The correct answer is 4) all of the above.
Wegener presented multiple lines of evidence to support his theory of continental drift, including:
- The fitting together of continental shapes (like puzzle pieces).
- Fossil distribution across continents where similar species were found on landmasses that are now separated by oceans.
- Glaciation evidence and climate indicators suggesting that continents were once positioned differently.
- Mountain ranges and geological formations that align across continents, indicating they were once part of the same structure.
All of these pieces of evidence contributed to Wegener's argument for the movement of continents over geological time.
