What Was The Main Reason Wegener’s Continental Drift Hypothesis Was 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?
Why was Wegener’s hypothesis rejected? Because Wegener could not identify the cause of continental drift most geologists rejected his idea. Continental drift was what Wegener invented. Wegener’s hypothesis was rejected from geologists because he couldn’t identify the cause of continental drift.
What was the major problem with Wegener’s theory of continental drift?
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.

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. … Three pieces of evidence scientists found that support the idea of seafloor spreading.
Which statement does not support Wegener’s theory of continental drift?
Wegener’s continental drift hypothesis was not supported by evidence. Wegener’s continental drift hypothesis did not give a plausible explanation for how continents move. Wegener’s continental drift hypothesis did not state that the continents were arranged into a supercontinent many millions of years ago.
What might have caused the continents to move?
The movement of these tectonic plates is likely caused by convection currents in the molten rock in Earth’s mantle below the crust. … The long-term result of plate tectonics is the movement of entire continents over millions of years (Fig.
What causes the 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.
Why was Wegener’s idea a 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 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.
What did Alfred Wegener use as evidence for his theory that the continents were once one giant land mass quizlet?
What evidence did Wegener make use of to develop the theory of continental drift? Similar fossils were found on different continents.
Which of these was used by Alfred Wegener as evidence that Earth’s continental landmasses had drifted apart over time?
How did fossils provide evidence for continental drift? Similar fossils occur on different continents. Because many of these organisms could not have crossed an ocean this provides evidence that the continents were once connected.
Which of the following was a central line of evidence for Wegener’s continental drift hypothesis?
Alfred Wegener in the first three decades of this century and DuToit in the 1920s and 1930s gathered evidence that the continents had moved. They based their idea of continental drift on several lines of evidence: fit of the continents paleoclimate indicators truncated geologic features and fossils.
What was Wegener’s hypothesis about the continents?
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.
Why was Greenland Wegener’s theory important?
What are the 3 main pieces of evidence that support the theory of continental drift?
The evidence for continental drift included the fit of the continents the distribution of ancient fossils rocks and mountain ranges and the locations of ancient climatic zones.
Which statement would best support Wegener’s hypothesis?
The continents we see today are fragments of that supercontinent. To support his theory Wegener pointed to matching rock formations and similar fossils in Brazil and West Africa. In addition South America and Africa looked like they could fit together like puzzle pieces.
Which of the following was not used in support of the continental drift hypothesis?
| Term Wegener’s continental drift hypothesis stated that all the continents once joined together to form… | Definition A single continen |
|---|---|
| Term which of the following was NOT used in support of the continental drift hypothesis> | Definition |
Why was continental drift so controversial during Alfred Wegener’s time what explanation was necessary to support his hypothesis?
What explanation was necessary to support his hypothesis? Continental drift is not easily observable because tectonic plates move very slowly. When Wegener proposed the continental drift hypothesis he was unable to identify a force that could move continents.
What force drive the drifting of the continents?
The energy source for plate tectonics is Earth’s internal heat while the forces moving the plates are the “ridge push” and “slab pull” gravity forces. It was once thought that mantle convection could drive plate motions.
What causes the tectonic plates to move and cause continental drift?
The crust is broken up into giant tectonic plates that ride atop the magma hot melted-rock material that makes up much of the interior of the Earth. Over millions of years the continents drift into new configurations. Convection in the molten rock of Earth’s mantle drives the movement of the plates.
What force caused the movement of the continents from one supercontinent?
Geologists think that movement of the convection currents in the mantle is the major force that causes plate motion. _________________________________________________Convection currents caused the movement of the continents from one supercontinent to their present positions.
What is the continental drift quizlet?
The hypothesis that states that the continents once formed a single landmass broke up and drifted to their present locations. …
Why do continents move quizlet?
Thermal energy generated in the Earth’s core causes the tectonic plates on the Earth’s surface to move. This movement occurs due to convection currents deep in the Earth.
What questions do you have about the theory of continental drift?
1) What are ‘tectonic plates’? 2) What happens at the boundaries between these plates? 3) What are fault lines? 4) What a ect has Continental Drift had on the shape of the earth’s surface?
Who rejected Wegener’s?
What was the response to Wegener’s hypothesis?
The main problem with Wegener’s hypothesis of Continental Drift was the lack of a mechanism. He did not have an explanation for how the continents moved. His attempt to explain it using tides only made things worse. But both Galileo and Darwin had serious flaws in their theories when they were first presented.
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. … Wegener suggested the thick continents moved through the thinner ocean crust.
What was Alfred Wegener’s continental drift hypothesis 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.”
Why was Alfred Wegener’s hypothesis of continental drift not well accepted by most of the scientific community quizlet?
