Why did no one believe Wegener’s theory?
Part of the reason Wegener’s ideas were not initially accepted was the misapprehension that he was suggesting the continents had fit along the current coastline..
Which features were considered evidence of continental drift?
Evidence for continental drift Wegener knew that fossil plants and animals such as mesosaurs, a freshwater reptile found only South America and Africa during the Permian period, could be found on many continents. He also matched up rocks on either side of the Atlantic Ocean like puzzle pieces.
What evidence of climate change on continents supports the theory of continental drift?
The ‘same animal fossils’ found on different continents provide evidence climatic change on continent supporting the theory of ‘continental drift’.
What did the evidence of fossils on opposing continents mean?
Alfred Wegener collected diverse pieces of evidence to support his theory, including geological “fit” and fossil evidence. … This indicates that these continents had to be once joined together because the extensive oceans between these land masses act as a type of barrier for fossil transfer.
Why was Continental Drift rejected?
This idea was quickly rejected by the scientific community primarily because the actual forces generated by the rotation of the earth were calculated to be insufficient to move continents.
Which two pieces of fossils evidence support the idea of continental drift?
The similarities between the Appalachian and the eastern Greenland mountain ranges are evidences for the continental drift hypothesis. Ancient fossils of the same species of extinct plants and animals are found in rocks of the same age but are on continents that are now widely separated (figure 3).
What are 3 pieces of evidence for Pangea?
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 the first evidence of continental drift?
The first truly detailed and comprehensive theory of continental drift was proposed in 1912 by Alfred Wegener, a German meteorologist. Bringing together a large mass of geologic and paleontological data, Wegener postulated that throughout most of geologic time there was only one continent, which he called Pangea.
What is the evidence for Pangea?
Evidence of existence Fossil evidence for Pangaea includes the presence of similar and identical species on continents that are now great distances apart.
What is the best piece of evidence for plate tectonics?
Modern continents hold clues to their distant past. Evidence from fossils, glaciers, and complementary coastlines helps reveal how the plates once fit together. Fossils tell us when and where plants and animals once existed.
What did Earth look like before Pangea?
But before Pangaea, Earth’s landmasses ripped apart and smashed back together to form supercontinents repeatedly. … Just like other supercontinents, the number of detrital zircon grains increased during formation and dropped off during breakup of Rodinia.
What are 6 pieces of evidence that support continental drift?
What are six pieces of evidence for the continental drift theory? Reptile Fossils- dinosaurs couldn’t have swam across a vast ocean. Plant Fossils- all these regions were once connected and had similar climates. Tropical plants found in Arctic- tropical plants can’t grow in cold climates.
Which three continents contain coal fields that provide evidence for continental drift?
The answer is Eurasia, North America, Africa, and South America. Most of the coal fields in the world are located in these countries along with good quality coal fields are found in Africa and South America.
Which sources of evidence did Wegener use to support his theory of continental drift check all that apply?
Wegener’s theory Wegener used geologic, fossil, and glacial evidence from opposite sides of the Atlantic Ocean to support his theory of continental drift. For example, he said that there were geological similarities between the Appalachian Mountains in North America, and the Scottish Highlands.
Which two continents contain fossils of Mesosaurus?
Remains of Mesosaurus, a freshwater crocodile-like reptile that lived during the early Permian (between 286 and 258 million years ago), are found solely in Southern Africa and Eastern South America. It would have been physiologically impossible for Mesosaurus to swim between the continents.
