Question: Look at the map that shows the continents 200 million years ago. Based on the map, which continent would be the most likely to have rock sequences and ages similar to those shown in Africa and South America? Explain why.

Answer 1

Based on the map of continents from 200 million years ago, the continent that would likely have rock sequences and ages similar to those in Africa and South America is Antarctica.

The reason for this similarity lies in the theory of plate tectonics and the historical configuration of continents during the time of Pangaea. Approximately 200 million years ago, the continents were joined together in a single supercontinent known as Pangaea. During this time, the landmasses were connected, which means that the geological formations, rock types, and ages in one region would often reflect those in adjacent regions.

Africa and South America share many geological features and similar fossil records due to their past connection on the Pangaea supercontinent. Similarly, Antarctica was also part of this supercontinent and was positioned adjacent to both Africa and South America. Therefore, it is likely that the rock sequences and ages found in Antarctica would be comparable to those in Africa and South America because they all were formed during the same geological period and under similar environmental conditions before the continents drifted apart.
