Magnetic Evidence for Seafloor Spreading Explains how magnetic polarity frozen into seafloor basalts reveals evidence for the creation of new seafloor. AnswerEvidence for Sea-Floor Spreading. Fossils of the Mesosaurs an ancient freshwater reptile found in South America and Africa indicate that the two continents could have once been one solid continent that drifted apart.

In the 1960s geologist Harry Hess proposed that the sea floor was moving outward from the midoceanic ridges. Eruptions of molten material magnetic stripe miah92 miah92 11212019 Biology Middle School answered What property was used as evidence to support seafloor spreading 1 See answer miah92. Depending on the theory used to interpret them or what you were actually looking for.

The age of Earths oceanic crust can be presented to show the pattern of seafloor spreading at the global scale. The study area was divided into a series of 1 km1 km square grids. Measurements of the thickness of marine sediments and absolute age determinations of such bottom material have provided additional evidence for seafloor spreading.

Keeping this in view what evidence supports the theory of seafloor spreading. Magnetic symmetry was the first evidence that lead to the theory of sea floor spreading. His theory of sea floor spreading maintained that new basaltic oceanic crust forms at a midoceanic ridge and is slowly pushed away on both sides toward the continents as more new crust is produced.

The secret of seafloor spreaeding is nothing it is just plain old seafloor spreading Paleomagnetic evidence was used to confirm which of. Evidence for seafloor spreading has come from fossils in South America and Africa and magnetic minerals on the ocean floor. During World War II submarine warfare caused the intense study of magnetism on the ocean floor.

Fields edit Paleomagnetism is studied on a. Used as evidence for sea-floor spreading. Then the weights of predictive maps were calculated and used to test maps predictive capacity.

Sea floor spreading where new material appears at seams on the sea floor and seems to have moved and is moving to either side can be used by those who are interested in the Expanding Earth theory as evidence of the Earth growing in the past or even now. The magnetic symmetry made spotting local abnormalities like a. What evidence was used to Support Sea Floor Spreading 1.

Then in 1963 Morley Vine and Matthews showed that marine magnetic anomalies provided evidence for seafloor spreading. What is the evidence for seafloor spreading. Eruptions of molten material magnetic stripes in the rock of the ocean floor and the ages of the rocks themselvesThis evidence led scientists to look again at Wegeners hypothesis of.
