Bedding in sedimentary rocks is parallel to the attitude of the strata. Bedding that is oriented horizontally is called ‘horizontal bedding’. It indicates minimal movement of materials during sedimentation in a calm environment, and these conditions are common in sedimentary rocks (Fig. 19). For example, carbonaceous shale and black shale often have horizontal bedding. These rocks generally form in lacustrine or marine environments in quiet deep water. Some limestone strata also have horizontal bedding, which indicates that they are formed in a deep carbonate basin. High-quality bedding is present in many geoparks, resulting in distinctive natural scenery. For example, horizontal bedding is widespread in Yuntaishan Global Geopark. The Hukou Waterfall in Huanghe (Yellow River) was formed when the river cut through the horizontal bedding in Triassic rocks, resulting in a splendid landscape (Fig. 20).
