The evidence that supports Wegner's hypothesis is that in 1947 , a group of scientisits noticed two things about the Mid- Atlantic Ridge. The first thing that the scientists noticed was the sediment that covers the sea floor is thinner and younger closer to a ridge than it is farther from a ridge. Second, scientists learned that the ocean floor is very young. Radiometric dating shows that the sea floor closer to the mid-ocean ridge are younger, than the ones farther.
Wegner's hypothesis suggests that continents were once connected in a single landmass called Pangaea, which later split apart due to plate tectonics. Evidence supporting this includes the similar shapes of continental margins, the distribution of fossils and rock formations across continents, and the matching geological features and mountain chains on opposite sides of the Atlantic Ocean. Magnetic reversals recorded in oceanic rocks also provide evidence for seafloor spreading and plate movement.

What edvience supported Wegners hypothesis?
Wegner's hypothesis of continental drift was supported by evidence such as the jigsaw-like fit of continents, similarities in rock formations and geological structures across continents, and matching fossil evidence found on different continents. Additionally, the discovery of mid-ocean ridges and magnetic striping on the ocean floor provided further evidence for the movement of continents.
What was Alfred wegners hypothesis about the continents?
Alfred Wegener proposed the hypothesis of continental drift, suggesting that the continents were once joined together in a single landmass called Pangaea. He proposed that the continents had drifted apart over time to their current positions. This idea laid the foundation for the theory of plate tectonics.
What was Wegners evidence that Pangaea once existed?
Wegener's evidence for Pangaea included the fit of the continents like a jigsaw puzzle, similar rock formations and fossils on different continents, and matching mountain ranges across continents. Additionally, the distribution of climate-sensitive organisms and glacial deposits provided further support for the theory of continental drift.
What was the main counterargument against wegners evidence?
The main counterargument against Wegener's evidence for continental drift was the lack of a plausible mechanism to explain how continents could move across Earth's surface. Scientists at the time struggled to understand how the solid rock of the Earth's crust could move large distances.
Who first suggested there was a pangeae or a continental drift?
In the year 1911 a German meteorologist noticed that the contents looked like the fit in together. Wegner (Veg-ner) did some research regarding the subject. Wegners theory states that parts of the Earths crust slowly drift atop a liquid core. Landforms fossils and climates helped support his theory. There were two big flaws in Wegners theory; there was no feasible explanation for the cause of Continental drift because you can be on top of something liquid and not move and that there was no evidence that continents plowed through the ocean basin. No one believed Wegner's theory. 20 years later Wegner died and then after another 20 years we developed the technology and proved Wegners theory.
What was wegners hypothesis?
The hypothesis you are looking for is continental drift.
What was Alfred wegners hypothesis about Pangaea?
Alfred Wegner's hypothesis about Pangea was that it is one whole big continent.
Why scientists rejected wegener's hypothesis of continental drift?
Scientist rejected Wegners hypothesis of continental drift at first because he did not have enogh evidence to support his theory. He failed to provide a suitable mechanism that could cause the continents to move.
What Alfred wegners hypothesis?
He discovered Pangaea; once all the continents were together, as one big continent.
What edvience supported Wegners hypothesis?

Why did scientists argue against Wegners continental drift hypothesis?
Because wegner didnt have proof to show what caused mountains.
The scientists of wegeners time should have accepted his hypothesis why or why not?
yes because they didnt know how wegners inteligence was and they should have tried it in the firts place anyway it would have helped relize that his hypothesis waas correct when they dobt of him!

Why was wegners continental drift hypothesis rejected by the scientific community?
because he couldn't explain what forces caused the continents to move... :D yup that's why
Why did scientists reject wegners theory of continental drift?
Scientists rejected Wegener's theory of continental drift initially because he did not have a plausible mechanism to explain how the continents moved. Additionally, at the time, there was insufficient evidence to support his hypothesis. It was only later, with the development of plate tectonics theory, that Wegener's idea gained widespread acceptance.
How did Hess's hypothesis address the major weaknesses of Wegener's theory?
Hess's hypothesis of seafloor spreading provided a mechanism for continental drift, explaining how and why continents moved apart. It also incorporated evidence from oceanic crust age, magnetic striping, and sea-floor topography, filling the gaps in Wegener's original theory. This new explanation laid the foundation for the development of the theory of plate tectonics.
