How do climate clues explain continental drift?
How did Wegener use climate clues to support his hypothesis of continental drift? Wegener used continental drift to explain evidence of changing climates. For example, fossils of warm-weather plants were found in the Arctic Ocean, and glaciers were found in warm areas, such as Africa.
What are the 4 evidences 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.
How does evidence of ancient climates support continental drift?
What does ancient climate evidence suggest about continental drift? Wegener noticed that rocks often indicate an ancient climate that is very different that the present day climate. Some rocks located in warm climates today were deposited by glaciers 300 million years ago.
What evidence best supports continental drift?
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 are 5 pieces of evidence for continental drift?
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 are 6 pieces of evidence that support 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 was the first evidence of continental drift?
Wegener used fossil evidence to support his continental drift hypothesis. The fossils of these organisms are found on lands that are now far apart. Grooves and rock deposits left by ancient glaciers are found today on different continents very close to the equator.
How did Wegener use fossils to prove continental drift?
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.
How does science prove that the continents are drifting?
Seafloor spreading is most dynamic along giant underwater mountain ranges known as mid-ocean ridges. As the seafloor grows wider, the continents on opposite sides of the ridge move away from each other. … These processes were the main geologic forces behind what Wegener recognized as continental drift.
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.
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. Why was the theory of continental drift not accepted early on?
What evidence did Wegener rely on in the formulation of his theory of continental drift What evidence did he lack?
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 of these did not provide evidence for continental drift?
divergent. Which of these did NOT provide evidence for continental drift? oceanic plate theory. Where does sea-floor spreading take place?
