Explanation:
Detailed explanation-1: -The main reason that Wegener’s hypothesis was not accepted was because he suggested no mechanism for moving the continents. He thought the force of Earth’s spin was sufficient to cause continents to move, but geologists knew that rocks are too strong for this to be true.
Detailed explanation-2: -Wegener suggested that perhaps the rotation of the Earth caused the continents to shift towards and apart from each other.
Detailed explanation-3: -By the 1960s, there was enough evidence supporting Wegener’s missing mechanism, seafloor spreading, allowing continental drift’s hypothesis to develop into the Theory of Plate Tectonics.
