Attrition is when sediment particles knock against the bed or each other and break, becoming more rounded and smaller as you move down the river. Find out more about river erosion
Attrition is the process of erosion that occurs during rock collision and transportation. The transportation of sediment chips and smooths the surfaces of bedrock; this can be through water or wind. Rocks undergoing attrition erosion are often found on or near the bed of a stream. Attrition is also partially responsible for turning boulders into smaller rocks and eventually to sand Attrition. Erosion that happens when rocks and boulders which have already been loosened from the coastline are ground over each other in the water - usually by repeated swash and backwash - and over time the angular edges become smoothed and rounded and boulders/fragments become pebbles, pebbles become shingle, and shingle may become sand . is the wearing away of rock along the coastline. Destructive waves are responsible for erosion on the coastline. There are four types of erosion: Hydraulic action - this is the. ADVERTISEMENTS: This article throws light upon the four mechanism of wave motion. The ways are: 1. Corrasion 2. Attrition 3. Hydraulic Action 4. Solvent Action. Way # 1.

An issue that every company deals with is attrition. Sales being an especially high attrition function makes this analysis paramount. Sales attrition is a result of several components including unoptimized sales compensation, unrealistic quotas, ineffective mentoring, career-path ambiguity, training inefficacy or just bad recruiting Attrition is where material transported by a wave is eroded through collision with other load items. It breaks down sediment into smaller sized particles, and the repeated collision blunts any of the particles' sharp edges, making the sediment increasingly rounded. Even harder rocks, such as quartz and granite form larger rounded shingle pebbles Attrition is a destructive process that wears away coastal regions. In this process, waves and other activities cause pebbles and rocks to bump against each other, resulting in fragmentation. Attrition can produce both non-dramatic and dramatic erosion in regions where coastlines have fracture zones or rock layers with unstable erosion resistance As we have noted already the processes and interaction of the river with its physical environment changes ast it flows from source to mouth.

Erosion also breaks up the rocks that are carried by the river. There are four types of erosion: Hydraulic action - This is the sheer power of the water as it smashes against the river banks. Air. Erosion refers to the wearing away of the land surface and removal of materials by river and seawater, ice and wind. There are four main processes of erosion along the coast. These are hydraulic action, abrasion and corrasion, attrition and solution. Hydraulic action. Waves breaking at the foot of a cliff force air in cracks to be compressed
The four main types of river erosion are abrasion, attrition, hydraulic action and solution. Abrasion is the process of sediments wearing down the bedrock and the banks. Attrition is the collision between sediment particles that break into smaller and more rounded pebbles. Hydraulic action is the force of water against the banks compressing air. Attrition is a related process wherein rocks carried by waves hit and break each other into smaller pieces. Hydraulic action simply refers to the force when waves impact the surface of a rock. This can trap air inside, which can slowly break apart the material from within. Solution occurs when seawater can dissolve some types of rocks by itself

The action of wind is dominant in desert and other semi arid regions of the world. Desert which are associated with aridity (dryness) are caused by low rainfall, high temperature, cold current and high evaporation rate. Deserts do experience cold currents. Deflation: This is the lifting and blowing away of loose sand and pebbles by wind Plus there are ideas for making geography models that make learning about coasts fun.

Headlands are land bordered by either salt or fresh water on three sides; these lands are referred to as capes. Bays are made up of soft rocks while headlands are made up of hard rocks. Bays are water bodies located on a land next to the sea or a lake located between two headlands. Bays are usually formed where weaker rocks like clay and sand.

Erosion is destructive waves wearing away the coast. There are four main processes which cause coastal erosion. These are corrasion/abrasion, hydraulic action, attrition and corrosion/solution. Corrasion/abrasion is when waves pick up beach material (e.g. pebbles) and hurl them at the base of a cliff. When waves hit the base of a cliff air is.
Wooden groynes are a common site on beaches on the UK and Europe. Simple to construct, and reasonably cheap for a form of hard engineering, they are normally installed as groups rather than as a single groyne. The length and spacing between the groynes is determined by the force of the waves, the strength of the longshore drift, and the amount. attrition; and; corrosion. Hydraulic action. The pressure of water breaks away rock particles from the river bed and banks. The force of the water hits river banks and then pushes water into cracks. Air becomes compressed, pressure increases and the riverbank may, in time collapse Attrition or losses from the health workforce exacerbate critical shortages of health workers and can be a barrier to countries reaching their universal health coverage and equity goals. Despite the importance of accurate estimates of the attrition rate (and in particular the voluntary attrition rate) to conduct effective workforce planning, there is a dearth of an agreed definition. Wave Cut Notch. This is simply a groove, notch or indentation formed along the base of a cliff when it is undercut by the sea. It occurs where the waves break against the cliff and where erosion is most powerful. The photograph shows a wave cut notch being formed at the base of a chalk cliff. The waves can erode only the parts of the cliff that.

Intense wave erosion causes the formation of a notch at the base of some cliffs. These are known as 'wave-cut notch' which mark the initial stages of under-cutting that leads to a mass movement as the cliff breaks away above the notch and falls into the sea. Other minor erosional features associated with cliffs are the stacks, sea caves and. . It affects boulders and stones that have already been eroded from the coast. Corrosion (solution) - occurs when rocks are dissolved by sea water This coloured diagram of Geographical abrasion is a great illustration to use on abrasion worksheets, posters and other teaching materials.

This Geography illustration of abrasion can be used for lots of. Attrition: Beach material is knocked together in water reducing their size and increasing their roundness & smoothness. Corrosion 1: Carbon dioxide in the atmosphere is dissolved into water turning it into a weak carbonic acid. Several rocks (e.g., Limestone) are vulnerable to this acidic water and will dissolve into it Erosion Processes. Hydraulic Action: pressure/force of the water loosening material & widening cracks in the river bank.; Abrasion: the scraping action of material being transported.; Attrition: the breaking of stones when they collide with other material.; Corrosion: the dissolving of rock (limestone etc) by acid in the water.; Erosion occurs more in the upper course than the lower course
The coast is the land along a sea. The boundary of a coast, where land meets water, is called the coastline. Waves, tides, and currents help create coastlines. When waves crash onto shore, they wear away at, or erode, the land. But they also leave behind little parts of the sea, such as shells, sand dollars, seaweeds, and hermit crabs 1. Erosional Topographies: (a) Gorge: A narrow valley between hills or mountains, typically with steep rocky walls and a stream running through it. (b) Canyon: Canyon is a narrower and deeper valley as compared to a gorge. (c) Waterfall: Waterfall is formed by sudden and rapid fall of water upon a steep slope
