The Andes, Himalayas, and Appalachian Mountains were all formed through tectonic processes, specifically the collision and interaction of tectonic plates. The Andes were primarily shaped by the subduction of the Nazca Plate beneath the South American Plate, while the Himalayas resulted from the collision of the Indian Plate with the Eurasian Plate. The Appalachian Mountains, in contrast, were formed much earlier through a combination of continental collision and volcanic activity during the Paleozoic era. Despite their different geological histories and ages, all three ranges exemplify the dynamic nature of Earth's crust and the forces of plate tectonics.
Scientists can determine the relative timing of mountain formation through methods like radiometric dating of the rocks that make up the mountains. By dating the age of the rocks in the Appalachian Mountains and the Himalayas, scientists have been able to determine that the Appalachians were formed much earlier, around 480 million years ago, while the Himalayas began forming around 50 million years ago.

The Appalachian Mountains were formed in a Constructive Force
the Appalachian mountains were formed about 165 million years ago
The Himalayas are known to be youngfold mountains. Young, because these have been formed relatively recently in the earth's history, compared to older mountain ranges like the Aravallis in India, and the Appalachian in the USA. They are known as fold mountains because the mountains extend for 2500 km in length in a series of parallel ridges or folds.
