Why was Alfred Wegner's Continential Drift Theory not accepted at the time he proposed it?

Question

a
There was sufficient evidence that there were long land bridges that connected all the major continents
b
Continental drift was not supported by the fossil record
c
Continental drift was not supported by geological features like mountain ranges.
d
The theory had sufficient evidence that the continents were aligned, but could not explain HOW the continents moved.

Answer 1

The correct answer is:

d. The theory had sufficient evidence that the continents were aligned, but could not explain HOW the continents moved.

Alfred Wegener's Continental Drift Theory was controversial mainly because, while he provided compelling evidence for the fit of the continents and the distribution of fossils and geological features, he could not explain the mechanism by which continents drifted apart. This lack of a convincing explanation for the movement was a major reason why the scientific community was skeptical of his theory at the time.
