They're on the north American plate.
The pacific plate and the cocos plate
No, the Andes are near a subduction zone type plate edge but the Appalachian Mountains are not near any plate edge of any kind.
Appalachian Mountains
No. There is no such thing as a passive plate edge. They are near a passive continental margin.
The Appalachian mountains were formed by the collision of the North American plate and the African plate during the formation of the supercontinent Pangaea. This collision resulted in the uplift and folding of the crust, creating the mountain range.
The Appalachian mountains were formed as a result of a collision between the North American plate and the African plate during the Paleozoic era. This collision caused the uplift and folding of rocks that eventually formed the mountain range we see today.
The remains of the mountains exposed are marine sedimentary rocks, oceanic basalt, even coal.
the Atlantic plate sliding under the north American plate over 300 million years ago
The Appalachian Mountains run through Pennsylvania, creating a range of peaks across the state. These mountains were formed millions of years ago through tectonic plate movements and erosion processes.
Appalachian Mountains: Formed when the North American Plate collided with the African Plate. Himalayas: Created by the collision of the Indian Plate with the Eurasian Plate. Andes Mountains: Resulted from the subduction of the Nazca Plate beneath the South American Plate. Alps: Formed where the African Plate collided with the Eurasian Plate.
