Wegener's continental drift hypothesis was weakened because a viable mechanism for moving the continents was lacking?

Yes, they could not find a reason that would cause the movements of the continents. Now, scientists have discovered that the continents don't drift, but rather they are carried by tectonic plates.

Wegeners hypothesis of continental drift was replaced in 1967 by which theory that supported his idea continents move?
plate tectonics
What was the reason wegeners continental drift hypothesis was rejected?
His evidence was incorrect.
Wegeners hypothesis of continental drift was finally confirmed by?
evidence supporting the idea of sea-floor spreading.
Why was the wegeners hypothesis o the continental drift not widely accepted at the time it was proposed?
Although it seemed to make a lot of sense, there was no known proof of HOW the continents would drift. It wasn't until years later that we gained knowledge of plate tectonics, which bolstered Wegener's hypothesis.
What was the main reason wegeners continental drift was rejected?
He could not provide a wholly acceptable explanation for the movement of the continents.
Why is ''cotinental drift'' an appropriate title for wegeners theory?
Because Continental drift is when the continents drift apart because they hate each other.
What evidence supports his hypothesis?
The evidence that supports wegeners hypothesis is the fossil evidence
Why was wegeners theory of continental drift?
While geological research during the sixties had shed new light into the theory, it was J. Tuzo Wilson's proposal of a mechanism for continental drift what led to widespread acceptance of the theory. Proposing a feasible mechanism was something Wegener himself had failed to do, he had only proposed some evidence (complementary Coastlines and fossil distributions across continents.) and falsified mechanisms (like Earth's centrifugal pseudoforce).
How did discovery of glossopteris support Wegeners continental drift hypothesis?
Because identical fossils were found on two continents far apart, it suggested that at one time the two landmasses were joined together. In other cases of lands separated by far less distance, plants did not propagate across the divide.

What evidence did Wegeners have to support his theory?
Fossils support his hypothesis.
What discovery led scientists to accept Wegeners continental drift hypothesis?
One day while scientists were exploring the sea floor, they discovered sea-floor spreading, thus proving Wegener's hypothesis to be correct.
