This principle states that layers of rock are superimposed, or laid down one on top of another. The oldest rock strata will be on the bottom and the youngest at the top. Think about it like this: You have a ... There are many different names for mesas, including tables or plateaus. For the most part, mesas are found in areas with layers of sedimentary rock. Over millennia, water erodes away at the landscape, removing the more erosion-prone layers and leaving behind the more durable layers.In structural geology, a fold is a stack of originally planar surfaces, such as sedimentary strata, that are bent or curved ( "folded") 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 ).
