Deposition is the geological process in which sediments, soil and rocks are added to a landform or landmass. Wind, ice, water, and gravity transport previously weathered surface material, which, at the loss of enough kinetic energy in the fluid, is deposited, building up layers of sediment.
A diagram of various depositional environments. In geology, depositional environment or sedimentary environment describes the combination of physical, chemical, and biological processes associated with the deposition of a particular type of sediment and, therefore, the rock types that will be formed after lithification, if the sediment is preserved in the rock record.
Abyssal fan – Underwater geological structures associated with large-scale sediment deposition; Abyssal plain – Flat area on the deep ocean floor; Bench – Long, relatively narrow land bounded by distinctly steeper slopes above and below; Butte – Isolated hill with steep, often vertical sides and a small, relatively flat top

Sedimentary structures include all kinds of features in sediments and sedimentary rocks, formed at the time of deposition.. Sediments and sedimentary rocks are characterized by bedding, which occurs when layers of sediment, with different particle sizes are deposited on top of each other. [1]
The process of determining a specific date (in years or some other unit of time) for an archaeological, geological or paleontological site or artifact. accident A sudden discontinuity of ground, such as a fault of great thickness, bed or lentil of unstable ground. [1] accretion A process by which material is added to a tectonic plate or ...
Ripple cross-laminae forms when deposition takes place during migration of current or wave ripples. A series of cross-laminae are produced by superimposing migrating ripples. The ripples form lateral to one another, such that the crests of vertically succeeding laminae are out of phase and appear to be advancing upslope.
