Quizplus · Accepted Answer

The formation of the early Appalachian Mountains began during the Paleozoic era, specifically during the Ordovician period about 480 million years ago. This was due to the collision of the North American and African plates, which created a major mountain-building event known as the Taconic orogeny. The mountains continued to grow and erode throughout the Paleozoic era, with additional mountain-building events occurring during the Devonian, Mississippian, and Permian periods.
