- Polish coast of the Baltic Sea. Abrasion is the mechanical scraping of a rock surface by friction between rocks and moving particles during their transport by wind, glacier, waves, gravity, running water or erosion. After friction, the moving particles dislodge loose and weak debris from the side of the rock.

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

Definitions &Translations In dermatology, an abrasion is a wound caused by superficial damage to the skin, no deeper than the epidermis. It is less severe than a laceration, and bleeding, if present, is minimal.Mild abrasions, also known as grazes or scrapes, do not scar or bleed, but deep abrasions may lead to the formation of scar tissue.brasion injuries most commonly occur when exposed skin comes into moving contact with a rough surface, causing a grinding or rubbing away of the upper layers of the epidermis.

What is an abrasion? A RealAge answered. An abrasion (scrape) is a shallow scrape on the skin surface and most commonly found on the hands, elbows, or knees. The wound is shallow and doesn't go far beneath the surface. Because an abrasion exposes millions of nerve endings, it can be very painful. A large abrasion can look and act like a burn.

Difference Between Abrasion and Laceration In this regard, when the skin is wounded it can either become lacerated, or abraded. According to the degree or depth of the injury, abrasion and laceration are only two of the several types of wounds including avulsion, puncture and incision wounds. Abrasion is the milder form of injury compared to laceration because it only involves the scraping away of a certain region of the integument. Thus, it is a more superficial (the most superficial) type of wound. Lacerations, on the contrary, are deeper wounds.

What Is Erosion and How Does It Shape the Earth's Surface? By Andrew Alden. Definition: Erosion is the general name for the processes that break down rocks (weathering) and the processes that carry away the breakdown products (transportation). The physical processes of erosion are called corrasion or mechanical erosion; the chemical processes are called corrosion or chemical erosion. But most examples of erosion include some of both corrasion and corrosion. The agents of erosion are gravity, ice, water (eluvian erosion) and wind (eolian erosion). Erosion is sometimes restricted to transportation, excluding weathering.

Skin Abrasion and Road Rash Treatment The skin is composed of an outer layer (the epidermis) which provides protection, and a deep inner layer (the dermis), which provides the firmness and flexibility of the skin. Abrasions typically refer to an injury that removes these layers of skin. Cyclists often refer to abrasions from crashes as road rash..
