Question

1. which of the following did wegener give as evidence for continental drift? select four.

pick up to 4 answers.
a matching rock sequences
b. glacial evidence
c. sea-floor spreading
d. same fossil species
e. mid-ocean ridge
f fit of continents

Explanation:

• Matching rock sequences: Similar rock formations on different continents support the idea that continents were once connected.
• Glacial evidence: Glacial deposits in regions that are now tropical or temperate suggest continents were in different positions.
• Same fossil species: Fossils of the same species found on widely separated continents imply those continents were once adjacent.
• Fit of continents: The complementary shapes of continents like South America and Africa indicate they were once part of a single landmass.
• Sea - floor spreading and mid - ocean ridge are related to plate tectonics (a later theory that built on continental drift), not evidence Wegener used for continental drift.

Answer:

A. Matching rock sequences, B. Glacial evidence, D. Same fossil species, F. Fit of continents
