Ashley disagrees with her teacher that Earth’s surface has changed over the centuries. She says that it is difficult to believe because no one was around during this time to see it with their own eyes, but she can see the 7 continents that make up earth’s surface now. Her classmates try to explain the evidence that can be used to support this theory of continental drifting. Which of the following best supports the theory of continental drift?
Question 5 options:
Classmate #1 says that the landmass called Pangea existed and we know this because all of the continents such as North America and South America fit together like puzzle pieces.
Classmate #2 says that the landmass called Pangea existed and we know this because fossil evidence found in Africa were only in Africa.
Classmate #3 says that the landmass called Pangea existed and we know this because fossils of similar animals were discovered on different continents that fit together like puzzle piece.
Classmate #4 says that the landmass called Pangea existed and we know this because fossils of similar animals were discovered on different continents that do not fit together like puzzle piece.
