WebIn simple terms, faulting is when rocks break, and folding is when rocks bend. Rocks behave differently under pressure. If rocks are deep underground with lots of pressure on them … In structural geology, a fold is a stack of originally planar surfaces, such as sedimentary strata, that are bent or curved during permanent deformation. Folds in rocks vary in size from microscopic crinkles to mountain-sized folds. They occur as single isolated folds or in periodic sets (known as fold trains). Synsedimentary folds are those formed during sedimentary deposition.
