Final answer:
The fit of the continents, matching fossil records, and similar rock formations provide evidence that supports Wegener's hypothesis of continental drift.
Step-by-step explanation:
One kind of evidence that supports Wegener's hypothesis of continental drift is the fit of the continents. Wegener noticed that the coastlines of Africa and South America fit together like puzzle pieces. This fit indicated that the continents had once been joined together and had subsequently moved apart. For example, the eastern coastline of South America fits perfectly into the western coastline of Africa.
Another line of evidence is matching fossil records. Wegener found that similar fossils of plants and animals were found on different continents that are now separated by oceans. For instance, fossils of the freshwater reptile Mesosaurus were found in both Africa and South America, suggesting that these continents were once connected.
The third piece of evidence is the presence of similar rock formations and mountain ranges on different continents. Wegener observed that the Appalachian Mountains in North America matched up with the Caledonian Mountains in Europe, indicating that these regions were once joined together.
