Best Answer

The mountains in Pennsylvania were formed millions of years ago through tectonic plate movements and the collision of continents. The Appalachian Mountains, which run through Pennsylvania, were created when the North American Plate collided with the African Plate. Over time, erosion and glaciation further shaped the mountains into their current form.
