One main objection to Wegner's continental drift hypothesis was the lack of a plausible mechanism to explain how continents could move through solid oceanic crust. At that time, the idea of continental drift contradicted prevailing scientific beliefs about the rigidity of the Earth's crust.
I think that continetal drift replaced his theory
Wegener's hypothesis of continental drift was rejected because he lacked a plausible mechanism to explain how the continents moved. Additionally, the scientific community at the time did not have sufficient evidence to support the idea of continents drifting. It wasn't until the theory of plate tectonics emerged later, providing a mechanism and supporting evidence, that continental drift became widely accepted.
Scientists rejected Wegener's theory of continental drift initially because he did not have a plausible mechanism to explain how the continents moved.

It was only later, with the development of plate tectonics theory, that Wegener's idea gained widespread acceptance.
The hypothesis of continental drift was proposed by Alfred Wegener in 1912 to explain the jigsaw-like fit of continents, similarities in rock types and fossils, and paleoclimate data. It wasn't widely accepted until the 1960s when evidence from paleomagnetism and seafloor spreading supported the theory.
The continental drift hypothesis proposed by Alfred Wegener in the early 20th century suggested that Earth's continents were once joined together in a single landmass called Pangaea and have since drifted apart. This movement of continents has affected sea levels by altering the distribution of land and ocean basins, which in turn can impact global climate patterns and sea levels through changes in ocean circulation, tectonic activity, and the melting of polar ice.
He could not explain how or why the continents moved.
The hypothesis you are looking for is continental drift.

One key piece of evidence that was not initially used in support of the continental drift hypothesis was a mechanism explaining how continents could move. It wasn't until the discovery of plate tectonics and the development of the theory of seafloor spreading that a mechanism was found to explain how continents drift.
