What is the strongest piece of evidence for plate tectonics?
Stripes of magnetic material in the seafloor provide strong evidence for tectonic theory. The stripes alternate between those with magnetic material orientated toward magnetic north, and those oriented in the opposite direction. Seafloor spreading is the mechanism behind this phenomenon.
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.
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.
Which of the following is evidence supporting plate tectonics and 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 is evidence for plate tectonics on Earth quizlet?
There is a great deal of scientific evidence in support of plate tectonics. Coastlines on opposite continents appear to fit together like puzzle pieces, indicating that they were once joined. Rock and fossils found in South America match those found in Africa, although there is an ocean in between.
Which of the following was early evidence for plate tectonics?
Rock unearthed from a mountain belt in northeastern South Africa has shown the earliest known evidence of plate tectonics, pre-dating their previous known existence by 240 million years, according to researchers.
Which of the following provides evidence for past tectonic plate motions?
Q. Which of the following provides evidence for past tectonic plate motions? Matching rock type and rock formations can show the way the continents were once attached. Glacial evidence has been found in areas where glaciers could exist if the continents were in their current location.
What are two pieces of evidence used to support 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.
Which of the following are lines of evidence for plate tectonic theory quizlet?
The theory of plate tectonics is supported by fossils, the shape of continents, the mid-ocean ridge system, sea floor sediment deposits, and the magnetism of rocks on the sea floor.
Which of the following is evidence of plate tectonics quizlet?
There is a great deal of scientific evidence in support of plate tectonics. Coastlines on opposite continents appear to fit together like puzzle pieces, indicating that they were once joined. Rock and fossils found in South America match those found in Africa, although there is an ocean in between.
Can you identify and describe at least 2 fossil evidence that support plate movement?
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 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 was Wegener’s evidence for his theory?
Wegener knew that fossil plants and animals such as mesosaurs (opens in new tab), a freshwater reptile found only in South America and Africa during the Permian period, could be found on many continents. He also matched up rock formations on either side of the Atlantic Ocean like puzzle pieces.
What evidence do we now have for the theory of plate tectonics from the seafloor?
The pieces of evidence gathered for sea-floor spreading include the evidence from molten material and the magnetic stripes or patterns on the floor of the ocean. All these discoveries are linked to the formation, movement, and subduction that happen on the Earth's plates.
What is the fossil evidence for 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 is the first line of evidence in plate tectonics?
Fossil Distribution One of the first lines of evidence suggesting the existence of plate tectonics was the discovery of very similar fossils in rock masses separated by vast distances and by ocean expanses. It suggested that those land areas had in the past been connected.
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.
What are Wegener’s four pieces of evidence?
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 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 are the 2 evidence of seafloor spreading?
Several types of evidence from the oceans supported Hess's theory of sea-floor spreading-evidence from molten material, magnetic stripes, and drilling samples. This evidence also led sci- entists to look again at Wegener's theory of continental drift.
Which two pieces of fossil evidence support the idea of continental drift?
Observation of the fit of the continents into one large mass, Common Fossil Findings across continents, and Mid-Ocean Ridges The similarities between the Appalachian and the eastern Greenland mountain ranges are evidences for the continental drift hypothesis.
What are the evidences of plate?
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 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.
What are two pieces of evidence for seafloor spreading?
Several types of evidence from the oceans supported Hess's theory of sea-floor spreading-evidence from molten material, magnetic stripes, and drilling samples. This evidence also led sci- entists to look again at Wegener's theory of continental drift.
What was pieces of evidence that Alfred Wegener used?
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.

List four pieces of evidence for Wegener's hypothesis of continental drift? Continents fit like a puzzle, climate clues, fossil clues, and rock layers or formations.
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. .
