During Wegener's time, what was unknown to scientists was that Earth’s crust is made of plates that move. While Wegener proposed the theory of continental drift and presented evidence such as the fitting of coastlines and similar fossils on different continents, the concept of plate tectonics and the understanding that the Earth's crust is divided into moving plates were developed later, in the mid-20th century.
