What three puzzling occurrences that the theory of continental drift helped to explain and describe how it explained them?

The theory of continental drift helped explain the matching geological formations and fossil distributions across continents, such as the similar rock types found in the Appalachian Mountains of North America and the Caledonian Mountains in Scotland. It clarified the presence of identical fossils, like those of the Mesosaurus, found on both South America and Africa, suggesting these continents were once joined. Additionally, it accounted for the fit of continental Coastlines, particularly the east coast of South America and the west coast of Africa, indicating they were once part of a single landmass before drifting apart.
