Which fossil occurs on the most landmasses What does this suggest about when these particular continents broke up quizlet?
The Lystrosaurus reptile. It suggests that when the continents broke up the reptiles continued to exist on their new landmasses.
How the fossils evidence helped you to put the landmasses together?
Alfred Wegener collected diverse pieces of evidence to support his theory, including geological “fit” and fossil evidence. This indicates that these continents had to be once joined together because the extensive oceans between these land masses act as a type of barrier for fossil transfer.
Is the matching of large scale geological features on different continents?
Geological “fit” evidence is the matching of large-scale geological features on different continents. The coastlines of South America and West Africa seem to match up. These rocks are different from rocks found in other places on Earth, suggesting that the continents were once connected.
What clues did you use to put the continents together?
Wegner’s Evidence for Continental Drift Evidence from fossilized organisms and mountain chains can be used to reconstruct the positions of today’s continents and landmasses to form the supercontinent Pangea. Glossopteris ferns had very heavy seeds that could not move by wind or drift on ocean currents.
How do we know that Pangea existed?
How did scientists “discover” Pangea and other supercontinents of the past? Nowadays, they can study the geologic record and use radioactive dating, seismic surveys, and other technologies to construct maps of how the world looked at various points in Earth’s history.
Why is flying over Antarctica illegal?
A Lack of Infrastructure. It is fair to say that there isn’t much infrastructure on Antarctica at all, let alone towers and airports and other structures which can help airplanes take off, land, and navigate. The lack of such an infrastructure can make flying over Antarctica like flying over the sea.
