Can rocks fold
WebIt is that process of folding in which the competent or stronger rocks are thrown into folds due to their sliding against each other under the influence of lateral compression. This is also distinguished as flexural-slip-folding in which the slip or movement of the strata involved takes place parallel to the bedding planes of the layers. WebFolds can occur in any type of rock and are often found as several connected bends. Answer Folds are secondary geologic structures that form due to bending or curving …

WebRocks deforming plastically under compressive stresses crumple into folds. They do not return to their original shape. If the rocks experience more stress, they may undergo more folding or even fracture. There are three major types of rock folding: monoclines, synclines, and anticlines.
