List the four main pieces of evidence that supports continental drift

There are several key pieces of evidence for continental drift. Four of them are as follows:

1. The shape of the continents. If you look at the shape of the coastlines of continents, you can see that they would easily have fit together in the past. For example, the outward curve of the African coast matches the inward curve of the South American coast.

2. Fossils of extremely similar plants and animals have been discovered on opposite side of the Atlantic Ocean. The level of similarity between these fossils suggests that the organisms must once have lived in close proximity to one another.

3. Fossils have been discovered where the animal or plant that was fossilized could never have lived in the current climate. Tropical plant fossils have been discovered in the Arctic, for example. This suggests that the continents must once have had different climates, which supports the idea that they were once in different locations.

4. There are landforms on different continents that match one another. There are geologic regions in Africa, for example, that exactly match geologic regions in South America, and if the continents were joined together the geologic formations there would have been continuous.
