Alfred Wegener's hypothesis of continental drift lacked a convincing mechanism to explain how continents could move across the Earth's surface. He proposed that continents plowed through the oceanic crust, but this idea was not supported by any physical evidence. It wasn't until the development of plate tectonics in the mid-20th century, which provided the concept of tectonic plates and their movement due to convection currents in the mantle, that Wegener's ideas gained broader acceptance.
What else can I help you with?
What evidence did wegner have to support his hypothisis?
Alfred Wegener supported his hypothesis of continental drift with several key pieces of evidence. He noted the jigsaw-like fit of the continents, particularly South America and Africa, suggesting they were once joined. Additionally, he cited fossil evidence, such as the identical Mesosaurus found in both South America and Africa, and geological similarities, like matching mountain ranges and rock formations across continents. Lastly, he referenced climatic evidence, including coal deposits in polar regions and glacial deposits in currently warm areas, indicating that continents had shifted over time.
How did advances in technology change wegner's hypothesis?
The way the advances in technology are changing Wegener's hypothesis is because we can now collect information and data on the Tectonic Plates. Without the technology we have now, we would know hardly anything about why the plates.
Why was wegener's theory not accepted by all scientists?
Wegner's theory was not accept because he didn't have much evidence to support his theory with and scientists thought that there might have been a land bridge between the continents. Another reason to why his theory was rejected was that he was a foreigner, by that; the scientists didn't really take him seriously.
Why was wegner's theory and evidence not a well accepted at first?
stop cheating i know it is on a science worksheet if you truly dont know then pay attention in class you idiots dont be so lazy stupid as
Did Alfred Wegner have children?
Yes, three.
One kind of evidence that supports wegner's hypothesis is that?
Fossil evidence showing similar plant and animal species in regions that are now widely separated provides support for Wegner's hypothesis of continental drift. This suggests that the continents were once connected in a single landmass.
Does fossil evidence support wegner's theory?
yes
What was Alfred wegners hypothesis about Pangaea?
Alfred Wegner's hypothesis about Pangea was that it is one whole big continent.
Why did most scientists reject Wegner theory for nearly a half century?
They rejected Wenger's theory for half a century because he didn't have the evidence to prove his theory No, He did have evidence to prove his theory, they just did not believe him- TheSystem because of their lack of knowledge of the Earth He actually had evidence, but it was actually because the hypothesis interferred with their own hypothesis about how mountains form.
What type of information Alfred wegner use on his theory?
He used evidence from landform, climate, and fossils to support his theory of the continental drift.
Why did scientists reject wegners theory 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.
How did wegner use climate evidence to support his evidence?
In Africa there are scratch marks that could only have been caused by glaciers but Africa is by a hot place by the equate so once it was colder there
What are 2 main pieces of evidence that prove wegner's theory?
Two main pieces of evidence that support Wegner's theory of continental drift are the fit of the continents' coastlines, indicating they were once connected, and the distribution of similar fossils and rock formations across separate continents, suggesting a shared geological history.
Summarize the evidence that supports wegner's hypothesis?
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.
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 are 4 pieces of evidence4 alferd wegner used to support this theory?
Four pieces of evidence used by Alfred Wegener to support his theory of continental drift were the fit of the continents, matching geological formations across continents, similar fossil distributions, and glacial evidence in tropical regions.
How did wegner use climate evidence to support his hypothosis?
In Africa there are scratch marks that could only have been caused by glaciers but Africa is by a hot place by the equate so once it was colder there
