Question

what source of evidence did wegener use to support his theory of continental drift?

• fossils found on earth
• magnetic fields of earth
• satellite mapping of the tropical islands
• glaciers found near the poles

Explanation:

Wegener used evidence like the fit of continents (e.g., South America and Africa), fossil distribution (like Mesosaurus fossils found in both), and rock formations across continents. Among the options, "fossils found on Earth" (assuming it's about fossil evidence across continents) relates to his use of fossil records to support continental drift. The other options: magnetic belts were used later for seafloor spreading, satellite mapping didn't exist then, and glaciers near poles is part of paleoclimatic evidence but fossils are a key Wegenerian evidence.

Answer:

A. fossils found on Earth (assuming the first option is "fossils found on Earth" as per the context of Wegener's continental drift evidence)
