Wegner believed that the force causing continental drift was the movement of the continents through the Earth's crust, driven by the gravitational forces associated with the rotation of the Earth. This movement was theorized to be a result of the continents floating on the denser, underlying mantle layer.

Why was Alfred Wegners continental drift theory ignored?
Wegner's continental drift theory was initially ignored because he lacked a plausible mechanism to explain how continents could move. Additionally, Wegner was a meteorologist, not a geologist, which led to skepticism from the geological community. It wasn't until later when the theory of plate tectonics provided a mechanism for continental drift that Wegner's ideas gained acceptance.
Do scientists believe that continental drift is real?
Yes. They believe that the shifting of the tectonic plates under the earth caused it.
What was one of the main objections to Wegner's continental drift hypothesis?
One main objection to Wegner's continental drift hypothesis was the lack of a plausible mechanism to explain how continents could move through solid oceanic crust. At that time, the idea of continental drift contradicted prevailing scientific beliefs about the rigidity of the Earth's crust.
What was used to by Wegner to establish continental drift?
Wegner used evidence from fossil distributions, rock formations, and the fit of continents like puzzle pieces to support his theory of continental drift. He also noted similarities in plant and animal species found on different continents, suggesting they were once connected.
What information did Wegner need to strengthen his argument?
Wegner needed evidence of a mechanism by which continents could move, data supporting the idea of past and present continental positions, geological similarities between continents, and paleoclimatic evidence to strengthen his argument for continental drift.
33 What was the name of the floral fossils Wegener used for the idea of continental drift?
The name of the floral fossils Wegner used for the idea of continental drift was glossopteris. Alfred Wegner used the continental drift as a way to explain the continental shapes.
Who found the theory of continental drift?
Alfred Wegner
Why did scientists argue against Wegners continental drift hypothesis?
Because wegner didnt have proof to show what caused mountains.
Who are the scientists who proposed the theory of continental drift?
alfred wegner
Who is the German scientist connected with continental drift?
Alfred Wegner
When was the continental drift theory established?
Alfred Wegner publicized his theory in 1912.
How many years did wegner figure out about continental drift?
I think about 2 years
Who found the continental drift?
Alfred Wegner originally thought of the continental drift theory, but he wasn't believed when he presented it. After his death (of course) the theory was proved.
What couldn't Wegner identify about continental drift?
he couldn't figure out what was causing it, and he didnt have proof.
Who was the first scientist who first came up with concept of continental drift?
Alfred Wegner was the first person to come up with continental drift

Does the process of continental drift explain why Pangaea no longer exists?
Yes, the process of continental drift explains why Pangaea no longer exists. The movement of tectonic plates over millions of years caused Pangaea to break apart, leading to the formation of the continents as we know them today.
