Alfred Wegener cited the following pieces of evidence to support his hypothesis of continental drift:
- The continents fit together like a puzzle.
- Similar fossils have been found at different continents that are now separated by oceans. (Note: The option you provided about fossils at the bottom of the ocean is not accurate in the context of Wegener's arguments; he focused on land fossils.)
- Matching geological formations and mountain ranges on different continents.
However, the statement regarding "New oceanic crust formed between the northern and southern continents" refers to the theory of plate tectonics, which was developed later and not by Wegener.
Likewise, "Contraction of the Earth caused folded mountains to form" was part of earlier geological theories but was not a basis for Wegener's continental drift hypothesis.
To summarize, the correct response based on Wegener's evidence would be that the continents fit together like a puzzle and similar fossils found on different continents (though the specific phrasing about the ocean may not be accurate).
