Why are the Appalachian Mountains and the Rockey Mountains different?
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.
Why are the Appalachians smaller than the Rockies?
When the Supercontinent broke apart, the Appalachian Mountains were forming. Their formation was part of the tetonic plate activity going on at that time, and scientists believe the Appalachians once had active volcanos. So the Appalachian Mountains are millions of years older than the Rocky Mountains in the west. Therefore, the Appalachians have also had millions of years of erosion; though still having high elevations, they are more much more rounded than the Rocky's peaks, and have lush valleys surrounding the Appalachians.
