Fold Mountains: Formation

Where are fold mountain ranges found on our planet? And how do the movements of tectonic plates affect their growth? Earth Science - Geology - Learning Points. A Fold mountain forms over millions of years by a process called orogeny. Orogeny begins as two tectonic plates move toward each other and push together along their margins. Subduction occurs when sedimentary rock at the margins of the one of the tectonic plates folds upwards, as the other is forced underneath. At 8850m, Mount Everest is the highest fold mountain on Earth and is still growing. A Twig Curriculum Film. Delivering key learning points.
