Sediments may include: fragments of other rocks that have been worn down into small pieces, like sand, organic materials, or in other words, the remains of once-living organisms, or chemical precipitates, which are materials that get left behind after the water evaporates from a solution. Most sediments settle out of water (Figure 4.11).
