What is Abrasion?
The abrasion process is characterized by surfaces sustaining damage when in motion. Friction is the primary cause of this problem, and erosion describes the process in question. It is a slow process that takes a considerable amount of time. Scuffing or scratching is a form of abrasion that occurs when two surfaces brush against one another.
The number of different factors determines how two surfaces are abraded. Among the many considerations is the surface’s composition in terms of its mass, density, velocity, and roughness. Abrasion occurs faster when the materials are lightweight and loosely arranged in a structure. On the other hand, a bruise appears very slowly if the materials are heavy, hard, and closely packed.
Abrasion can occur on a single surface or with multiple characters simultaneously. Construction industries have been known to carry out the process in a deliberate and regulated manner at times. However, they can be classified into four major types when they occur naturally: air abrasion, coastal abrasion, glacial, and channel transfer. Wind abrasion is the most common type of abrasion.
Wind abrasion happens when little stones and sand scrape against surfaces as the wind carries them to their destination. Coastal abrasion occurs as a result of things moving through the water. Glaciation is the result of ice rubbing up against rock surfaces. Finally, as things flow along river channels, this is called channel transport.
What is Attrition?
Attrition is a natural phenomenon that occurs most frequently in regions where there are bodies of water present, and it should not be confused with coastal abrasion, a different sensation. A process known as attrition occurs when surfaces collide, causing them to shatter or wear down. In contrast to attrition, the procedure is relatively swift, and there is no friction in this process.
Riverbed attrition serves as a great illustration of this concept. The firm sediments that make up the bottom of a river’s surface are composed of a range of different types. While this is true when other hard objects flow with the current of water, they have a strong tendency to strike the bottom of the pool. When this happens, there is a certain amount of environmental damage.
Several distinct factors influence the extent of the damage. In the case of rock with existing cracks, if another rock collides with it, the disadvantage to that particular rock will be significantly increased. However, if a soft object strikes the same stone, the resulting damage would be minimal.
Regardless, a slew of methods has been devised by humans to maintain control over the process. One of these structures is a seawall. The solids that are carried by water are filtered away at an early stage due to this filtering.
Difference Between Abrasion and Attrition
- Wear and tear caused by sediment transport are characterized as abrasion, whereas attrition reduces the amount of material moved during erosion.
- Surfaces are subjected to abrasion over a lengthy period, whereas attrition occurs quickly.
- While the impact of surfaces induces both abrasion and attrition, the bruise is mostly caused by the friction between characters in motion.
- In contrast to abrasion, attrition is determined by the shape, size, toughness, fractures, & porosity of the surface’s materials. Abrasion is impacted by the materials’ density, mass, velocity, and roughness on the surface.
- Generally speaking, abrasion can be observed in several locations where rocks & other sediments are present.
Comparison Between Abrasion and Attrition
|Parameters of Comparison
|Due to the movement of silt, abrasion is a process of decomposition.
|Particles are reduced by attrition during erosion.
|For surfaces to go through this process, it takes a long period
|The procedure is fast and efficient.
|In motion, surfaces rub against one another, resulting in this.
|It is the result of surfaces crashing together.
|These factors are interrelated and determine how the surface feels under your feet.
|Because of its shape and size, hardness and porosity are also factors.
|It is possible for abrasion to occur anywhere there are rocks or sediments.
|Areas with waterbodies have a higher rate of attrition.
