Last I checked, the process was wind erosion. Water may have also played a role, but in a mountain range when it becomes more rounded, rather than jagged, it is usually wind erosion. the Appalachian Mountains are also hypothesized to be older than the Rockie Mountains therefore, having more time to wear away.

mostly erosion if u dont know want that is i when things on earth causes things to changt
The Tigris and Euphrates Rivers, which washed down fertile soil from the mountains, providing the basis for thriving agriculture which underpinned the resources necessary for civilisation to develop.
They're worn down from mountains and volcanoes.
The process that breaks down granite into sediments is weathering.

The Appalachian Mountains in Tennessee are in the Eastern part of the state only they are called "The Great Smoky Mountains."
Geologically speaking the Appalachians are older. The Rockies are an example of geological upheaval, while the Appalachians used to be a solid plain millions of years ago and eroded to become the mountains we have today.
The natural processes of water and wind erosion tend to wear down mountains.
The Rockies and the Appalachians are similar geologically (although the Appalachians are a little more diverse) however the Appalachians were emplaced a lot longer ago and have been exposed at the surface longer and therefore are more eroded down. By contrast the Rockies are still quite young (they were pushed up roughly in the Cretaceous, probably 100-200 million years after the Appalachians) and haven't been weathered down very much yet.
The Appalachians have been worn down by millions of years of weathering and erosion.

In general, the younger the mountain chain, the taller it is. Plate tectonics builds mountains by thrusting the crust upward, while erosion wears them back down over millenia. So the Himalayas are a new (and in fact, still growing) mountain chain, while the Appalachians are one of the oldest chains still identifiable as mountains.

because they have been worn down by approximately 250 million years of weathering and erosion. -Star
