Often, this surface rock is limestone, which is easily eroded, or worn away, by the movement of water. In a landscape where limestone sits underneath the soil, water from rainfall collects in cracks in the stone. These cracks are called joints.Geological principles state that if a fragment of rock is included, that is entirely surrounded by rock, it must be older than the surrounding rock.
