Difference between western cordillera and the Appalachians?

Answer 1

the western cordilleras are young fold mountains, while the appalachians are old fold mountains.

Answer 2

The Western Cordillera and the Appalachians are both mountain ranges in North America, but they have distinct geological origins and characteristics. The Western Cordillera is a young, high, and rugged mountain range located along the western coast of North America, formed by the collision of tectonic plates. In contrast, the Appalachians are an older, lower, and more eroded mountain range located in the eastern part of North America, formed by a series of tectonic events over millions of years. Additionally, the Western Cordillera is associated with active tectonic processes such as earthquakes and volcanic activity, while the Appalachians are relatively stable and inactive in terms of tectonic activity.
