Attrition and Detrition are the same and they mean wearing away of the the surface by scratching, cutting etc. This is usually in context with the river valley.
Abrasion is the reduction in size of rocks when they collide either among themselves or with the side walls of the valley. So this is context with the rocks.
Corrasion is the mechanical erosion of rocks by water while they move in water.

Abrasion refers to the wearing down of surfaces through friction caused by particles or materials rubbing against them, while corrasion specifically refers to the erosion caused by the grinding action of sediment particles carried by water, ice, or wind against surfaces like rocks and soil. In other words, corrasion is a type of abrasion that is primarily driven by the movement of material transported by fluids or wind.

Corrasion or abrasion take place
Abrasion is the mechanical wear caused by improper toothbrushing or other habits, mainly on the facial surface. Attrition is mechanical wear from the forces of mastication on the incisal or occusal surfaces
attrition, abrasion, hydraulic action, corrosion and erosion.
The four processes of marine erosion are hydraulic action (pressure from water), abrasion (wearing down of rocks by sediment), attrition (rock particles colliding and breaking down), and corrosion (chemical dissolution of rocks).
The smoothness of a shell found at the beach is most likely due to the processes of abrasion and attrition. Abrasion occurs when the shell is repeatedly tumbled and rubbed against other materials like sand and rocks. Attrition happens as the shell fragments break and wear down over time from these interactions, resulting in a smoother surface.
Three types of erosion that can affect a river valley are hydraulic action, abrasion, and attrition. Hydraulic action refers to the force of moving water eroding the river banks, abrasion is the process of rocks and sediment in the water wearing away the riverbed, and attrition occurs when rocks in the river collide, break down, and become smoother over time.
Rock sculptures are formed mainly by wind in the deserts. Aeolian processes and activities such as Deflation, Abrasion and Attrition are responsible for the desert landforms.
Abrasion is where flowing water picks up rocks and moves them along in it's current. It can cause damage to the side of rivers (Lateral Erosion) as well as the riverbed (Vertical Erosion). Abrasion can also be defined a lot simpler by just saying "When waves throw rocks up at cliffs" etc. This is not to be confused with Attrition though.
