What does corrasion mean in geography?
Corrasion – wearing away of the river bed and banks by the load hitting against them. Attrition – wearing down of the load as the rocks and pebbles hit the river bed and each other, breaking into smaller and more rounded pieces.
What is the meaning of corrasion?
A process of erosion, corrasion refers to the strictly mechanical wear of bedrock by moving detrital and other materials during (a) their migration downslope under the influence of gravity, and (b) their further transportation by erosional agencies such as running water, moving ice, or wind.
What is corrasion with an example?
An example is the wearing away of rock on a river or seabed by the impact or grinding action of particles moving with the water.
What is corrasion in wave erosion?
Corrasion is when waves pick up beach material (e.g. pebbles) and hurl them at the base of a cliff. Abrasion occurs as breaking waves which contain sand and larger fragments erode the shoreline or headland. It is commonly known as the sand paper effect. When waves hit the base of a cliff air is compressed into cracks.
What is corrasion or abrasion?
corrasion. / (kəˈreɪʒən) / noun. erosion of a rock surface by rock fragments transported over it by water, wind, or iceCompare abrasion (def.
Are abrasion and corrasion the same thing?
Abrasion (also called corrasion , is the process of rocks and pebbles carried by the waves wearing away rocks as they are thrown against cliffs.
What is corrasion and abrasion?
abrasion (corrasion) The erosive (see EROSION) action that occurs when rock particles of varying size are dragged over or hurled against a surface. Some common agents of abrasion are the bed load of streams, rock debris embedded in the bases of glaciers, and sand and shingle transported by wind or waves.
Are abrasion and corrasion the same?
Abrasion. Abrasion (also called corrasion , is the process of rocks and pebbles carried by the waves wearing away rocks as they are thrown against cliffs.
Is attrition the same as corrasion?
Abrasion/Corrasion – the force of the water in the river carrying stones and other materials grinds the bedload like a piece of sandpaper. Attrition – rocks being carried by the river smash together and break into smaller, smoother and rounder particles.
What is abrasion in weathering?
Rocks break down into smaller pieces through weathering. Rocks and sediment grinding against each other wear away surfaces. This type of weathering is called abrasion, and it happens as wind and water rush over rocks. The rocks become smoother as rough and jagged edges break off.
Is corrasion an abrasion?
What is traction in river transportation?
Definition: Traction is a method of transportation for large stones or boulders in a river. The stones are rolled along the river bottom by the water as they are too large to transport in the water. Traction.

What is abrasion in geography rivers?
Abrasion – When pebbles grind along the river bank and bed in a sand-papering effect. Attrition – When rocks that the river is carrying knock against each other. They break apart to become smaller and more rounded.
What is abrasion in geography glacier?
As a glacier flows downslope, it drags the rock, sediment, and debris in its basal ice over the bedrock beneath it, grinding it. This process is known as abrasion and produces scratches (striations) in bedrock surface.
