What evidence did the Deep Sea Drilling Project find about the dates of rocks in the ocean basins?
What evidence did the Deep Sea Drilling Project find about the dates of rocks in the ocean basins? The ocean basins are relatively young; most ocean basin rocks and sediments are Cretaceous or younger in age. Which of the following was never proposed as evidence supporting the existence of Pangaea?
What evidence exists to support the existence of Pangea quizlet?
Fossils of identical organisms were found on several continents, indicating the continents were once joined. Late Paleozoic sedimentary rocks often contain extensive coal seams that were used to support the existence of Pangaea.
What evidence supports the idea that all the continents were once joined together?
Fossil Evidence 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. For example, fossils of Mesosaurus, a freshwater reptile, have been found both in Brazil and western Africa.
What evidence indicated scientists that the continents were once connected?
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).
Why did scientists not accept the continental drift hypothesis?
The main reason that Wegener's hypothesis was not accepted was because he suggested no mechanism for moving the continents. He thought the force of Earth's spin was sufficient to cause continents to move, but geologists knew that rocks are too strong for this to be true.
What are the evidences of plate movement found in your constructed Pangaea?
There is variety of evidence that supports the claims that plate tectonics accounts for (1) the distribution of fossils on different continents, (2) the occurrence of earthquakes, and (3) continental and ocean floor features including mountains, volcanoes, faults, and trenches.
Which of the following provides evidence for plate tectonics?
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.
Which of the following is not evidence used by Wegener in his hypothesis of continental drift?
Wegener's continental drift hypothesis did not give a plausible explanation for how continents move. Wegener's continental drift hypothesis did not state that the continents were arranged into a supercontinent many millions of years ago.
Which of the following pieces of evidence supports the plate tectonic theory?
There is variety of evidence that supports the claims that plate tectonics accounts for (1) the distribution of fossils on different continents (2) the occurrence of earthquakes and (3) continental and ocean floor features including mountains volcanoes faults and trenches.
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 proves that 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 was not used in support of the continental drift hypothesis?
Explanation. Wegener did not use paleomagnetism to support his continental drift hypothesis.
How do we know 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 of the following was not used in support of the continental drift hypothesis?
Explanation. Wegener did not use paleomagnetism to support his continental drift hypothesis.
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.
Which two pieces of evidence does not support plate tectonics?
Which 2 pieces of evidence does not support plate tectonics? All volcanoes that occur over a hotspot are not associated with plate boundaries. Rocks made of basalt (charcoal colored rock), which formed at the same time, point to the same magnetic north.
What are the 5 evidences of plate movement?
There is variety of evidence that supports the claims that plate tectonics accounts for (1) the distribution of fossils on different continents, (2) the occurrence of earthquakes, and (3) continental and ocean floor features including mountains, volcanoes, faults, and trenches.
What are the 4 evidences of plate movement?
There is variety of evidence that supports the claims that plate tectonics accounts for (1) the distribution of fossils on different continents, (2) the occurrence of earthquakes, and (3) continental and ocean floor features including mountains, volcanoes, faults, and trenches.
What evidence supports plate tectonics quizlet?
What are the five main pieces of evidence for the Theory of Plate Tectonics? Magnetic striping, Age of the ocean's crust rocks, Coral islands, The position of ocean trenches and the locations of earthquakes and volcanoes.
Why did no one believe Wegener’s theory?
The main reason that Wegener's hypothesis was not accepted was because he suggested no mechanism for moving the continents. He thought the force of Earth's spin was sufficient to cause continents to move, but geologists knew that rocks are too strong for this to be true.
Which of these pieces of evidence did Alfred Wegener cite to support his hypothesis 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.
Which of the following pieces of evidence supports the plate tectonics theory quizlet?
Which of the following pieces of evidence supports the plate tectonic theory? The stripe patterns of high- and low-intensity magnetism are mirror images on both sides of an oceanic ridge. You just studied 21 terms!
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.
What are 5 pieces of evidence that support 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.
Which of the following was not evidence that is used to propose the theory of continental drift?
Wegener's continental drift hypothesis did not state that the continents were arranged into a supercontinent many millions of years ago. Wegener's continental drift hypothesis did not give an accurate estimate for the length of time involved in continent motion.
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.
