Introduction: In 1915, a German scientist named Alfred Wegener (VAY-guh-ner) proposed the theory of continental drift. According to this theory, the landmasses once were joined into a supercontinent called Pangaea. The landmasses then slowly drifted to their current positions. - What did Pangaea look like?

Observe: Drag South America close to Africa. Look at their coastlines. What do you notice?

As much as possible, avoid overlapping landmasses.
When you are satisfied, take a screenshot and paste it into your document. Label this map “Map 2: Fit of the continents.”

Analyze: Look at your map of Pangaea.

- How well do the continents fit together?
- Is it a perfect fit? Explain.

Think about how the landmasses got from where they were to where they are today. Does it seem realistic that the landmasses could have moved like this? Explain.

Compare: If possible, present your map of Pangaea to your classmates and teacher. Look at other maps, and talk about each one.

- Are the maps very similar or very different?

If Alfred Wegener showed you a map like this but did not have any other evidence, would you have believed his theory that the continents had moved? Explain.
