When was Wegener’s idea of continental drift rejected?
Geologists roundly denounced Wegener's continental drift theory after he published the details in a 1915 book called "The Origin of Continents and Oceans (opens in new tab)." Part of the opposition was because Wegener didn't have a good model to explain how the continents moved, something scientists later explained …
Why was Alfred Wegener’s theory of continental drift rejected quizlet?
Wegener's hypothesis was rejected from geologists because he couldn't identify the cause of continental drift.
What is the continental drift idea who suggested it and why was it rejected?
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.
Who rejected continental drift theory?
The idea was moonshine, I was informed." As late as 1953—just five years before Carey introduced the theory of plate tectonics—the theory of continental drift was rejected by the physicist Scheidegger on the following grounds.
When was Wegener’s theory accepted?
Wegener first presented his idea of continental drift in 1912, but it was widely ridiculed and soon, mostly, forgotten. Wegener never lived to see his theory accepted—he died at the age of 50 while on an expedition in Greenland. Only decades later, in the 1960s, did the idea of continental drift resurface.
Why did most scientists reject Wegener’s theory for nearly a half century *?
Why did most scientists reject Wegener's theory for nearly a half century? Most scientists rejected Wegener's theory because he could not explain the force that pushes or pulls the continents.
Was Alfred Wegener’s theory accepted?

Wegener never lived to see his theory accepted—he died at the age of 50 while on an expedition in Greenland. Only decades later, in the 1960s, did the idea of continental drift resurface.
Is Alfred Wegener’s theory true?
Wegener published his theory in full in 1915, but his contemporaries mostly found it implausible. By 1930 it had been rejected by most geologists, and it sank into obscurity for the next few decades.
What is Wegener’s theory of continental drift?
Alfred Wegener proposed that the continents were once united into a single supercontinent named Pangaea, meaning all earth in ancient Greek. He suggested that Pangaea broke up long ago and that the continents then moved to their current positions. He called his hypothesis continental drift.
Why did most scientists not agree with the continental drift theory quizlet?
Why did most scientists reject Wegener's theory for nearly a half century? Most scientists rejected Wegener's theory because he could not explain the force that pushes or pulls the continents.
When was continental drift accepted?
The first truly detailed and comprehensive theory of continental drift was proposed in 1912 by Alfred Wegener, a German meteorologist. Bringing together a large mass of geologic and paleontological data, Wegener postulated that throughout most of geologic time there was only one continent, which he called Pangea.
What happened to Alfred Wegener?
Wegener died in Greenland in November 1930 while returning from an expedition to bring food to a group of researchers camped in the middle of an icecap.
Which of the following was not used in support of the continental drift hypothesis?
Explanation. Wegener did not use paleomagnetism to support his continental drift hypothesis.
What were the two major flaws of Wegener’s theory of continental drift?
Alfred Wegener proposed two different mechanisms for continental drift. One was based on the centrifugal force caused by the rotation of the earth and another a 'tidal argument' based on the tidal attraction of the sun and the moon. These explanations could easily be proven inadequate.
What was the problem with continental drift?
The problem that was used to reject Continental Drift is that the theory had no mechanism or explanation for what could cause the movement of the massive continents.
Which of the following contradicts the continental drift theory?
The theory of continental drift contradicted the prevailing theory of geosynclines. The geosyncline theory was used to explain how continents, sedimentary layers, and mountains were formed. The scientific community was invested in the geosyncline theory so rejected the Continental drift theory.
What was missing from Alfred Wegener’s hypothesis?
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.
What was Wegener’s evidence for continental drift?
Wegener used fossil evidence to support his continental drift hypothesis. The fossils of these organisms are found on lands that are now far apart. Grooves and rock deposits left by ancient glaciers are found today on different continents very close to the equator.
What did Wegener wrong?
We now know that Wegener's theory was wrong in one major point: continents do not plow through the ocean floor.
What was the major weakness of Wegener’s theory?
Because he could not explain a mechanism that would cause the Earths' crustal plates to shift around, his idea was dismissed at the time. He also had rates of movements for his continents that seemed very unlikely – too high.
What disproved Wegener’s theory?
Essentially, Wegener's proposal ( the theory of continental drift ) was rejected because (i) established experts firmly believed in another theory (that the continents and oceans were fixed in position), and (ii) Wegener did not provide a reasonable mechanism which would enable continents to move in the manner he …
