What evidence did alfred wegener use to support his theory of continental drift?

The answer would be:

Coastline fits between different continents, similar rocks and fossils on different continents.

Hope this helps!

Explanation:

Alfred Wegener was a meteorologist and geologist. He was inspired by a map of continents to start the journey of explaining Earth's geological history. He gave the theory of continental drift which says that the continents of Earth have moved relative to each other over time. He used following evidences to support his theory:

1. The facing side of South America's and Africa's shoreline interlocks perfectly. Which implies they must have been joined together in history.

2. Fossil of same type of reptiles found on different continents separated by huge oceans.

3. Matching the rock pieces on either side of the Atlantic oceans.

hi there!

out of the two, (b) precision would be more reasonable.   however, both a and b could be pretty reasonable.
