Fold mountains are mountains that form mainly by the effects of folding on layers within the upper part of the Earth's crust.
Before either plate tectonic theory developed, or the internal architecture of thrust belts became well understood, the term was used for most mountain belts, such as the Himalayas.
The Himalayas are a prime example of how tectonic plate motion can manipulate the earth in extraordinary ways.
These colliding plates resulted in the formation of the highest mountain range on the planet.
Our continents are carried by a series of tectonic plates located in the earth's lithosphere.
Earth's crust itself is warped into folded forms. Foldmountains are often associated with continental crust.
