When did the Appalachian Mountain Range begin to form? a date or time in history would be helpful.
Thank you.

These mountains formed with the collision of the early Africa continent into North America about 360 million years ago. This huge collision rippled the land well into Missouri, but created the App. mountains. They were much taller at first, but erosion has taken a toll on this chain and they are well on their way of being worn away.

You need to look this up in a library. the information is well presented in a number of references. Sds
