question 3 (0.83 points)
while the geosyncline theory of mountain formation was accepted into the 1960s, it
had a hard time explaining
none of these are correct
the possible existence of deep ocean trenches
intercontinental terrestrial fossil matchup on both sides of the atlantic
the formation of mountains from compressed sedimentary rock
modern volcanic activity

Explanation:

The geosyncline theory focused on sediment accumulation and compression to form mountains, but it could not account for the matching terrestrial fossils across the Atlantic, as this requires continental movement, which the theory did not incorporate. It could explain mountain formation from compressed sedimentary rock, and while it didn't address trenches or volcanic activity perfectly, the fossil matchup was a key gap that led to its replacement by plate tectonics.

Answer:

C. intercontinental terrestrial fossil matchup on both sides of the Atlantic
