What evidence is there that the continents were once all together?
The evidence for continental drift included the fit of the continents; the distribution of ancient fossils, rocks, and mountain ranges; and the locations of ancient climatic zones.
What evidence supports the idea that all the continents were once joined together gizmo?
What evidence supports the idea that all the continents were once joined together? Similar rocks found on different continents. Mountains created by colliding continents. Evidence of glaciers in unexpected places.
What evidence did you consider in determining which continental boundaries be joined?
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 evidence is there to support Pangea existed?
The rock formations of eastern North America, Western Europe, and northwestern Africa were later found to have a common origin, and they overlapped in time with the presence of Gondwanaland. Together, these discoveries supported the existence of Pangea.
Which clue is used to show that the continents used to fit together in a supercontinent millions of years ago?
Use fossil and rock evidence to reconstruct how the Earth may have looked approximately 290 million years ago when the continents were connected to form a supercontinent called Pangea.
Why did Wegener think that fossil evidence showed that the continents must once have been joined?
There are various examples of fossils found on separate continents and in no other regions. 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.
What evidence supports the idea that all the continents were once joined together quizlet?
What evidence supports the idea that all the continents were once joined together? Similar rocks found on different continents. Mountains created by colliding continents. Evidence of glaciers in unexpected places.
What is the evidence that scientists use to prove the continents of Africa Antarctica and South America were once joined?
There are many examples of fossils found on separate continents and nowhere else, suggesting the continents were once joined.
What are the 5 evidences of continental drift?
They based their idea of continental drift on several lines of evidence: fit of the continents, paleoclimate indicators, truncated geologic features, and fossils.
What evidence did Wegener use to develop the continental drift theory?
Wegener supported his theory by demonstrating the biological and geological similarities between continents. South America and Africa contain fossils of animals found only on those two continents, with corresponding geographic ranges.
What are 3 pieces of evidence for Pangea?
They based their idea of continental drift on several lines of evidence: fit of the continents, paleoclimate indicators, truncated geologic features, and fossils.
Which piece of evidence supports the theory of continental drift?
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.
What were 3 pieces of evidence for Wegener’s continental drift theory?
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.
Which theory has provided explanations to Wegener’s claim of moving continents?
The theory of continental drift is most associated with the scientist Alfred Wegener. In the early 20th century, Wegener published a paper explaining his theory that the continental landmasses were “drifting” across the Earth, sometimes plowing through oceans and into each other.
Which of these provides the best evidence for the continental drift theory?
Q. Which of the following statements about Glossopteris fossils provides the best evidence to support Wegener's Continental Drift theory? Glossopteris fossils are found in India, South America, Australia, Africa, and Antarctica. This distribution is best explained by tectonic plate movement.
What three evidence supports Wegener’s theory?
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. .
How did other scientists explain why the continents seemed to fit together?
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.
What are the 4 evidences of continental drift theory?
They based their idea of continental drift on several lines of evidence: fit of the continents, paleoclimate indicators, truncated geologic features, and fossils.
What is the evidence for continental drift and plate tectonics?
Fossil Evidence One type of evidence that strongly supported the Theory of Continental Drift is the fossil record. Fossils of similar types of plants and animals in rocks of a similar age have been found on the shores of different continents, suggesting that the continents were once joined.
What discovery provided strong support for continental drift?
Increased knowledge about the configuration of the ocean floor and the subsequent formulation of the concepts of seafloor spreading and plate tectonics provided further support for continental drift.
What were the 4 main evidence of continental drift?
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.
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.
Which of the following is the best evidence that Earth’s continents?
The best evidence that the continents were once connected is that they have matching… rock types, fossils, and coastlines. Which of these describes a divergent boundary? Two continental plates moving away from each other, forming a rift valley.
What evidence supported Wegener’s 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 supports the theory of continental drift?
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.
What evidence did Alfred use?
He used fossil evidence, such as that of tropical plants found on the Arctic island of Spitzbergen. He found large-scale geographic features that matched, like the Appalachian Mountains in the United States and the Scottish Highlands, as well as rock strata in South Africa that matched those in Brazil.
What was Wegener’s evidence for his theory?
Wegener supported his theory by demonstrating the biological and geological similarities between continents. South America and Africa contain fossils of animals found only on those two continents, with corresponding geographic ranges.
Which of these are evidence for continental drift?
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.
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.
Which of the following is the best evidence that Earth continents were once in a vastly different position than they are today?
Which of the following is the best evidence that Earth's continents were once in vastly different positions than they are today? Fossils of tropical plants are found in Antarctica.
