Waves influence the beach, and tides shape the back-barrier. Wind transports sediment from the beach to the dunes, and sometimes into the back-barrier. High storm water carries sand from the beach and dunes into the back-barrier and lagoon, creating overwash deposits. Facies and Sediment Characteristics, in Stratigraphic OrderSediment is made up of loose particles of sand, silt and clay. It is a natural part of the Chesapeake Bay, created by the weathering of rocks and soil. In excess amounts, sediment can cloud the waters of the Bay and its tributaries, blocking sunlight for underwater grasses, covering bottom habitats (such as oyster beds) as it settles and ... The photos below in Figures 7.67, 7.68, and 7.69 show three examples. Most sandstones contain sand-sized (0.062 to 2 mm in longest dimension) quartz or feldspar grains. Coarser sandstones may contain both lithic fragments and individual detrital mineral grains. Sometimes clays or other minerals are present in a matrix between larger grains.water pollution.
