Can rocks fold
WebImagine that you are a geologlist looking at two different folds. You observe that in the first fold, the rocks get younger the farther they are away from the center of the fold. In … 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.
