Folds

Folds are bends or twists in the Earth's crust caused by tectonic forces, similar to how a rug might crease when pushed. When rocks are subjected to pressure over long periods, they bend rather than break, creating layered structures called folds. These features are common in mountain ranges and provide insights into the Earth's geological history. Folds can vary in size, from small, tight bends to large, gentle waves, and are important for understanding regions' structural stability and natural resource locations.
