Scientists believe the Appalachian Mountain range--which extends from lower Maine to Georgia--were created when the Super Continent, Pangea, split apart millions of years ago. Scientists also believe the Appalachian Mountains once had volcanos.
Technically no, but the the supply of coal in the Appalachian mountains will rebuild itself over the millions of years that coal forms. Coal forms from the dead remains of once living organisms. Since the organism(s) aren't solid it will take millions of years for he coal o form a solid substance.

The Appalachian Region was formed in the Paleozoic era millions of years ago when the North American and African Tectonic Plates Collided.

The Appalachian Mountains are millions of years older than the Rocky Mountains. Geologists believe the Appalachian Mountains once had active volcanoes because of the types of rocks found but these went extinct long ago. Because of erosion, wind, and time, the Appalachian Mountains are now more rounded and less in height.
300 million years ago The Appalachian Mountain Range is estimated to be formed 300 millions years ago, when Pangaea was breaking off into Laurasia and converged further into Africa and North America.
the Appalachian mountains were formed about 165 million years ago
