Attrition (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 allows past and present geologic changes to be understood as well as paleogeomorphicLandforms of Coastal Deposition Coastal deposition is when the sea drops or deposits material This can include sand, sediment, and shingle, resulting in landforms of coastal Landforms of coastal deposition Internet Geography

Coastal landscapes are formed by a combination of erosion, transportation and deposition processes They each have distinctive features which can be identified on an OS map Part of GeographyAttrition: Waves smash rocks and pebbles on the shore into each other, and they break and become smoother Solution: Acids contained in sea water will dissolve some types of Coastal erosion Coastal processes CCEA GCSE Geography

Coastal erosion

Coastal erosion is the loss or displacement of land, or the longterm removal of sediment and rocks along the coastline due to the action of waves, currents, tides, winddriven water, waterborne ice, or other Coastal landforms Coastal landforms created by erosion include headlands, bays and cliffs Landforms created by deposition include spits, salt marshes and beaches Part of GeographyCoastal landforms Landforms created by erosion BBC

Coastal landscapes Features of coastal erosion BBC

Coastal Erosion Geological Survey of Ireland

Destructive waves erode through four main processes; Hydraulic Action, Compression, Abrasion and Attrition Image credit: Jeff Hansen, US Geological Survey Hydraulic Action Hydraulic Action is the sheer force of water crashing against the coastline causing material to be dislodged and carried away by the sea CompressionSo coastal abrasion is the wearing down and grinding down of a coast Abrasion occurs as breaking waves which contain sand and large fragments smash along the cliff and wear it away It is commonly known as the sandpaper effect Abrasion is when two surfaces rub against each other and attrition is where they bounce or smash against each otherCoastal Abrasion (or Corrosion) Geography Mammoth Memory

COASTAL EROSION Here we look at the different features of coastal erosion These being those that form together on headlands, for example, caves, arches, stacks and stumps We also look at the formation of bays and how they relate to headlands We look at the processes involved in coastal erosion and then have diagrams which help explain Coastal landforms created by erosion include headlands, Attrition waves cause the rocks to crash against each other, breaking them down into smaller and rounder piecesCoastal landforms Landforms created by erosion BBC

There are four wave erosion processes: Hydraulic action Corrosion Abrasion Attrition How these are influences by wave type, size and lithology They are most effective during high energy storm events with large destructive waves However, even coastlines composed of soft, unconsolidated sediment (eg boulder clay of Holderness Coast inDeflation: The removal of fine, loose particles from the surface of rocks Abrasion: Small particles being carried by the wind scrape of particles from the rock surface It then transports the eroded material by three processes: Suspension: Very small particles (<015mm) are picked up and carried by the windLandforms PartII दृष्टि आईएएस

There are four main processes of coastal erosion These are corrasion, abrasion, hydraulic action and attrition Corrasion is when destructive waves pick up beach material (eg pebbles) and hurl them at the base of Hydraulic power The movement of objects using liquids With the sea, this is the process by which breaking waves compress pockets of air in cracks in a cliff The pressure may cause the crack to widen, breaking off rock The water hydra nt could f lic k and power ( hydraulic power) away objects using waterHydraulic power Geography Mammoth Memory Geography

Abrasion The Geography Site

Abrasion ( Corrasion ) Abrasion occurs when particles of rock and sand grind down larger rocks and cliffs They act like sandpaper rubbing at the surface, removing tiny amounts but, as wave after wave hits the cliff base, throwing more and more sand at it, the abrasion becomes more pronounced Think of abrasion as tiny bits of rock in theAttrition 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 Attrition Geography tutor2u

Coastal Erosion is the wearing away of material by sea water There are 4 processes of erosion These are * Hydraulic action * Abrasion (sometimes called corrasion) * Attrition * Solution (sometimes called corrosion) What is Coastal Erosion? AnswersAttrition 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 nondramatic and dramatic erosion in regions where coastlines have fracture zones or rock layers with unstable erosion What is Attrition? Definition from Corrosionpedia

Coastal Processes ALevel Geography Marked by Teachers

Waves are formed by wind blowing on the surface of the sea This exerts drag or friction on the water, creating a swell in the water The wind and its energy cause water particles to rotate as the wind passes over The wave carries on moving but the water particle returns to its original positionAttrition occurs when rocks and pebbles carried by waves smash into each other, and against the seabed and the base of a cliff or rocky outcrop Through this action, the rocks and pebbles are worn away, becoming smaller, rounder and smoother Attrition rocks and boulders transported by waves bump in to each other and break in to smaller piecesAttrition Geography Mammoth Memory Geography
