Who said nature does not make straight lines?

Have you ever wondered why some rocks appear to be cut intentionally? Faults and fractures exist in all kinds of rocks and they can be incredibly straight. Fracture is a general term for any type of surface along which rocks or minerals have broken. A fault is a specific type of fracture, where a displacement occurs between the cracked blocks. Examples of faults and fractures can be found in the Devil’s Punchbowl beach in Oregon Coast.  One photo shows a fault crossing 18 million-year-old sedimentary rocks – mostly made up of sand and silt. The other photo shows fractures cutting the top of a bedding surface of the same rock.
