Question

1. how did similar mountain ranges support wegeners idea?

a. they showed earthquakes happen at the same time worldwide
b. they suggested certain mountain ranges were once part of the same larger range before continents separated
c. they proved mountains always form in the same place
d. they were formed by the same volcano

Explanation:

Wegener's idea is continental drift, which proposes that continents were once a single supercontinent (Pangaea) and later drifted apart. Similar mountain ranges on separate continents match in age, structure, and rock type, indicating they were originally a single continuous range before continental separation. Options A, C, and D are incorrect: earthquakes timing is unrelated, mountains do not always form in the same place, and these ranges were not formed by the same volcano.

Answer:

B. They suggested certain mountain ranges were once part of the same larger range before continents separated
