Explanation / Answer
A main objection of Alfred Wegener's hypothesis was he couldn't provide a credible mechanism.
The flaws and defects in Wegner's theory of continental drift are as follows :
1. The forces applied by Wegener are not sufficient enough to drift the continents apart. He only pointed out about differential gravitational force and the force of buoyancy and tidal force of Sun and the Moon.
2. The concept of juxtaposition cannot be validated.
3. Wegener has not elaborated the direction and chronological sequence of the displacement of the continents.
