During Wegener’s time, scientists did not understand that the Earth’s crust is made of plates that move. This concept, which is fundamental to the theory of plate tectonics, was developed and widely accepted only later. Wegener proposed the idea of continental drift based on observations like the fitting of coastlines, aligned mountain ranges, and fossil distribution, but he did not have the mechanism of plate movement to support his theory.
