Erosion is the geological process in which earthen materials are worn away and transported by natural forces such as wind or water. A similar process, weathering, breaks down or dissolves rock, but does not involve movement. Most erosion is performed by liquid water, wind, or ice (usually in the form of a glacier).

: the sequence of changes in a landscape from the start of its erosion by running water, waves and currents, or glaciers until it has been reduced to the baselevel of erosion which limits the activity of the agents concerned. — called also geomorphic cycle.

The three main forces that cause erosion are water, wind, and ice. Water is the main cause of erosion on Earth.

An abrasion is a type of open wound that’s caused by the skin rubbing against a rough surface. It may be called a scrape or a graze. When an abrasion is caused by the skin sliding across hard ground, it may be called road rash. Abrasions are very common injuries. They can range from mild to severe.

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.

Noun. ▲ An area damaged by scraping or wearing away. graze. scrape.

The scraped skin of an abrasion can contain particles of dirt. First aid treatment includes: Clean the wound with a non-fibre shedding material or sterile gauze, and use an antiseptic such as Betadine. If there is embedded dirt, Savlon may be used as it contains an antiseptic and a surfactant to help remove debris.

Most scrapes heal well and may not need a bandage. They usually heal within 3 to 7 days. A large, deep scrape may take 1 to 2 weeks or longer to heal.

Abrasions, a milder form of injury compared to lacerations, involve the scraping away of a layer of the skin, usually caused by friction with a rough surface. Lacerations (wounds) are more severe, and deeper tears of the skin.

The cells in the superficial or upper layers of skin, known as the epidermis, are constantly replacing themselves. This process of renewal is basically exfoliation (shedding) of the epidermis. But the deeper layers of skin, called the dermis, do not go through this cellular turnover and so do not replace themselves.

The epidermis repairs itself, but the skin does not completely recover its natural appearance, leaving a scar. This scar will improve, and change. This is why it is important not to judge its appearance at the time of the injury, but rather to wait several months after it has formed.

The goal is to do things the help the skin regenerate and protect it from further harm.

Your skin’s protective moisture barrier is damaged, and simply layering on a rich moisturizer isn’t going to fix it. Chances are, you are doing something day in and day out that is causing your skin to get damaged, and the moment you take out the culprit, your skin’s barrier can naturally repair itself.

It can take anywhere between 2 weeks to an entire month or more to repair your skin’s natural barrier function. You’ll be able to tell when your skin is healed; inflammation will be decreased, there’ll be a reduction in skin sensitivity, oiliness, dryness, dehydration, and reactivity.
