What was Wegener's theory of continental drift?
Wegener theory of continental drift was that in the past the whole world was all joined together and the lands name was Pangaea meaning All lands. However, Wegener could not provide a satisfactory explanation for the force that pushes or pulls the continents apart.
Why did doubters reject Wegener's ideas?
He couldn't explain the force that pushes or pulls the continents.
Why did the people did not believe Alfred Wegener?
One reason the scientific community doubted him was because he wasn't able to come up with an explanation for how the continents were moving, & where the force to move them was coming from.
What is the hypothesis that states that the continents were once one large mass that broke apart?
Pangea. Alfred Wegener proposed the theory of continental drift, that the landmasses of the Earth were connected and slowly drifted apart, in 1912. His justifications for his theory included how the various continents looked like they could fit together and proposed that either centrifugal force of the Earth's rotation or astronomical precession were the forces behind the drift.
What was one question that Alfred wegener could not answer?
One question Alfred Wegener could not answer was the mechanism that caused the movement of continents, as he proposed the theory of continental drift before the discovery of plate tectonics. He could not explain how or why continents would be able to move through solid oceanic crust.
What two forces did Alfred Wegener suggest were responsible for the movement of the continents?
Alfred Wegener suggested that the two forces responsible for the movement of continents were continental drift (the movement of continents across Earth's surface) and sea-floor spreading (the formation of new oceanic crust at mid-ocean ridges).
Which force occurs where earth plate are moving apart?
what
How did Alfred wegener think mountain were formed?
Alfred thought that mountain were formed by two continents smashing together with such force that the land was forced up.
What did Wegener say about how continents move?
Alfred Wegener also came up with a theory to explain continental drift, although it was in error. His theory of continental drift proposed that centrifugal force moved the heavy continents toward the equator as the Earth spun. He thought that inertia, from centrifugal movement combined with tidal drag on the continents (caused by the gravitational pull of the sun and moon) would account for continental drift.I think the sentence in italic and bold is the answer...~anonme~!danah!
What two forces did wegener suggest were responsible for the movement of the contenents?
Wegener proposed two forces for the movement of continents: gravitational pull caused by the Earth's rotation, and the force generated by the mantle convection currents beneath the Earth's crust.
What is the weakness in Wegener's continental drift hypothesis?
A weakness in Wegener's continental drift hypothesis was the lack of a mechanism explaining how the continents moved. Additionally, he was unable to provide evidence supporting the force that would be strong enough to move continents across the Earth's surface. Lastly, Wegener's theory faced skepticism from the scientific community at the time due to a lack of detailed data and observations supporting his idea of continental drift.
What is seafloor spreading that ''helps'' the theory of continental drift?
How seafloor spreading helps to explain the theory of continental drift is that wegener couldn't explain why and waht force caused the continents to move and so seafloor spreading helps to explain the theory of continental drift because it shows the force that made the continents move and that was te only thing that wagener needed to prove his theory of continental drift............thanks
