Fold mountains are formed by the folding and deformation of rock layers as a result of tectonic activity. Some of their characteristics include:
- Fold mountains have a long, linear shape, often stretching for hundreds of kilometers.
- They typically have a series of parallel ridges and valleys, with the ridges formed by the upfolding of rock layers and the valleys formed by the downfolding of rock layers.
- The rock layers in fold mountains are often highly folded and deformed, and may be tilted or overturned in some places.
