Quizplus · Accepted Answer

The Appalachians were formed by a series of collisional orogenies, which occurred during the Paleozoic era. These events involved the collision of several tectonic plates, including Laurentia, Baltica, and Avalonia, which eventually led to the formation of the supercontinent of Pangaea. The three phases of the Appalachian orogeny are the Taconic, Acadian, and Alleghenian orogenies.
