During Wegener’s time, what was unknown to scientists is that Earth’s crust is made of plates that move. Wegener proposed the theory of continental drift based on evidence such as the fitting coasts of continents, aligned mountain ranges, and similar fossils found in different regions, but the concept of tectonic plates and their movement was not fully understood until later.
