What evidence led to the development of the continental drift hypothesis?
The four pieces of evidence for the continental drift include continents fitting together like a puzzle, scattering ancient fossils, rocks, mountain ranges, and the old climatic zones' locations.
How did Alfred Wegener develop his theory of continental drift?
Wegener noticed the similarity in the coastlines of eastern South America and western Africa and speculated that those lands had once formed a supercontinent, Pangaea, which had split and slowly moved many miles apart over geologic time.
What observations led to the proposal of continental drift?
What observations led to the proposal of continental drift? The matching coastlines of continents of opposite sides of the Atlantic Ocean suggest that the continents were once joined.
What did Wegener need to do to explore the question and make it into a hypothesis?
What did he need to do to explore the question and make it into a reasonable hypothesis? Find evidence. How did Wegener use fossil evidence to support his hypothesis? He realized fossils were on 2 different sides of the Atlantic, but thought that they were too far apart.
Which data was used to develop the hypothesis of continental drift?
The four pieces of evidence used to support the hypothesis are that the continents seem to fit together like puzzle pieces, there are fossils of the same plants and animals on continents that are now separated by oceans, there are rock formations and mountain ranges on different continents that are similar in age and …
What evidence supported Wegener’s hypothesis of continental drift quizlet?
The Theory of Continental Drift was proposed by Alfred Wegener in 1912. He used several pieces of evidence to support his theory including fossils, rocks, glacial markings, coal deposits and the fact that the continents fit together like a jigsaw puzzle. .
What evidence was discovered and used to help support the theory of continental drift?
Fossils of similar organisms across widely disparate continents encouraged the revolutionary theory of continental drift. Continental drift describes one of the earliest ways geologists thought continents moved over time. Today, the theory of continental drift has been replaced by the science of plate tectonics.
What evidence supports Alfred’s theory?
fossil evidence Alfred Wegener collected diverse pieces of evidence to support his theory, including geological “fit” and fossil evidence.
What is the evidence for continental drift quizlet?
Fossils of same creature have been found on different continents that are separated today but were once joined. For example. a 20 cm Mesosaurus reptile could not have swam 3000 miles across and ocean. It's more likely the continents were together and over 40 million years it walked.
What was Wegener’s evidence for continental drift quizlet?
The Theory of Continental Drift was proposed by Alfred Wegener in 1912. He used several pieces of evidence to support his theory including fossils, rocks, glacial markings, coal deposits and the fact that the continents fit together like a jigsaw puzzle. .
What evidence did Alfred Wegener provide to support his hypothesis of continental drift quizlet?
The Theory of Continental Drift was proposed by Alfred Wegener in 1912. He used several pieces of evidence to support his theory including fossils, rocks, glacial markings, coal deposits and the fact that the continents fit together like a jigsaw puzzle. .
What evidence did Wegener find for Pangaea quizlet?
Wegener showed that certain types of rocks on the continents would match with others in another continent. What did Wegener realize about the oldest rocks on the Afircan and South American continents? That they were connected together when the continents were arranged to form Pangaea.
What are Wegener’s three observations?
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 Alfred Wegener’s continental drift hypothesis quizlet?
What is the continental drift hypothesis? Proposed by Alfred Wegener, it states that Earth's continents have moved slowly to their current locations. All the continents were once connected as one landmass that broke apart 250 million years ago. This one landmass is called "Pangea," meaning "all land."
What is one piece of evidence that Wegener used to prove continental drift quizlet?
One of Alfred Wegener's pieces of evidence for continental drift was data from the seafloor. Wegener used fossil ferns to suggest that a supercontinent existed about 250 million years ago. Glacial grooves in rocks in Africa suggest that this continent was once located in a much colder place.
What evidence supports Wegener’s continental drift hypothesis quizlet?
What evidence supported the hypothesis of continental drift? How did fossils provide evidence for continental drift? Similar fossils occur on different continents. Because many of these organisms could not have crossed an ocean, this provides evidence that the continents were once connected.
What was the main reason Wegener’s continental drift hypothesis was rejected quizlet?
Wegener's hypothesis was rejected from geologists because he couldn't identify the cause of continental drift.
What evidence supports Wegener’s initial ideas about continental drift which later became the theory of plate tectonics?
Wegener's first piece of evidence was that the coastlines of some continents fit together like pieces of a jigsaw puzzle. People noticed the similarities in the coastlines of South America and Africa on the first world maps, and some suggested the continents had been ripped apart (3).
