Question

alfred wegener proposed a theory about continental movement. which statement serves as evidence that the continents were at one time joined together? ○ fossils from a certain species were found only on one continent. ○ a large variety of fossils were found on all continents. ○ fossils were found on the ocean floor. ○ fossils from the same species were found on different continents.

Explanation:

To determine evidence for continental drift (continents once joined), we analyze each option:

• Option 1: Fossils on only one continent doesn't suggest joining.
• Option 2: A large variety on all continents doesn't imply they were joined (could be different species).
• Option 3: Ocean - floor fossils relate to marine life, not continental joining.
• Option 4: Same - species fossils on different continents suggest the continents were once connected (the species lived in a single area when continents were joined, and then the continents drifted apart, carrying the fossils with them).

Answer:

D. Fossils from the same species were found on different continents
