Summary

Folding is the bending of crustal rocks by compressional forces. An upfold is an anticline and a downfold a syncline. Folds range from symmetrical through asymmetrical, overfolds and isoclinal to recumbent and nappe, according to how intense the compression is. The chief resulting feature is a fold mountain.
