Both abrasion and attrition refer to the wearing down of an object. ... However, attrition refers to the breaking off of particles (erosion) which occurs as a result of objects hitting against each other. Abrasion leads to surface-level destruction over time, whereas attrition results in more change at a faster rate.

Are abrasion and attrition the same thing?
Abrasion - this is when pebbles grind along a rock platform, much like sandpaper. ... Attrition - this is when rocks that the sea is carrying knock against each other. They break apart to become smaller and more rounded. Solution - this is when sea water dissolves certain types of rocks.
What is the difference between abrasion and erosion?
Abrasive wear is the loss of material by the passage of hard particles over a surface. Erosive wear is caused by the impact of particles against a solid surface.
What is abrasion process?
Abrasion is the physical process of rubbing, scouring, or scraping whereby particles of rock (usually microscopic) are eroded away by friction.
What is abrasion in a river?
Definition: Abrasion is a process of erosion which can happen in four different ways. ... Flowing water hits the channel walls and causes erosion. Pebbles or stones in the river also cause erosion when they hit the channel walls. The third type of abrasion is through the action of waves.
What does attrition mean?
The term attrition refers to a gradual but deliberate reduction in staff numbers that occurs as employees retire or resign and are not replaced. ... Attrition happens for several reasons, including pay, lack of growth, and poor workplace conditions.
What does abrasion mean?
1 : wearing, grinding, or rubbing away by friction. 2a : the rubbing or scraping of the surface layer of cells or tissue from an area of the skin or mucous membrane also : a place so abraded. b : the mechanical wearing away of the tooth surfaces by chewing. More from Merriam-Webster on abrasion.
What are the two types of abrasion?
Abrasion may be classified as flat abrasion, edge abrasion or flex abrasion. Abrasion resistance can be seen is the capacity to absorb energy. It is the ability to resist wear from the continuous rubbing of fabric against another surface.
What is an example of abrasion?
A scraped knee is an example of an abrasion. Other examples include road rash, raspberries, strawberries, and injuries such as a cheese grater or sandpaper could create.
What does tooth abrasion look like?
Tooth wear from abrasion typically looks like a wedge or V-shaped indentation of the tooth at the gum margin, and it appears worn, shiny and is often discolored at the cervical margin.
What are three things that can cause abrasion?
Three agents of physical weathering that can cause abrasion are moving water, wind and gravity. Also Rocks suspended in the ice of a glacier can cause abrasion of other rock on earths surface. And moving water rocks can become rounded and smooth.
Why is abrasion important?
Abrasion is a principle factor that causes rupture of the materials like rubbers, ceramics, coatings, metals, etc. ... Abrasion test provides the result that helps the user to compare the material or its coating and helps to judge the life of the material.
What are 3 ways rocks can be worn down by abrasion?
Rocks on a beach are worn down by abrasion as passing waves cause them to strike each other.
- Gravity causes abrasion as a rock tumbles down a mountainside or cliff.
- Moving water causes abrasion as particles in the water collide and bump against one another.
- Strong winds carrying pieces of sand can sandblast surfaces.
