What evidence supports the theory of 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 6 evidences of plate tectonics?

Evidence for Plate Tectonics

• Shape of continents. From almost the creation of the first true maps of the Earth, people started seeing how continents would be able to fit together.
• Location of mountains and fossils.
• Earthquakes and Volcanoes.
• Hot Spot Volcanoes.

Who came up with supporting evidence for plate tectonics?

Theory of Plate Tectonics was established by Alfred Wegener. Fossils and Mountain ranges were his evidences. Alfred Wegener created the idea of continental drift and wrote ‘The Origin of Continents and Oceans’ to support his idea. His theory was rejected by geologists at first.

What is one point of evidence that support the theory and show how the plates used to be aligned?

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 plate tectonics 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 pieces of evidence supports the plate tectonic theory quizlet?

The volcanoes of Hawaii are localized above a deep mantle hot spot; they are not part of the East Pacific oceanic ridge. continents and oceans. -The expression of a divergent plate boundary.

What are the 5 evidences of continental drift theory?

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 evidence shows that the Pacific plate moving?

The evidence for this motion is pretty convincing: earthquakes: earthquakes occur on the boundaries of the plates as they rub past each other. The motion observed during these earthquakes agrees well with the expected motion.

What evidence supports Wegener’s hypothesis?

The fossils of the reptiles Mesosaurus and Lystrosaurus and a fernlike plant called Glossopteris have been found on widely separated landmasses. This convinced Wegener that the continents had once been united. Wegener used evidence from climate change to further support his theory.

How does paleomagnetic evidence support the theory of plate tectonics?

Paleomagnetism also provides evidence to support theories in plate tectonics. Because the ocean floor is mostly composed of basalt, an iron-rich substance containing minerals that align with the magnetic field, they record the alignment of the magnetic fields surrounding oceanic ridges.

Which of the following is most recent evidence of plate tectonics?

Volcanic activity and sea-floor spreading at the mid-ocean ridges are the most recent evidence of plate tectonics.
