What did Wegener argue?
He argued against the claim that earlier land bridges between the continents had sunk. He also disputed the theory that mountains formed like wrinkles on the skin of a drying apple, claiming instead that mountains formed when the edges of drifting continents crumpled and folded.
What was the main objection to Wegener’s hypothesis?
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 problem did Wegener’s hypothesis have?
The Problem with the Hypothesis To his colleagues, his greatest problem was that he had no plausible mechanism for how the continents could move through the oceans. Based on his polar experiences, Wegener suggested that the continents were like icebreaking ships plowing through ice sheets.
What evidence supported Wegener’s hypothesis of continental drift?
The four pieces of evidence for the continental drift include continents fitting together like a puzzle, scattering ancient fossils, rocks, mountain ranges, and the old climatic zones’ locations.
What is the continental drift hypothesis?
Wegener’s continental drift theory introduced the idea of moving continents to geoscience. He proposed that Earth (opens in new tab) must have once been a single supercontinent before breaking up to form several different continents.
What was one of the main objection to the continental drift theory?
One of the main objections to the continental drift hypothesis was the inability of its supporters to provide an acceptable mechanism for the movement of continents.
Why was Alfred Wegener’s hypothesis for continental drift rejected?
Wegener’s inability to provide an adequate explanation of the forces responsible for continental drift and the prevailing belief that the earth was solid and immovable resulted in the scientific dismissal of his theories.
What was Wegener’s hypothesis called?
In the early 20th century, Wegener published a paper explaining his theory that the continental landmasses were “drifting” across the Earth, sometimes plowing through oceans and into each other. He called this movement continental drift.
What was one of the main objection to the continental drift theory Brainly?
“There’s an irony that the key objection to continent drift was that there is no mechanism, and plate tectonics was accepted without a mechanism,” to move the continents, Henry Frankel (1944–2019), an emeritus professor at the University of Missouri-Kansas City and author of the four volume “The Continental Drift …
Why was Alfred Wegener’s hypothesis of continental drift rejected?
Which of the following is one objection of critics about Wegener’s continental drift theory?
One of the main objections to the continental drift hypothesis was its inability to provide an acceptable mechanism for the movement of continents.
What was the main reason Wegener’s continental drift hypothesis was rejected quizlet?
Wegener’s hypothesis was rejected from geologists because he couldn’t identify the cause of continental drift.
What kind of evidence that supports Wegener’s hypothesis is that?
fossil evidence
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.
Which statement is supported by the theory of continental drift?
Which statement is supported by the Theory of Continental Drift? Present-day continents of South America and Africa once fit together like a jigsaw puzzle.
