Which fossil clues support the continental drift hypothesis?
1. Another fossil that supports the hypothesis of continental drift is Glossopteris (glahs AHP tur us). 2. This fossil plant has been found in Africa, Australia, India, South America, and Antarctica.
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 exists to support the existence of Pangea 3 points?
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.
What other evidence did Wegener need in order to convince scientists that his theory of continental drift was correct quizlet?
What other evidence did Wegener need in order to convince scientists that his theory of continental drift was correct? Wegener found coal in Greenland and claimed that this supported his ideas about continental drift. How does coal in Greenland support the idea of continental drift?
Which statement best supports the theory of continental drift quizlet?
Which statement best supports the theory of continental drift? The present continents appear to fit together as pieces of a larger landmass.
What evidence supports the theory of ocean floor?
Abundant evidence supports the major contentions of the seafloor-spreading theory. First, samples of the deep ocean floor show that basaltic oceanic crust and overlying sediment become progressively younger as the mid-ocean ridge is approached, and the sediment cover is thinner near the ridge.
Which does not support the theory of continental drift?
Scientists did not accept Wegener’s theory of continental drift. … Wegener suggested that perhaps the rotation of the Earth caused the continents to shift towards and apart from each other. (It doesn’t.) Today, we know that the continents rest on massive slabs of rock called tectonic plates.
How is plate tectonics supported by the apparent fit of the continental coastline?
This apparent fit is due to the fact the continents were once connected, and have since moved apart in what has been called continental drift . However, we now know that it is not just the continents that move, so a more correct term is plate tectonics .
What is the first lines of evidence suggesting the existence of plate tectonics?
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 evidence did Wegener not support his hypothesis of continental drift?
Which type of evidence was NOT used by Alfred Wegener to support his continental drift hypothesis? fossil.
Which piece of evidence would provide the strongest support for the hypothesis that Earth’s continents were once joined?
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.
Which statement would best support Wegener’s hypothesis?
The continents we see today are fragments of that supercontinent. To support his theory, Wegener pointed to matching rock formations and similar fossils in Brazil and West Africa. In addition, South America and Africa looked like they could fit together like puzzle pieces.
How rocks fossils and climate provide evidence 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. Wegener suggested that when the organisms were alive, the lands were joined and the organisms were living side-by-side.
Which two pieces of fossil evidence supports the idea of continental drift?
What are 2 important fossils used to support continental drift?
