Voges Mountain is the example of a mountain that is not a fold mountain.
Fold mountains are mountains that are formed when two tectonic plates collide with each other, causing the rocks on the edges to crumple and fold. This folding process results in the formation of long, linear mountain ranges with parallel ridges and valleys, such as the Himalayas, Rockies, and Andes.
The Vosges Mountains, on the other hand, are not fold mountains. They are actually part of the Vosges and Palatine Forests, a range of low mountains located in northeastern France and southwestern Germany. The Vosges Mountains were formed through a different geological process called rifting, which occurs when the Earth's crust stretches and thins, leading to the formation of a series of block mountains.
In summary, while the Himalayas, Rockies, and Andes are all examples of fold mountains, the Vosges Mountains are not.
