What evidence did Wegener use to support his theory about Pangaea and why was it rejected?
Alfred Wegener supported his theory of Pangaea with evidence such as the fit of continental Coastlines, fossil similarities across continents, and geological formations that matched across oceans. He also noted climatic evidence, like glacial deposits found in now-tropical regions. However, his theory was rejected primarily because he could not provide a convincing mechanism for how continents could move, leading many scientists to favor alternative explanations for geological phenomena at the time.

What evidence did Alfred wegener use to support his theory of the breakup of Pangaea?
Alfred Wegener used evidence such as the apparent fit of the continents, similarities in rock formations and mountain ranges across continents, and the distribution of fossils of identical species in continents that are now separated by vast oceans to support his theory of the breakup of Pangaea. He also cited geological and paleontological evidence from different continents that suggested they were once connected.
Why was the hypothesis of continental drift rejected when it was proposed by wegener?
Wegener's hypothesis of continental drift was rejected because he lacked a plausible mechanism to explain how the continents moved. Additionally, the scientific community at the time did not have sufficient evidence to support the idea of continents drifting. It wasn't until the theory of plate tectonics emerged later, providing a mechanism and supporting evidence, that continental drift became widely accepted.
Is it true that Alfred wegner provided evidence from landforms and climate in support of his theory of the shrinking earth?
No, Alfred Wegener provided evidence from continental drift and fossil distribution to support his theory of plate tectonics, not a shrinking Earth. Wegener's theory suggested that the continents were once connected in a single landmass (Pangaea) and drifted apart over time due to the movement of tectonic plates.
How did Wagner use fossil evidence to support his theory for Pangaea?
Alfred Wegener used fossil evidence to support his theory of Pangaea by demonstrating that identical fossil species, such as the freshwater reptile Mesosaurus and the seed fern Glossopteris, were found on continents now widely separated by oceans. This distribution suggested that these continents were once joined, allowing species to inhabit a continuous landmass. Additionally, he highlighted similarities in fossilized flora and fauna across continents, indicating a shared biological history that could only be explained by the existence of Pangaea. This fossil evidence bolstered his argument for continental drift, which was a key component of the Pangaea hypothesis.
True or false wegener knew that continental drift explained fossils of tropical plants?
True. Alfred Wegener, the scientist who proposed the theory of continental drift, used the distribution of fossils of tropical plants across continents as evidence to support his idea that the continents were once connected. This was one of the key pieces of evidence Wegener used to support his theory.
How did Pangaea existed during wegener's time?
Pangaea existed during Wegener's time because he proposed the theory of continental drift, suggesting that all the continents were once part of a single landmass that later broke apart. Wegener used evidence such as the fit of the continents, matching rock formations, and similar fossils found on separate continents to support his theory of Pangaea.
What evidence did Alfred wegener use to support his theory of the breakup of Pangaea?
Alfred Wegener used evidence such as the apparent fit of the continents, similarities in rock formations and mountain ranges across continents, and the distribution of fossils of identical species in continents that are now separated by vast oceans to support his theory of the breakup of Pangaea. He also cited geological and paleontological evidence from different continents that suggested they were once connected.
Did Alfred Wegener name a giant landmass Pangaea?
Yes, Alfred Wegener proposed the theory of the supercontinent Pangaea in the early 20th century. The name Pangaea is derived from Ancient Greek, meaning "all lands." Wegener gathered evidence to support the idea that the Earth's continents were once joined into a single landmass before breaking apart and drifting to their current positions.
What evidence did alfred wegener find for pangaea?
Alfred Wegener found several lines of evidence to support the theory of Pangaea, including the fit of the continents, similar rock formations and mountain ranges across continents, matching fossil remains on different continents, and similar climates and glacial deposits in areas that are now far apart.
What kind of tools did Alfred Wegener use to theorize Pangaea?
Alfred Wegener used evidence from the fit of continents, similarities in rock types and structures, fossil evidence, and ancient climate data to develop his theory of Pangaea. He also considered the distribution of plant and animal species across continents to support his idea of continental drift.
What evidence did alfred wegener have for pangea?
Alfred Wegener had several lines of evidence to support his idea of Pangaea, including the fit of the continents, similarities in rock formations and fossils across continents, and the presence of past glacial evidence in regions that are now separated by large distances. Additionally, Wegener noted similarities in climate and geological features that suggested the continents were once connected.
Is it true that Alfred wegener provided evidence from landforms fossils and climate to support his theory of the shrinking earth?
No, Alfred Wegener proposed the theory of continental drift, not a shrinking earth. He used evidence from matching coastlines, fossils, rock types, and climate to support his idea that the continents were once joined in a single supercontinent called Pangaea.
What are the three things Alfred Wegener used to prove his theory about pangaea?
Alfred Wegener used evidence from fossil records, similarities in rock formations across continents, and matching geological features as evidence to support his theory of Pangaea. These observations led him to propose the idea of continental drift, suggesting that the continents were once joined together as a single landmass.
Why was the hypothesis of continental drift rejected when it was proposed by wegener?
Wegener's hypothesis of continental drift was rejected because he lacked a plausible mechanism to explain how the continents moved. Additionally, the scientific community at the time did not have sufficient evidence to support the idea of continents drifting. It wasn't until the theory of plate tectonics emerged later, providing a mechanism and supporting evidence, that continental drift became widely accepted.
How did Wegener use four type of evidence to help support his hypothesis of continental drift?
Alfred Wegener used fossil evidence, geological evidence, paleoclimatic evidence, and the fit of continental coastlines to support his theory of continental drift. By comparing fossils, rock formations, climate patterns, and the alignment of continents like puzzle pieces, Wegener proposed that the continents were once connected in a single supercontinent called Pangaea that drifted apart over time.
Why scientists rejected wegener's hypothesis of continental drift?
Scientist rejected Wegners hypothesis of continental drift at first because he did not have enogh evidence to support his theory. He failed to provide a suitable mechanism that could cause the continents to move.
Which type of evidence was not used by Alfred wegener to support his continental hypothesis?
Which type of evidence was NOT used by Alfred Wegener to support his continental drift hypothesis human remains
