Why do you think people didn't believe continental drift?
If you ask me it's because they wer a bunch of arogant "scientists" who didn't have a clue what they were talking about and hated being wrong. Just like with Galileo. They could have been scarred to accept things like that. I don't believe in it though... :) De Nada
How long was it before new evidence emerged to support wegeners theory of the continental drift?
New evidence supporting Alfred Wegener's theory of continental drift began to emerge in the late 1940s and early 1950s, approximately 30 years after he first proposed the theory in 1912. The development of plate tectonics, particularly the discovery of seafloor spreading and paleomagnetism, provided crucial evidence that validated Wegener's ideas. This shift in understanding revolutionized geosciences and established a comprehensive framework for explaining the movement of continents.
Why did Wagener's theory of continental drift not accepted?
Alfred Wegener's theory of continental drift was not initially accepted because he lacked a mechanism to explain how continents could move. Additionally, his evidence was considered insufficient and geologists at that time did not believe that continents could drift over time. It was not until the theory of plate tectonics was developed in the 1960s that Wegener's ideas gained widespread acceptance.
Key ideas of the Theory of Continental Drift?
The continental drift theory is the theory that once all of the continents were joined in a super-continent, which scientists call Pangaea. Over a vast period of time, the continents drifted apart to their current locations.
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.

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 two ways is the plate tectonic theory different from the ideas of the continental drift?
The plate tectonic theory expands on the idea of continental drift by incorporating the movement of the Earth's lithosphere into rigid plates. This theory also explains how these plates interact at their boundaries, causing phenomena like earthquakes and volcanic activity. In contrast, continental drift primarily focused on the movement of continents across the Earth's surface without explaining the mechanism behind it.
Why did scientists in 1915 not accept wegeners idea of continental drift?
Scientists in 1915 did not accept Alfred Wegener's idea of continental drift because he lacked a plausible mechanism for how the continents could move. Additionally, Wegener's ideas were seen as radical and went against the prevailing scientific beliefs of the time, so there was resistance to accepting his theory without more concrete evidence. The technology available at the time also did not provide the necessary tools to support Wegener's hypothesis.
How do physical properties of the asthenosphere support the ideas of continental drift and sea floor spreading?
The physical properties of the asthenosphere, such as its semi-fluid state and ability to flow, support the ideas of continental drift and seafloor spreading because they allow the lithospheric plates to move and interact with each other. The asthenosphere acts as a lubricating layer that enables the movement of continents and the creation of new oceanic crust at mid-ocean ridges. This movement is critical in the processes of continental drift and seafloor spreading.
What scientist proposed the first formal theory of continental drift?
Continental Drift was put forward by Alfred Wegener.(1880-1930). One piece of evidence on which he based his ideas was the similarity of shapes of the South American and African coastlines. Another was the fact that the same types of fossil are found in both places.
