One of the evidences that Wegener used for his theory of continental drift was that the mountains in North America appear to be part of the same chain of mountains as those in Northern Europe.
Explanation:
Alfred Wegener is considered to be the first person that managed to gather enough evidence and push through the theory of continental drift. This was not an easy task though, as the technology was still not at as developed as it is now, and also there was big skepticism among the other scientists about his suggestions. Wegener was not discouraged, but instead he totally focused his career on the continental drift theory, and eventually it paid off.
One of the evidence that Wegener was using was that the mountains in the eastern part of North America appear to part of the same chain of mountains as those in Northern Europe. Wegener was right, as the Appalachian Mountain Range and the mountains in Scandinavia are actually formed as part of the same orogeny, and they were indeed connected. Over time Europe and North America drifted apart, but the evidence are there to be seen
Other evidence that Wegener used for his theory are:
- the matching coastlines of South America and Africa
- fossil evidence
- geological evidence
- mid-Atlantic Ocean ridge
