Sorting (sediment) Sediment consisting of well sorted grains (left) compared with poorly sorted grains (right). Sorting describes the distribution of grain size of sediments, either in unconsolidated deposits or in sedimentary rocks. This should not be confused with crystallite size, which refers to the individual size of a crystal in a solid. Crystallite is the building block of a grain. Very poorly sorted indicates that the sediment sizes are mixed (large variance); whereas well sorted indicates that the sediment sizes are similar (low variance).
Silt is often found in river estauries, because the fine particles are washed downstream and deposited when the water flows more slowly. SAND is small pieces of rock (2mm to .05mm diameter) such as quartz or sandstone. Sand particles are large enough to allow water to drain easily, but they do not hold water and are easily blown around when dry. STONES, ROCKS AND BOULDERS are larger pieces of rock which are too big to form part of the soil but are found in many gardens. Under the surface layer of soil, they can help drainage. As well as rock, soil contains organic material, formed from decayed plants or animals.
