Geology Solid fragmented material, such as silt, sand, gravel, chemical precipitates, and fossil fragments, that is transported and deposited by water, ice, or wind or that accumulates through chemical precipitation or secretion by organisms, and that forms layers on the Earth's surface. The sediment cell concept (sources, transfers and sinks) is important in understanding the coast as a system with both positive and negative feedback, it is an example of dynamic equilibrium. Figure shows the sediment cell as the graph of a calculated system, with inputs (sources), moves (streams) and stores (sinks). allogenic, allochthonous - Geological material that has been transported and then accumulates elsewhere is allochthonous, and sediment carried by a river is allogenic. Waves approach the coast at an angle because of the direction of prevailing wind. Lithification is how soft sediments, the end product of erosion, become rigid rock ("lithi-" means rock in scientific Greek).It begins when sediment, like sand, mud, silt and clay, is laid down for the last time and becomes gradually buried and compressed under new sediment. Sediments can be defined as fragments of organic or inorganic material that have been broken down. The physics of the most common sedimentation process, the settling of solid particles from fluids, has long been known.

They are often determined by the topography and shape of the coastline which directs the movement of the sediment within the cell. Angle of Dip: the angle of the bedding planes which affects the shape of the cliff. Sediment is moved up and down the beach, but there is no net lateral movement. Sediment cells are areas along the coastline and in the nearshore area where the movement of material is largely self-contained. It can be as small as a grain of sand or as large as a boulder.
