Submarine sediment gravity flows
On the continental slope, erosion of the ocean floor to create channels and submarine canyons can result from the rapid downslope flow of  sediment gravity flows, bodies of sediment-laden water that move rapidly downslope as  turbidity currents. Where erosion by turbidity currents creates oversteepened slopes it can also trigger underwater landslides and debris flows. Turbidity currents can erode channels and canyons into substrates ranging from recently deposited unconsolidated sediments to hard crystalline bedrock. Almost all continental slopes and deep ocean basins display such channels and canyons resulting from sediment gravity flows and submarine canyons act as conduits for the transfer of sediment from the continents and shallow marine environments to the deep sea. Turbidites, which are the sedimentary deposits resulting from turbidity currents, comprise some of the thickest and largest sedimentary sequences on earth, indicating that the associated erosional processes must also have played a prominent role in earth's history.

''These are present at a great range of scales and they arise in a number of quite different ways: for example, by fluvial incision and subaerial erosion (above sea level); submergence of nonmarine or shallow-marine sediments during transgression (flooding surfaces and drowning unconformities), in some cases with shoreface erosion (ravinement); shoreface erosion during regression; erosion in the marine environment as a result of storms, currents, or mass-wasting; and through condensation under conditions of diminished sediment supply (intervals of sediment starvation).

The main attribute shared by virtually all of these discontinuities, independent of origin and scale, is that to a first approximation they separate older deposits from younger ones. The recognition of discontinuities is therefore useful because they allow sedimentary successions to be divided into geometrical units that have time-stratigraphic and hence genetic significance."''





Types and classification
A dozen or so common types of sedimentary basins are widely recognized and understood as distinct kinds of sedimentary basins that formed in particular ways. However, no single overall classification scheme for sedimentary basins is recognized as a standard, although several schemes have been proposed. Most classifications are based on one or more of these interrelated criteria:
 * Plate tectonic setting - the proximity to a plate tectonic boundary and the origin of the tectonically-induced forces that caused a basin to form
 * Nature of underlying crust - basins formed on Continental crust are quite different from those formed on Oceanic crust as the two types of Lithosphere have very different mechanical characteristics (rheology)
 * Geodynamics of basin formation - the mechanical and thermal forces that cause lithosphere to subside and form a basin
 * Petrolem/economic potential - basin characteristics that influence the likelihood that the basin has accumulations of petroleum

Although no one basin classification scheme has been widely adopted, several common types of sedimentary basins are widely accepted and well understood:
