Question

Wegener proposed continental drift after he observed evidence from fossils, glacial deposits, and the fit of the continents that suggested all of the continents were once ____________.
A. aligned north to south along the prime meridian during the late Cenozoic
B. aligned east to west along the equator during the late Mesozoic through the Cenozoic
C. combined to form a supercontinent (he termed Rodinia) in the Proterozoic
D. combined to form a supercontinent (he termed Pangaea) in the late Paleozoic through the Mesozoic

Answer 1

Answer:

D. combined to form a supercontinent (he termed Pangaea) in the late Paleozoic through the Mesozoic

Explanation:

• Alfred Wegener in order to prove his hypothesis and develop a theory made the following proofs based on his study:  

1. Geologic similarities of rocks.
2. Climate similarities in continents
3. Jigsaw fit of the landmasses.
4. Same flora and fauna in African and American lands.
5. Glacial evidence of landmass formations.
6. Coal and gold deposits.

• All these factors he presented as evidence to the drifting of the continents and the splitting of the super landmasses away form each other.

• These were the in his theory of continental drift presented in 1912, with the occurrence of the Pangea 335 mn years ago, and broke off about 175 mn years ago.
