Folding is a process in geology where rock layers are bent or curved due to tectonic forces. This deformation can occur over millions of years as the Earth's crust shifts and moves. Folding can result in various types of structures, such as anticlines, synclines, and monoclines, which are important in understanding the geological history of an area. **
