I want to know the answer to the following question:
The mountains forming to the southwest of the Appalachians in the Carboniferous are known as what?
All the background I'm provided with is that "This continental collision resulted in the Hercynian orogeny in Europe, and the Alleghenian orogeny in North America; it also extended the newly uplifted Appalachians southwestward as the Ouachita Mountains.". Is that enough to answer the question?
