Why was Wegener's hypothesis rejected at first? The main reason that Wegener's hypothesis was not accepted was because he suggested no mechanism for moving the continents. He thought the force of Earth's spin was sufficient to cause continents to move, but geologists knew that rocks are too strong for this to be true.

Why did Wegener's theory of Pangaea fail?
He believed that Pangaea was intact until the late Carboniferous period, about 300 million years ago, when it began to break up and drift apart. However, Wegener's hypothesis lacked a geological mechanism to explain how the continents could drift across the earths surface as he proposed. Additionally, why was Pangaea not accepted?
What is Wegener's theory of the origin of the oceans?
His book, "The Origin of Continents and Oceans," was published in 1912. Other scientists at the time had observed the similarities in fossils in South America and Africa. However, many embraced the idea that these were the result of a land bridge between the two continents. In addition, Wegener's explanation for continental drift was weak.
Why was the theory of continental drift rejected at the time?
It simply was not acceptable to suggest that the continents were somehow plowing through the ocean floor. Without an explanation of how continental drift was possible, it had to be rejected. It wasn’t until seafloor spreading was discovered by Harry Hess that an explanation of the force behind it was available.
Why did Alfred Wegener reject the theory of continental drift?
Alfred Wegener's contemporaries rejected his theory of continental drift because it challenged many established scientific theories at the time, and he lacked a compelling explanation for the cause of continental drift.
What did Wegener believe about continental drift?
Wegener believed that continental drift was the result of centrifugal force and tidal attraction, but the scientific community found the argument weak. Wegener was a German scientist who was one of the first academics to suggest the theory of continental drift. He believed that the Earth once consisted of a single supercontinent called "Pangaea," ...
What caused the continent to drift apart?
He argued that Pangaea was originally located near the south pole and that centrifugal force and tidal pull caused the continent to break up and drift apart. Scientists quickly rejected this explanation, stating that these two forces were not strong enough to cause continental drift.
Why did Wegener not accept his ideas?
Part of the reason Wegener's ideas were not initially accepted was the misapprehension that he was suggesting the continents had fit along the current coastline.”
What did Alfred Wegener study?
Alfred Wegener was mainly a meteorologist and was very interested in studying climate. He traveled all over making many observations during his studies and looking at maps he noticed at first that the obvious shapes of the continents were kind of like pieces of a jigsaw puzzle. He was also interested in geology and geophysics and studied the fossil plants and rocks that occur on the opposing boundaries of the continents as they fit together. They actually matched to a high degree on either
What is Wegener's theory of continental drift?
Wegener's theory of continental drift was kind of a rough draft of the currently accepted theory of plate tectonics. It wasn’t accepted at first, but the more geologists learned, the more the continental drift/plate tectonics idea developed. And it became believable.
Did Alfred Wegener prove continental drift?
Popular presentations often suggest that Alfred Wegener proved continental drift, but hidebound scientists were shamefully slow to accept it. Wegener did indeed do excellent scientific work, but the history is more complicated than this simple tale of the lone iconoclast battling the dogmatic establishment. Also, many more scientists contributed, both before and after Wegener.
Where are the rejection regions in the distribution of the test statistic located?
The Rejection Regions in the distribution of the Test Statistic are located in the Tail Areas, where the Probability reduces towards the tail. The 5% (0.05) rejection region includes the 1% (0.01) area of the tail. Plotting it on a piece of paper will clarify this.
Who came up with the idea of tectonic plates?
Alfred Wegener was a scientist who was not a geologist who came up with the idea of tectonic plates. Because he was not a geologist and his idea contradicted the current thinking among geologists, he was mocked and dismissed. Once the previous generation of geologists was dead, and the idea was revived, but by then poor Alfred was dead also.
Was Wegener a geologist?
First, Wegener was an astronomer, meterologisy and climatologist, not a geologist.
Why was Wegener's hypothesis not accepted?
The main reason that Wegener's hypothesis was not accepted was because he suggested no mechanism for moving the continents. He thought the force of Earth's spin was sufficient to cause continents to move, but geologists knew that rocks are too strong for this to be true.
What was Wegener's greatest problem?
The greatest problem facing Wegener was the lack of direct evidence for the movements of continents (no GPS at the time!) and no mechanism was known to be powerful enough to move entire continents.
Why did the scientists oppose Wegener's theory of continental drift?
Part of the opposition was because Wegener didn't have a good model to explain how the continents moved apart.
Why was the idea of rotation rejected by the scientific community?
This idea was quickly rejected by the scientific community primarily because the actual forces generated by the rotation of the earth were calculated to be insufficient to move continents.
Who first suggested that continents might have drifted?
The speculation that continents might have 'drifted' was first put forward by Abraham Ortelius in 1596. The concept was independently and more fully developed by Alfred Wegener in 1912, but his theory was rejected by many for lack of any motive mechanism.
Why was continental drift rejected?
However, his theory was rejected because of two reasons: The first reason was that his theory of continental drift was just too weak for most geologists to accept. Even though he believed the supercontinent that broke up into different continents moved, he did not have a clear explanation to how the continents moved.
Who suggested that the Earth was a one big supercontinent called Pangaea?
This is a great question. Alfred Wegener was a German scientist who suggested the theory of continental drift. His theory suggested that Earth was a one big supercontinent called Pangaea. The Pangaea broke up and drifted to form all those continents you see today.
