Question

alfred wegener proposed the idea of continental drift in 1912. what main type of evidence did he use to support his theory?
measurements from earthquakes
satellite images of moving continents
seafloor spreading and mid - ocean ridges
fossil distribution, rock types, and mountain ranges

Explanation:

Alfred Wegener used evidence such as the matching of fossil distributions across continents, similar rock - types, and continuous mountain ranges on separated landmasses to support his continental drift theory. Earthquake measurements, satellite images, seafloor spreading, and mid - ocean ridges were not available or well - understood in 1912 when he proposed his theory.

Answer:

Fossil distribution, rock types, and mountain ranges
