The depositional slip-off slope is on the left and a small river cliff on the right. River Ashes Hollow, UK. Schematic cross section of a meandering river channel showing slip-off slope formation. A slip-off slope is a depositional landform that occurs on the inside convex bank of a meandering river.
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.
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.
Flat (landform) – Relatively level surface of land within a region of greater relief; Glen – Name for valley commonly used in Ireland, Scotland and the Isle of Man; Gully – Landform created by running water and/or mass movement eroding sharply into soil; Hill – Landform that extends above the surrounding terrain
Sediments underlying fluvial terrace exposed in cutbanks along the Manú River, Peru. In geology, a terrace is a step-like landform. A terrace consists of a flat or gently sloping geomorphic surface, called a tread, that is typically bounded on one side by a steeper ascending slope, which is called a "riser" or "scarp".
An alluvial plain is a plain (an essentially flat landform) created by the deposition of sediment over a long period by one or more rivers coming from highland regions, from which alluvial soil forms. A floodplain is part of the process, being the smaller area over which the rivers flood at a particular time. In contrast, the alluvial plain is ...
Sedimentation is the deposition of sediments. [1] It takes place when particles in suspension settle out of the fluid in which they are entrained and come to rest against a barrier. This is due to their motion through the fluid in response to the forces acting on them: these forces can be due to gravity, centrifugal acceleration, or ...
Fluvial terraces can be used to measure the rate at which either a stream or river is downcutting its valley. Using various dating methods, an age can be determined for the deposition of the terrace. Using the resulting date and the elevation above its current level, an approximate average rate of downcutting can be determined. [6]
