The Anto Atlas Mountains of Morrocco in North Africa were also formed by the same processes that formed the Appalachians, seperated by continental drift. Is there any geological basis that the mountains of Scotland were formed by the same process? Because I don't thonk they were?
If I am remembering correctly, what today is known as the Appalachian Mountains was formed through five different orogenies. The different periods of mountain have created different "spurs" of the range in places such as North Africa, Scotland, Arkansas, and Oklahoma. Erosion and continental drift have since separated these different ranges.
