Outline how a fold mountain is formed

Answer Text:
- Extensive shallow depressions called geosynclines develops.
- Sediments from higher grounds are deposited in the geosyncline.
- Internal forces cause the crust on either side of the geosyncline to move towards the geosyncline.
- As a result, the sediments are compressed and form folds which rise above sea level.
- The process continues and eventually the rocks or sediments become so intensively folded to form high mountains.
