What are the 4 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 are the 3 evidence that support 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 type of evidence support the idea that the continents were not always where they are today?
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 kind of evidence was not used in support of continental drift?
Terms in this set (10) Which type of evidence was NOT used by Alfred Wegener to support his continental drift hypothesis? fossil.
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 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 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 supports the claim of Earth’s continents?
Which evidence supports the claim that Earth's continents formed during Precambrian time? Earth's surface cooled, causing rocks to cool and harden. Why is radioactive dating important when approximating the age of Earth? Scientists can determine the order of when rocks formed on Earth.
How do we know the continents have moved?
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 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 is used as evidence for seafloor spreading?
Harry Hess's hypothesis about seafloor spreading had collected several pieces of evidence to support the theory. This evidence was from the investigations of the molten material, seafloor drilling, radiometric age dating and fossil ages, and the magnetic stripes.
What causes continental drift quizlet?
a current caused by the rising of heated fluid and sinking of cooled fluid. The earth's crust and upper mantle are made of huge plates slowly drifting because of convection currents in the mantle.
Which of the following is true about the movement of continents?
Which of the following is TRUE about the movement of continents? Continents move along with the plate they are part of. Which of the following is TRUE about the movement of ocean basins? Ocean basins move along with the plate they are a part of.
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 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 did you consider in determining which continental boundaries should be joined?
Evidence from fossils, glaciers, and complementary coastlines helps reveal how the plates once fit together.
What evidence supports the claim that Earth’s surface is made up of slabs of rock that are moving relative to each other?
Early scientists inferred that there was once a large mass of land and may have moved against another. Another evidence is the polarity of the ocean floor. Early oceanographers found magnetic variations in seafloors that are different from continental crusts.
What made continents move?
The movement of these tectonic plates is likely caused by convection currents in the molten rock in Earth's mantle below the crust. Earthquakes and volcanoes are the short-term results of this tectonic movement. The long-term result of plate tectonics is the movement of entire continents over millions of years (Fig.
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 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 are 3 types of evidence for seafloor spreading?
The pieces of evidence gathered for sea-floor spreading include the evidence from molten material, magnetic stripes, and drilling samples.
Which of the following is the single best evidence in support of the concept of seafloor spreading?
Evidence of Magnetic stripes It was the greatest support of sea fall spreading.
What evidence supports the theory 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 is continental drift theory quizlet?
Theory of Continental Drift. In 1915, the German geologist and meteorologist Alfred Wegener first proposed the theory of continental drift, which states that parts of the Earth's crust slowly drift atop a liquid core. The fossil record supports and gives credence to the theories of continental drift and plate tectonics …
What are the evidences of plate movements?
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. Some life "rode" on diverging plates, became isolated, and evolved into new species.
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.
Who found evidence that the continents were joined together at one time?
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. He called this movement continental drift.
What are two types of evidence that support the moving of the continents?
Modern continents hold clues to their distant past. Evidence from fossils, glaciers, and complementary coastlines helps reveal how the plates once fit together.
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 was the main reason that Wegener’s continental drift hypothesis was not accepted by other scientists at the time?
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.
