Why did Alfred Wegener get criticism?

Answer 1

1) Most scientists did not believe Wegener's theory and thought it was foolish.] Some critics thought the old theories of giant land bridges could explain the similarities among fossils in South America and Africa. Others argued that Wegener's theory did not explain the forces that would have been needed to move continents to such great distances. Wegener thought that the forces that moved the continents could be the same forces that made earthquakes and volcanic eruptions.

Answer 2

Alfred Wegener received criticism for his theory of continental drift because he did not have a plausible mechanism to explain how continents could move across the Earth's surface. Additionally, his theory contradicted the prevailing understanding of geology at the time, leading many in the scientific community to reject it until the mechanism of plate tectonics was proposed and accepted.
