Wegener made use of what evidence to develop the theory of continental drift?

Question

Responses

1) The Rocky Mountains are taller than the Appalachian Mountains despite being made up of a much softer, weaker rock.
2) The climate of Siberia has always been the same.
3) There is no evidence of glaciers anywhere in South America.
4) Mountains in North America appear to be part of the same chain of mountains as those in Northern Europe.

Answer 1

Wegener developed the theory of continental drift based on several lines of evidence, one of which is:

4. Mountains in North America appear to be part of the same chain of mountains as those in Northern Europe.

This observation supported the idea that continents were once joined together and have since drifted apart, as similar mountain ranges on different continents suggested a shared geological history. Other evidence Wegener used included the distribution of fossils, the fit of continental coastlines, and geological similarities across continents.
