Question

what evidence did alfred wegener use to support his theory of continental drift?
coastline fits between different continents only
wegener had no evidence, which is why his theory was rejected.
coastline fits between different continents, similar rocks and fossils on different continents

Explanation:

Alfred Wegener used multiple types of evidence. The fit of coastlines between different continents was one clue, like how South America and Africa seem to fit together. Also, the presence of similar rocks and fossils on different continents indicated they were once connected. His theory wasn't rejected for lack of evidence but due to lack of a good mechanism for the drift at the time.

Answer:

coastline fits between different continents, similar rocks and fossils on different continents
