Alfred Wegener proposed his theory of continental drift based on three main pieces of evidence: first, the jigsaw-like fit of continental Coastlines, particularly South America and Africa; second, the presence of similar fossils, such as Mesosaurus and Glossopteris, found on widely separated continents; and third, geological similarities, including matching rock formations and mountain ranges across continents. These observations suggested that continents were once connected and have since drifted apart over time.
What else can I help you with?
What evidence did wegener have to prove his hypothesis?
Alfred Wegener used several pieces of evidence to support his theory of continental drift, including the fit of continents like South America and Africa, similarities in rock formations and fossils across continents, and the matching of ancient climate indicators like glaciation patterns. Despite facing initial skepticism, Wegener's evidence paved the way for the development of the theory of plate tectonics.
What 3 pieces of evidence did wegener cite to propose his theoy?
Alfred Wegener proposed his theory of continental drift by citing three main pieces of evidence: first, the jigsaw-like fit of the continents, particularly South America and Africa; second, the distribution of similar fossils across widely separated continents, such as the Mesosaurus found in both South America and Africa; and third, geological similarities, including matching rock formations and mountain ranges found on different continents. These observations suggested that the continents were once joined together in a supercontinent before drifting apart.
Which one of the following was NOT presented by Alfred wegener as evidence of continental drift?
Alfred Wegener presented several pieces of evidence for continental drift, including the fit of the continents, fossil correlations, and geological similarities across continents. However, he did not present the concept of plate tectonics, as this theory was developed later to explain the mechanisms behind continental drift. Therefore, any evidence specifically related to plate tectonics would not have been part of Wegener's original arguments.
What evidence did Alfred wegener have to support his theory?
Alfred Wegener's theory of continental drift was supported by several lines of evidence, including the matching coastlines of different continents, similarities in rock formations and mountain ranges across continents, and the distribution of fossils of similar species on different continents. He also observed the fit of the continents like pieces of a jigsaw puzzle and the presence of ancient glacial deposits in regions that are now at different latitudes.
What was the evidence Alfred wegener used to support his idea?
Alfred Wegener supported his theory of continental drift with several pieces of evidence. He noted the complementary shapes of continents, particularly how South America and Africa fit together like puzzle pieces. Additionally, he pointed to fossil evidence, such as identical species of plants and animals found on widely separated continents, and geological similarities, including matching rock formations and mountain ranges across continents. Lastly, he highlighted paleoclimatic evidence, such as glacial deposits in now-tropical regions, suggesting that continents had once been positioned differently.
What was Alfred wegener's evidence for his theory on continental drift?
Alfred Wegener's evidence for continental drift included the fit of the continents like puzzle pieces, the distribution of plant and animal fossils across continents, similarities in rock formations and mountain ranges, and evidence of past glaciations in regions that are now tropical. These observations led him to propose the theory of Pangea and the idea that continents were once joined together in a supercontinent.
What is one piece of evidence that caused wegener to think that continents moved?
One piece of evidence that led Wegener to propose the theory of continental drift was the observation that the coastlines of Africa and South America appeared to fit together like puzzle pieces. This suggested that the continents were once joined together and had subsequently drifted apart.
What evidence did Alfred wanger use to support his theory of contnetal drift?
Alfred Wegener used several lines of evidence to support his theory of continental drift. This included the fit of the continents like a jigsaw puzzle, similarities in rock formations and mountain ranges across different continents, matching fossils on separate continents, and paleoclimatic evidence such as glacial striations in tropical regions. These pieces of evidence led Wegener to propose the theory of continental drift in the early 20th century.
Did Wegener used glacial striations to help build the theory of plate tectonincs?
Yes, Wegener did use evidence of glacial striations to support his theory of continental drift. He observed that matching glacial striations on continents separated by oceans suggested they were once connected and had moved apart. This was one of the pieces of evidence Wegener used to develop his theory of plate tectonics.
What three pieces of evidence for Wegener's theory came from the sea floor?
seafloor spreading, age of the sea floor and ocean trenches.
What pieces of evidence Alfred wegener used to support his theory?
The pieces of evidence Alfred Wegener used to support his theory about continental drift were; Puzzle Fit, Fossil evidence from animals that were once on the same continent, geologic evidence like mountain chains that were connected and now split apart, and ice sheets. Thank you for reading this article and I hoped it answered your question!
What evidence of land feautures did Alfred wegener use?
Alfred Wegener used various pieces of evidence to support his theory of continental drift, including the fit of the continents, rock and fossil similarities across continents, glacial evidence, and similar geological features on different continents.
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.
Which one of the following pieces of evidence did Wegener use to support his theory of continental drift?
the age of the rocks in the sea floor is all the same
What were the 3 types of evidence the Alfred Wegener used to support his theory of Continental Drift?
Alfred Wegener used fossil evidence, geological evidence, and paleoclimatic evidence to support his theory of Continental Drift. Fossils of the same species found on different continents, similar rock formations and mountain ranges across continents, and matching ancient climate patterns were key pieces of evidence that he presented.
What are 4 pieces of evidence4 alferd wegner used to support this theory?
Four pieces of evidence used by Alfred Wegener to support his theory of continental drift were the fit of the continents, matching geological formations across continents, similar fossil distributions, and glacial evidence in tropical regions.
