The Appalachian Mountains were once part of a landmass near modern-day Africa during the formation of the super continent Pangaea.

During the Paleozoic Era, the Appalachian Mountains were formed when the North American continent collided with other landmasses, including the one that is now Africa. These landmasses were once part of a supercontinent known as Pangaea. The collision of tectonic plates during this period led to the uplift of the Appalachian Mountains, which are considered to be some of the oldest mountain ranges in the world. Over time, as Pangaea broke apart, the continents drifted to their current positions, separating the Appalachian Mountains from Africa, but the geological connection remains in the structure of the range.
