What is hydraulic action attrition?
Hydraulic action – this is the sheer power of the waves as they smash against the cliff. Air becomes trapped in the cracks in the rock and causes the rock to break apart. Attrition – this is when rocks that the sea is carrying knock against each other. They break apart to become smaller and more rounded.
What is abrasion attrition and hydraulic action?
Hydraulic action – This is the sheer power of the water as it smashes against the river banks. 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 are the 4 processes of erosion?
Destructive waves erode through four main processes; Hydraulic Action, Compression, Abrasion and Attrition.
What is the process of hydraulic action?
Definition. Hydraulic action refers to the physical weathering and mechanical response of earth materials to flowing water in rivers and streams or breaking waves and storm surge along shorelines. Physical weathering by flowing water is a rock-water interaction phenomenon (Keaton, 2013).
What is the difference between corrosion and corrasion?
As nouns the difference between corrosion and corrasion is that corrosion is the act of corroding or the condition so produced while corrasion is wear caused by wind-blown or water-borne sand.
What are the 3 coastal processes?
The three principle marine processes that influence coasts are erosion, transportation and deposition.
What is the difference between corrosion and abrasion?
Corroded parts show even wear, while abrasion causes uneven wear of a mechanical implement. Both abrasion and corrosion can be reduced by coating a surface with a resistant material.
What are the 6 process of erosion?
Erosional processes along coastlines include: (1) the direct effects of hydraulic action, wedging, and cavitation by waves; (2) abrasion (corrasion), using sand, gravel, and larger rock fragments as tools; (3) attrition of the rock particles themselves during this abrasive action; (4) salt weathering or fretting; (5) …
What are the 5 processes of erosion?
There are five main processes which cause coastal erosion. These are corrasion, abrasion, hydraulic action, attrition and corrosion/solution. Corrasion is when waves pick up beach material (e.g. pebbles) and hurl them at the base of a cliff.
What is the process of hydraulic action in a river channel?
is the erosion that occurs when the motion of water against a rock surface produces mechanical weathering. It is a mechanical process, in which the moving water current flows against the banks and bed of a river, thereby removing rock particles. …
