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.
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.
What are the two main factors of tectonic plates movement?
Heat and gravity are fundamental to the process The energy source for plate tectonics is Earth's internal heat while the forces moving the plates are the “ridge push” and “slab pull” gravity forces.
What is the evidence used to support the plate tectonics theory quizlet?
Rock and fossils found in South America match those found in Africa, although there is an ocean in between. This also indicates that the two continents were once joined. Other evidence of plate tectonics include Seafloor spreading, which involves the creation of new crust at divergent plate boundaries.
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.
What are the 3 theories of plate tectonics?
The three types of plate boundaries are divergent, convergent, and transform.
What are the 3 causes of plate movement?
Scientists have theorized three mechanisms that cause plate movement on Earth. These three mechanisms are thermal convection, ridge push, and slab pull.
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 are 2 pieces of 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 are three pieces of 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. Some life "rode" on diverging plates, became isolated, and evolved into new species.
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.
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 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.
Which is 1 piece of evidence of seafloor spreading?
What is one piece of evidence of seafloor spreading? The age of the oceanic crust gets older the further you go from a mid-ocean ridge. The age of the oceanic crust gets younger the further you go from a mid-ocean ridge. The age of the oceanic crust is the exactly the same no matter where you go.
What is one piece of 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 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 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.
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 the two 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.
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.
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.
What two pieces of fossil evidence support the idea of continental drift?
The similarities between the Appalachian and the eastern Greenland mountain ranges are evidences for the continental drift hypothesis. Ancient fossils of the same species of extinct plants and animals are found in rocks of the same age but are on continents that are now widely separated (figure 3).
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 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 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 two fossils are found on two more continents and evidence for Pangaea?
Two fossils in particular served as good evidence for the idea that the continents were once joined but have since separated: Glossopteris and Mesosaurus.
