∙ 12y agoAlfred Wegener used evidence to figure out about Pangaea. Evidence like plant fossils and dinosaur fossils that belonged to the same thing, but was found in two separate continents. Scientists found that it had been a different climate in some continents then there is now. They had found other things too, like similar oil wells, and there were deep scratches in rocks that showed continental glaciers once covered South Africa.

What evidence did wegner have for continental drift theory?
Actually there is a lot of evidence that supported his evidence the big one was fossils of animals on distant continents and plants for example Glossopteris was one the strange reasons that Alfred was more than ever to prove his point.Edit:Alfred Wegener proposed that, using 19th century longitude determinations, Greenland had moved 1 mile away from Europe. However, this conclusion ended up being false due to false calculations. Still, Wegener discovered that every year San Diego moved 6 feet closer to Shanghai while Washington D.C. and Paris got 15 feet closer. In addition, Alfred Wegener discovered that related species, too small to swim across the ocean, were found on different continental plates, as well as similar fossils.Alfred Wegener's theory was rejected at first, however, because he was unable to explain the reason why the plates moved. Later, Arthur Holmes published his theory of thermal convection being the the thing that drove the plates apart. He also noted that the continents didn't "move" but were "carried" by larger pieces of the Earth's crust. Discoveries of the Mid-Ocean Ridge in addition to Harry Hess's work adds onto this theory of Wegener's.As this theory is the most complete theory concerning global dynamics, the roots of such lie in the curiosity and work of Alfred Wegener.
What proof of citizenship is needed to rent to illegal citizens?
There IS no proof of citizenship for illegal [citizens] aliens. I should say, there is no legal proof of citizenship for illegal aliens.
Is a Charles Harper printers proof more valuable than an artist proof?
yes
Can i put a camera under water if it's not water proof?
No. If it isn't water proof it will break.
Is there proof that the Mexican yam helps with gout?
There is proof that theMexican yam has components that can be helpful in gout but you would have to eat a truck load of it. this would be poisonous. There is no proof that you can treat gout with Mexican yams.
Who thought of plate tectonics theory?
A man named Alfred Wegener first presented the theory of plate tectonics, but had no proof, so other scientists laughed at him. later, Arthur Holmes decided that it wasn't such a laughing matter, due to the theory of convection currents in the mantle. so Alfred Wegener first presented it, but Arthur Holmes proved it. hope this helps.
Why was Alfred wegener theory rejected in the early 1900s?
he had no proof how the continents drifted or what made them drift
How did Alfred wegener's inventions helped us?
It helped us by creating the theory of seafloor spreading which is the proof alfred needed to complete his hypothesis
What made scientists accept Alfred wegener theory years later?
Accumulating data, especially proof of sea floor spreading.
Did Alfred Wegener find any glacier deposits in unusual places?
Yes! He found them very close to the equator, which was very unusual.... just more proof!!!
What proof did they have that Pangaea is real?
There is no direct proof. But there is evidence best explained by Pangaea having existed. This is the case with a lot of science, and looking for proof is not a very productive way to proceed. Proof works well only in mathematics.
Why was Alfred Wegners continental drift theory ignored?
Alfred Wegner's continental drift theory was ignored because he didn't have enough proof to show everyone that tectonic plates were moving. The supercontinent Pangaea sounded like a big fantasy to everyone back then.
What did wegener think happens during continental drift-?
he thought that there was a pangaea, a super continent, and proof was found later of of sea floor spreading and fossils of tropical plants in Antarctica. if u need more info its called Google look it up!
What is proof of theory of plate tectonics developed?
because of pangaea
How do science know pangaea is real?
scientists proof of pangaea is there were fosils of the same animals or dinosaurs in all 7 continents
Where did wegener look for proof that would support his theory of continental drift?
fossila and landforms
What is the theory of is an outgrowth of Alfred Wegener's theory of continental drift?
The problem with continental drift was no mechanism could be found by which the continents could drift through the solid rock of the ocean seafloor. In the 1950s the US Navy found the evidence of alternating polarity magnetic stripes on the ocean seafloor that were symmetrical on opposite sides of the midocean ridges. But this information was kept classified until the late 1970s. When it was declassified and made available to geophysicists it became the proof that showed the continents were not drifting as Wegener proposed, but the earth's crust was divided into plates that dragged the continents along with them as they moved.
