What is meant by abrasion?

Question

What is meant by abrasion?

Answer 1

abrasion is a type of closed wound in which epidermis is scraped leaving behind dermis.it is painful since cuticular nerve endings are exposed.ifdue to injury proper dressing and antibiotics necessary

Answer 2

You mean Abrasion of Skin?

Dermabrasion refer to set of medical procedures where superficial layers of skin are removed using physical techniques. Crude anology would be rubbing your skin with sand paper.

Ok ok this is a question posted in Earth sciences :-/'

Answer 3

Abrasion is mechanical scraping of a rock surface by friction between rocks and moving particles during their transport in wind, glacier, waves, gravity or running water. The intensity of abrasion depends on the hardness, concentration, velocity and mass of moving particles.Abrasion polishes rock faces.

Abrasion by a glacier

A glacier can "carve" a valley, wearing away rocks and soil through abrasion and plucking up and moving large pieces of rock and debris.

Erosion is a broadly defined group of processes involving the movement of soil and rock. This movement is often the result of flowing agents, whether wind, water, or ice, which sometimes behaves like a fluid in the large mass of a glacier. Gravitational pull may also influence erosion. Thus, erosion, as a concept in the earth sciences, overlaps with mass wasting or mass movement, the transfer of earth material down slopes as a result of gravitational force. Even more closely related to erosion is weathering, the breakdown of rocks and minerals at or near the surface of Earth owing to physical, chemical, or biological processes. Some definitions of erosion even include weathering as an erosive process. Though most widely known as a by-product of irresponsible land use by humans and for its negative effect on landforms, erosion is neither unnatural nor without benefit. Far more erosion occurs naturally than as a result of land development, and a combination of weathering and erosion is responsible for producing the soil from which Earth's plants grow.-

Answer 4

abrasion is the physical result of the impact and rubbing together of two solid objects.  Generally a superficial phenomenon (surface scratching).  Usually occurs because one of the objects is harder than the other, and thus one of the objects is more abraded (scratched) than the other.

Answer 5

dont know, what is your think

Answer 6

abrasion is the process of abrading the contact area of any material with abrassive. for a material is to be abrassive, it should have hardness index more than that of abraded material and should pocess a rough surface....

abrasion is actually the process of removal of particles of a material having lower hardness index relative to the material in contact, which moves relatively.

Answer 7

In most simple meaning it means scrapping of a surface of a solid by movement of a  grain in contact.

Answer 8

Abrasion is mechanical scraping of a rock surface by friction between rocks and moving particles during their transport in wind, glacier, waves, gravity or running water, after friction, the moving particles dislodge loose and weak debris from the side of the rock, these particles can be dissolved in the water source.

The intensity of abrasion depends on the hardness, concentration, velocity and mass of moving particles.

Abrasion by a glacier

A glacier can "carve" a valley, cirque, or a tarn (glacial lake), by wearing away rocks and soil through abrasion and plucking up and moving large pieces of rock and debris.

A virtually smooth marine platform cut by the ocean waves at a coastline. If it is currently being fashioned it will be exposed only at low tide, but there is a possibility that the wave-cut platform will be hidden sporadically by a mantle of beach shingle, which is the abrading agent. If the platform is permanently exposed above high-water mark it is probably a raised-beach platform.

Answer 9

Abrasion may refer to:

Abrasion (medical), a wound consisting of superficial damage to the skin



Abrasion (dental), the loss of tooth structure by mechanical forces from a foreign element



Abrasion (geology), mechanical scraping of a rock surface by friction between rocks and moving particles



Abrasion (band), an Australia heavy metal band



Abrasion (BDSM), a human sexual practice involving sexual arousal from contact with abrasive substances

Answer 10

a scraped spot or area; the result of rubbing or abrading: abrasions on his leg caused by falling on the gravel.  

-- the act or process of abrading.
