Completely unrelated. North and south america wern’t attached when the appalachians were tall. The Andes are formed by an ocean plate (the Nazca plate) dragging as it is sucked under south america. They are tall, and still growing taller.
No, the Andes are part of the American Cordillera, which also includes the Sierra Nevada and Sierra Madre and has to do with the Pacific Plate/Ring of Fire
Isn’t Appalachia part of the Andes too, or are they unrelated?

Unlikely, the Andes are newer.
