Well-sorted sediment is a deposit in which the particles are of relatively uniform size, often resulting from the action of wind or water that selectively transports and deposits particles of similar size. Well-sorted sediments are significant in sedimentology for understanding the energy conditions of depositional environments, the processes of sediment transport, and the formation of sedimentary structures.
