How Did Seafloor Spreading Revive Alfred Wegener’s Ideas About Continental Drift? (Question)

How did seafloor spreading contribute to the revival of Alfred Wegener’s theories of continental drift? In addition, the discovery of magnetic reversals provided more support for the sea floor spreading concept, as it demonstrated that rocks on each side of the ridge displayed the same polarity equally.

  • This is false, as Wegener claimed that the continents themselves were in the process of moving. The tectonic plates are the ones that move. When the breakup of Pangea occurred, Wegener was motivated to include this as evidence in favor of his continental drift theory.

How did seafloor spreading support Wegener’s theory of continental drift?

Sea floor spreading is the phenomenon of new sea floor being formed as a result of the formation of mid-ocean ridges in the ocean. This is false, as Wegener claimed that the continents themselves were in the process of moving. The breakup of Pangea was caused by sea floor spreading, which inspired Wegener to include this as evidence in favor of his continental drift hypothesis.

How did Hess seafloor spreading show that Wegener was correct about plate tectonics?

In 1962, he introduced a geologic process to account for Wegener’s shifting continents, which was published in Science. Hess demonstrated that Wegener’s fundamental hypothesis was correct and clarified the mechanism that separated the formerly united continents into the seven continents that we are familiar with. The continents are firmly linked to the plates and do not move independently of the plates.

Is Alfred Wegener responsible for the theory of continental drift seafloor spreading plate tectonics or a combination of these explain your answer?

Alfred Wegener discovered evidence in 1912 that the continents are moving, but geologists dismissed his views because he was unable to explain what forces were moving them. A little more than 50 years later, Harry Hess validated Wegener’s theories by utilizing evidence of seafloor spreading to explain what caused continents to migrate.

Why did the idea of continental drift become more accepted after seafloor spreading was proposed?

Is it possible that the notion of shifting continents became more broadly accepted after the proposal for seafloor spreading became public? The missing connection was the spreading of the seafloor. continents are NOT pushing through ocean crust, as he first believed; rather, continents are more like passengers on a train, riding alongside the ocean crust as it gradually advances away from ocean ridges.

What is the hypothesis of seafloor spreading as defined by Harry Hess?

The seafloor spreading theory was presented by the American geophysicist Harry H. Hess in 1960, and it has since gained widespread acceptance. The spreading of material results in an ocean bottom that is increasingly younger, and the movement of material is assumed to have resulted in the migration, or drifting away, of the continents.

How does seafloor spreading fit into the idea that continents move about on Earth’s surface?

When it comes to the assumption that continents migrate over the Earth’s surface, how does seafloor spreading fit in? As a result of the floor’s pressure on the plates, which is forming “new earth,” the planet’s surface will move around, forcing the continents to shift as well.

What is the major evidence that sea floor spreading creates new lithosphere explain your answer?

Because the record of magnetic reversals is being transported away from each side of a mid-ocean ridge’s spreading center, it indicates that molten rock is forming new lithosphere.

What observation led Alfred Wegener’s theory of continental drift hypothesis?

As Alfred Wegener proposed, continental drift happened as continents cut through the ocean bottom, just like this icebreaker is doing now as it ploughs through sea ice. Wegener’s book The Origin of Continents and Oceans, originally published in 1915, was a collection of his theories and evidence for his theories.

Why was Wegener’s idea of continental drift rejected?

Because Wegener’s idea did not provide a mechanism for shifting the continents, it was rejected mostly because it was lacking in detail. He believed that the power of the Earth’s rotation was sufficient to enable continents to move, but geologists recognized that rocks are far too strong for this to be true, so he abandoned his theory.

How did the use of sonar change scientists ideas about ocean floor topography?

What impact did the use of sonar have on scientists’ perceptions of the topography of the ocean floor? Having the ability to view structures on the ocean floor such as guyots, the mid-oceanic ridge, and trenches on the ocean floor helps scientists better understand how plates interact as they move.
