I don't know, but it wasn't the cascades. HAHAHAHAHHA
The Appalachian Mountain Range was likely created before the continental separation around 350 million years ago. This mountain range formed during the assembly of the supercontinent Pangaea and has since been eroded down from its original size.

Some examples of mountain ranges created by continental-continental convergence are the Himalayas (resulting from the collision of the Indian and Eurasian plates) and the Alps (formed by the collision of African and Eurasian plates).
Both plates collide and lift upward, forming moutains or mountain ranges.
The Andes mountain range was not formed as a result of continental-continental convergence; instead, it resulted from oceanic-continental convergence. Specifically, the Andes were created by the subduction of the Nazca Plate beneath the South American Plate. In contrast, the Himalayas, Alps, and Appalachians are primarily the result of continental-continental tectonic interactions.
When two Continental plates collide, both plates lift upward and it can form mountains or mountain chains.
Converging continental plates create mountain ranges through a process called continental collision. When two continental plates collide, neither is subducted due to their similar density. Instead, the plates crumple and fold, leading to the uplift of the Earth's crust and the formation of mountain ranges.
Parallel belts of folded mountains and volcanic mountains
Landforms such as ocean trenches and mountain ranges are created.
When two continental plates converge, a major landform created is a mountain range. The intense pressure and collision between the plates causes the Earth's crust to uplift, forming large mountain ranges such as the Himalayas or the Alps.
Separation Anxieties was created in 2000.
The Final Separation was created in 1986.
