Erosion and changes in the form of river banks may be measured by inserting metal rods into the bank and marking the position of the bank surface along the rods at different times. [23] Thermal erosion is the result of melting and weakening permafrost due to moving water. [24] It can occur both along rivers and at the coast.
Gastric erosion occurs when the mucous membrane lining the stomach becomes inflamed. Specifically, the term "erosion" in this context means damage that is limited to the mucosa, which consists of three distinct layers: the epithelium (in the case of a healthy stomach, this is non-ciliated simple columnar epithelium), the basement membrane, and the lamina propria.
Bone erosion is the loss of bone from disease processes. Erosive arthritis is joint inflammation ( arthritis ) with bone destruction, and such conditions include rheumatoid arthritis . [ 2 ] Bone erosion is the loss of bone in a certain area, rather than a change in bone density , which is found in osteoporosis .
Although the terms erosion and denudation are used interchangeably, erosion is the transport of soil and rocks from one location to another, [1] and denudation is the sum of processes, including erosion, that result in the lowering of Earth's surface. [2]
Erosion: An erosion is a discontinuity of the skin exhibiting incomplete loss of the epidermis, [32] a lesion that is moist, circumscribed, and usually depressed. [ 21 ] [ 33 ] Excoriation : A punctate or linear abrasion produced by mechanical means (often scratching), usually involving only the epidermis, but commonly reaching the papillary ...
Ablation near the electrode in a flashtube.The high-energy electrical arc slowly erodes the glass, leaving a frosted appearance. Ablation (Latin: ablatio – removal) is the removal or destruction of something from an object by vaporization, chipping, erosive processes, or by other means.
Bank erosion is the wearing away of the banks of a stream or river. This is distinguished from changes on the bed of the watercourse, which is referred to as scour. Erosion and changes in the form of river banks may be measured by inserting metal rods into the bank and marking the position of the bank surface along the rods at different times. [18]
Acid erosion is a type of tooth wear. It is defined as the irreversible loss of tooth structure due to chemical dissolution by acids not of bacterial origin. [ 1 ] Dental erosion is the most common chronic condition of children ages 5–17, [ 2 ] although it is only relatively recently that it has been recognised as a dental health problem. [ 3 ]
