The document discusses various processes of deposition. It explains that deposition is the settling out of particles and fragments from a transporting medium such as water or wind. Factors that affect deposition rates include particle size, shape, and density as well as the velocity of the transporting medium. Sorting processes like horizontal and vertical sorting can result in graded bedding. Erosional-depositional systems, like stream or glacial systems, involve the transformation of energy as material is transported, eroded, or deposited. Coastal deposition is influenced by ocean waves and currents.
