Answer:
Collect common fossil evidence from the South American and African plates.
Explanation:
When we study plate movements, we are interested in learning how the surface of the Earth has changed over time. One of the ways in which this can be discovered is by studying areas that might have been different in the past. An example is to study the common fossil evidence from the South American and African plates. This would be useful due to the fact that the two plates are believed to have been together at some point in the past.
