Where are the oldest mountains?

The Appalachian Mountains are widely regarded as the oldest mountain range in the world. Located primarily in the eastern part of North America, they stretch for over 1,500 miles from Alabama in the south to Newfoundland and Labrador in Canada. The formation of the Appalachian Mountains can be traced back over 480 million years to the Precambrian era. They were created as a result of continental collisions and orogeny, involving the collision of the North American and African plates. The mountains have been subjected to erosion and other geological processes over millions of years, resulting in their gradual weathering and the formation of valleys and plateaus. Despite their ancient origins, the Appalachian Mountains are not as high as some younger mountain ranges, with Mount Mitchell in North Carolina being the highest peak at 6,684 feet.
