What else can I help you with?
Does the case of mesosaurus support wegeners theory of continental drift?
yes it does.
What roole did the fossil glossopteris play in wegeners hypothisis?
Glossopteris, a seed fern found in fossil records across several continents, played a crucial role in Alfred Wegener's hypothesis of continental drift. Its widespread distribution in now-separated landmasses, such as South America, Africa, Antarctica, and Australia, provided evidence that these continents were once joined. The presence of Glossopteris in these diverse locations suggested that they must have been connected in a single landmass, which Wegener named Gondwana. This fossil evidence supported his argument for the movement of continents over geological time.
The scientist of wegeners should have rejected his idea?
no because then they would know least about the world
Wegeners hypothesis of continental drift was replaced in 1967 by which theory that supported his idea continents move?
plate tectonics
What was the reason wegeners continental drift hypothesis was rejected?
His evidence was incorrect.
What is wegeners hypothesis for continental drift?
Wegener's hypothesis for continental drift, proposed in the early 20th century, suggests that continents were once part of a single supercontinent called Pangaea, which gradually broke apart and drifted to their current positions. He based his hypothesis on evidence such as the fit of continental coastlines, similar geological features across continents, and fossil correlations. Despite presenting compelling evidence, Wegener's theory was initially met with skepticism due to the lack of a mechanism to explain how continents could move. It wasn't until the development of the theory of plate tectonics that his ideas gained widespread acceptance.
What were the flaws in wegeners hypothesis that made people reject it?
Wegener's hypothesis of continental drift was largely rejected due to a lack of a plausible mechanism to explain how continents could move across the Earth's surface. He proposed that continents plowed through the oceanic crust, which seemed implausible to many scientists. Additionally, his ideas conflicted with the prevailing theories of the time, such as land bridges and static continents. The discovery of plate tectonics in the 1960s eventually provided the necessary mechanisms for continental movement, validating Wegener's ideas long after their initial rejection.
Wegeners hypothesis of continental drift was finally confirmed by?
evidence supporting the idea of sea-floor spreading.
What was the main reason wegeners continental drift was rejected?
He could not provide a wholly acceptable explanation for the movement of the continents.
How did others feel about wegeners hypothesis?
Alfred Wegener's hypothesis of continental drift was met with significant skepticism and resistance from many in the scientific community during his time. Critics argued that he lacked a plausible mechanism to explain how continents could move, leading to widespread dismissal of his ideas. However, over time, as more evidence emerged and the theory of plate tectonics developed, Wegener's hypothesis gained acceptance and is now recognized as a foundational concept in geology.
What was the fatal weakness in wegeners theory?
One of the fatal weaknesses in Wegener's theory of continental drift was the lack of a plausible mechanism to explain how continents could move through the solid rock of Earth's mantle. Additionally, Wegener was unable to adequately explain what forces could be responsible for moving the continents.
How did the discovery of Glossopteris support Wegeners continental drift hypothesis?
Because identical fossils were found on two continents far apart, it suggested that at one time the two landmasses were joined together. In other cases of lands separated by far less distance, plants did not propagate across the divide.
Why was the wegeners hypothesis o the continental drift not widely accepted at the time it was proposed?
Although it seemed to make a lot of sense, there was no known proof of HOW the continents would drift. It wasn't until years later that we gained knowledge of plate tectonics, which bolstered Wegener's hypothesis.
What was the weakness of wegeners proposal of continental drift?
One weakness of Wegener's proposal of continental drift was the lack of a mechanism to explain how continents could move. Additionally, Wegener's theory was not widely accepted at the time due to insufficient supporting evidence and the reluctance of the scientific community to accept such a radical idea.
Why was wegeners theory of continental drift?
While geological research during the sixties had shed new light into the theory, it was J. Tuzo Wilson's proposal of a mechanism for continental drift what led to widespread acceptance of the theory. Proposing a feasible mechanism was something Wegener himself had failed to do, he had only proposed some evidence (complementary Coastlines and fossil distributions across continents.) and falsified mechanisms (like Earth's centrifugal pseudoforce).
