During Wegener’s time, what was unknown to scientists was that Earth’s crust is made of plates that move. Although Wegener proposed the idea of continental drift based on the fit of coastlines and the distribution of fossils, the concept of plate tectonics and the actual mechanisms behind the movement of the Earth's crust were not understood until later.
