erosion

 [e-ro´zhun]
an eating or gnawing away; a shallow or superficial ulceration; in dentistry, the wasting away or loss of substance of a tooth by a chemical process that does not involve known bacterial action. adj., adj ero´sive.
cervical erosion destruction of the squamous epithelium of the vaginal portion of the cervix, due to irritation and later ulceration.

e·ro·sion

(ē-rō'zhŭn),
1. A wearing away or a state of being worn away, as by friction or pressure. Compare: corrosion.
2. A shallow ulcer; in the stomach and intestine, an ulcer limited to the mucosa, with no penetration of the muscularis mucosa.
3. Chemically induced tooth loss, occurring mainly through acid dissolution. When the cause is unknown, it is referred to as idiopathic erosion. Synonym(s): odontolysis
[L. erosio, fr. erodo, to gnaw away]

The superficial destruction of a surface by friction, pressure, ulceration, or trauma.

erosive (ĭ-rō′sĭv) adj.

erosion

[irō′zhən]
Etymology: L, erodere, to consume
1 the wearing away or gradual destruction of a surface. For example, a mucosal or epidermal surface may erode as a result of inflammation, injury, or other causes, usually marked by the appearance of an ulcer. See also necrosis.
2 the action of acid (low pH) substances dissolving tooth structure. Can be due to habitual sucking on citrus fruits such as lemons, from acidic swimming pool water, or gastroesophageal reflux.

erosion

A wearing away, ulceration. See Apple core erosion, Cervical erosion.

erosion

the wearing away of geological formations such as rock, soil, etc. For example, deafforestation or the removal of hedges causes soil erosion.

erosion (ērō´zhən),

n the chemical or mechanicochemical destruction of tooth substance, the mechanism of which is incompletely known, which leads to the creation of concavities of many shapes at the cementoenamel junction of teeth. The surface of the cavity, unlike dental caries, is hard and smooth.

El planteamiento central de este estudio es analizar la evolucion y el grado de los procesos de erosion existentes, a partir de un enfoque de tres niveles, que comprende el uso de fotografias aereas, ortofotos, imagenes satelitales y recorridos por el area en observacion (Larsson y Stromquist, 1995), metodologia que fue parcialmente sugerida en 1972, por la Corporacion de Los Andes (Corpoandes), (refiriendose a un estudio multi-temporal con base en fotografias aereas) como potencialmente interesante para analizar las variaciones de la erosion (Ferrer, 1977) y que lamentablemente no se realizo dado las limitaciones tecnologicas de la epoca en la que fue propuesta o la falta de continuidad de investigaciones alusivas a la micro-cuenca.
