The major forces that form folded mountains are

Compression stress compresses rock.

Several mountains include enormous magnificent folds of rocks. Mountains that are accumulated primarily by gathering are described folded mountains. Compression stresses are a significant force that develops folded mountains.

Thrust faulting is also necessary for the development of folded mountains, which are often termed as fold-and-thrust belts. Folded mountains often carry various stacked pressure faults that have dismissed the folded rock layers near the northern Rocky Mountains. The Appalachian Mountains and the Alps in Europe are examples of folded mountain ranges
