Answer 3

heres a list :)
There is much evidence that Pangaea existed and that the seven continents used to be as one. Here are just some:

1. The most obvious piece of evidence is that the eastern coast of South America fits almost perfectly with the western coast of Africa.

2. In the fossil record, remains of the therapsid Lystrosaurus as well as the plant Glossopteris have been found in South Africa, India, and Australia, three regions currently separated by thousands of miles of ocean.

3. Similarly, fossils of the freshwater reptile Mesosaurus have been found on the coasts of Brazil and West Africa.

4. A polar ice cap covered the southern end of Pangaea during the Carboniferous period, and glacial deposits of the same age and structure are found throughout the southern continents.

5. The continuity of mountain chains also provides evidence. For example, the Appalachian Mountains extend from the northeastern US to the Caledonides of Ireland, Britain, and Scandinavia.

6. Paleomagnetic study of rocks can help scientists reconstruct the exact positions of continents at specific points in Earth's history.

7. There is direct evidence from very accurate measuring techniques that the movement of the continents is continuing today.
