Detailed explanation-1: -The main issue with Wegener’s Continental Drift Theory was he did not have a mechanism behind the drifting of continents. He had a substantial amount of evidence that made sense; nonetheless, without a driving force behind it, the scientific community simply discredited his entire idea.
Detailed explanation-2: -The drift according to him, might have occurred due to centrifugal forces of earth or astronomical changes. Continents could not possibly the way he described it because he did not provide any hard evidence that would give the ultimate cause or mechanism for the continents to move.
Detailed explanation-3: -Alfred Wegener proposed that the continents were once united into a single supercontinent named Pangaea, meaning all earth in ancient Greek. He suggested that Pangaea broke up long ago and that the continents then moved to their current positions. He called his hypothesis continental drift.
