Rebuild Past Continents Practice Test

Students have a past continental reconstruction model based on (1) matching fossils and (2) matching rock types along two coastlines. The teacher asks: which additional evidence would most improve confidence in the reconstruction (without relying on only one kind of evidence)?

A student proposes a past reconstruction where Continent D is flipped upside down to match a coastline. The evidence shown includes (1) matching fossils and (2) matching rock layers that have a clear “top” and “bottom” direction (layer order). Which reconstruction is incorrect, and why?

Use the idea that reconstructions are evidence-based models and must fit multiple evidence types.
