Fold Mountains

Mode of Formation

Fold Mountains are formed by large scale horizontal earth movement as a result of stress and compressional forces which cause the expansion or contraction of some parts of the earth. The compressional forces produce wrinkling or folding of the crust of the earth. The up folds of the wrinkles are anticlines while the down folds are called syncline.
