Which of the following was used in support of the continental drift hypothesis?
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 are the 4 supports for 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.
Which of the following evidence doesn’t support the continental drift theory?
Answer: The theory doesn't consider oceans. Forces like buoyancy, tidal currents and gravity are too weak to be able to move continents.
What are the 5 evidences that support the continental drift theory?
They based their idea of continental drift on several lines of evidence: fit of the continents, paleoclimate indicators, truncated geologic features, and fossils.
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 is the evidence for continental drift quizlet?
Fossils of same creature have been found on different continents that are separated today but were once joined. For example. a 20 cm Mesosaurus reptile could not have swam 3000 miles across and ocean. It's more likely the continents were together and over 40 million years it walked.
What are the evidence in support of the continental drift theory Upsc?
Placer Deposits The widespread distribution of Permo-Carboniferous glacial sediments in South America, Africa, Madagascar, Arabia, India, Antarctica, and Australia was one of the major pieces of evidence for the theory of continental drift.
Why was Wegener’s theory 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 is the hypothesis of continental drift quizlet?
What is the continental drift hypothesis? Proposed by Alfred Wegener, it states that Earth's continents have moved slowly to their current locations. All the continents were once connected as one landmass that broke apart 250 million years ago. This one landmass is called "Pangea," meaning "all land."
What are examples of continental drift?
As the seafloor grows wider, the continents on opposite sides of the ridge move away from each other. The North American and Eurasian tectonic plates, for example, are separated by the Mid-Atlantic Ridge. The two continents are moving away from each other at the rate of about 2.5 centimeters (1 inch) per year.
What evidence supported Wegener’s hypothesis of continental drift quizlet?
The Theory of Continental Drift was proposed by Alfred Wegener in 1912. He used several pieces of evidence to support his theory including fossils, rocks, glacial markings, coal deposits and the fact that the continents fit together like a jigsaw puzzle. .
What evidence did Wegener find for Pangaea quizlet?
Wegener showed that certain types of rocks on the continents would match with others in another continent. What did Wegener realize about the oldest rocks on the Afircan and South American continents? That they were connected together when the continents were arranged to form Pangaea.
What is continental drift hypothesis?
Continental drift is the hypothesis that the Earth's continents have moved over geologic time relative to each other, thus appearing to have "drifted" across the ocean bed.
What is continental drift theory explain with evidence?
The theory of continental drift is most associated with the scientist Alfred Wegener. 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.
Which of the following is not one of the reasons that Wegener’s hypothesis of continental drift wasn’t accepted by the scientific community?
Answer and Explanation: Wegener's idea of continental drift was not accepted by the scientific community because he was unable to explain how the continents moved.
What could Wegener not explain about continental drift?
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 …
Which of the following is a reason why continental drift theory was not accepted at first quizlet?
Most scientists did not accept the theory of continental drift because Wegener could not explain how continents were moving around on Earth's surface.
Why did scientists not accept the continental drift hypothesis quizlet?
Why did scientists not accept the Continental Drift hypothesis? It was based on observations from the southern hemisphere which was unfamiliar to most geologists.
What is continental drift theory?
The theory of continental drift is most associated with the scientist Alfred Wegener. 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.
What causes continental drift quizlet?
a current caused by the rising of heated fluid and sinking of cooled fluid. The earth's crust and upper mantle are made of huge plates slowly drifting because of convection currents in the mantle.
What three evidence supports Wegener’s theory?
The Theory of Continental Drift was proposed by Alfred Wegener in 1912. He used several pieces of evidence to support his theory including fossils, rocks, glacial markings, coal deposits and the fact that the continents fit together like a jigsaw puzzle. .
What are the four pieces of evidence for continental drift quizlet?
List four pieces of evidence for Wegener's hypothesis of continental drift? Continents fit like a puzzle, climate clues, fossil clues, and rock layers or formations.
What evidence supports Wegener’s continental drift hypothesis quizlet?
The Theory of Continental Drift was proposed by Alfred Wegener in 1912. He used several pieces of evidence to support his theory including fossils, rocks, glacial markings, coal deposits and the fact that the continents fit together like a jigsaw puzzle. .
Why was Alfred Wegener’s hypothesis rejected?
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.
Which of the following was missing from Wegener’s hypothesis?
Portrayal of thermal convection as a mechanism. The main issue with Wegener's Continental Drift Theory was he did not have a mechanism behind the drifting of continents.
Why was the continental drift hypothesis rejected?
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 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.
Why did scientists reject Wegener’s theory of continental?
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.
