Evidence That Support The Sea Floor Spreading Theory

Eruptions of molten material magnetic stripes in the rock of the ocean floor and the ages of the rocks themselves.

Evidence that support the sea floor spreading theory.

Convergence supports the theory of seafloor spreading. Seafloor spreading theory that oceanic crust forms along submarine mountain zones and spreads out laterally away from them. These age data also allow the rate of seafloor spreading to be determined and they show that rates. In 1965 a canadian geophysicist j.

Evidence of sea floor spreading. Several types of evidence supported hess s theory of 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. The regions that hold the unique record of earth s magnetic field lie along the mid ocean ridges where the sea floor is spreading.

Tuzo wilson combined the continental drift and seafloor spreading hypotheses to propose the theory of plate tectonics. Harry hess s hypothesis about seafloor spreading had collected several pieces of evidence to support the theory. As upwelling of magma continues the plates continue to diverge a process known as seafloor spreading samples collected from the ocean floor show that the age of oceanic crust increases with distance from the spreading centre important evidence in favour of this process. Evidence of molten material in the year of 1960 scientists derived ocean floor in alvin.

Evidence of seafloor spreading theory 1. Evidence for sea floor spreading. Samples of the deep ocean floor are evidence of seafloor spreading because the basaltic oceanic crust and overlapping sediment become younger. This evidence led scientists to look again at wegener s hypothesis of continental drift.

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. Evidence of magnetic stripes magnetic poles have been reversed which is magical for the scientists. Tuzo said that earth s crust or lithosphere was divided into large rigid pieces called plates. Evidence from molten material.

Paleomagnetism led the revival of the continental drift hypothesis and its transformation into theories of sea floor spreading and plate tectonics. Strong evidence of seafloor spreading and plate tectonics. Rocks had shaped like toothpaste and squeezed pillows.
