The Appalachians are much older than the Rockies and so they are more worn. The Appalachians are about 300 million years old, while the Rockies are about 65 million years old. As a result, the Appalachians are more worn. The Appalachians formed as a result of a collision between continents that formed the supercontinent Pangaea. The Rockies formed as an oceanic plate slid under the North American Plate at a shallow angle, dragging against the base of the crust.

The Appalachian Mountains are older and have been subjected to more erosion, resulting in smoother, rounded peaks. The Rocky Mountains are younger, taller, and still have more rugged, sharp peaks due to ongoing tectonic activity. Additionally, the two mountain ranges formed under different geologic processes, with the Appalachians forming from continental collision and the Rockies forming from the uplifting of the North American Plate.
