of seafloor spreading because the basaltic oceanic crust and overlapping sediment become younger. The second piece of evidence in support of continental drift came during the late 1950s and early 60s from data on the bathymetry of the deep ocean floors and the nature of the oceanic crust such as magnetic properties and more generally with the development of marine geology which gave evidence for the association of seafloor spreading along. Paleomagnetism led the revival of the continental drift hypothesis and its transformation into theories of sea floor spreading and plate tectonics.

Evidence of magnetic stripes magnetic poles have been reversed which is magical for the scientists. This evidence was from the investigations of the molten material seafloor drilling radiometric age dating and fossil ages and the magnetic stripes. Evidence of sea floor spreading. Evidence from molten material.

This evidence led scientists to look again at wegener s hypothesis of continental drift. These age data also allow the rate of seafloor spreading to be determined and they show that rates. In 1965 a canadian geophysicist j.
