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]

erosion

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

To date, most investigations of soil erosion (Alam and Jamil, 2009; Bai et al., 2008; Gitas et al., 2009; IAEA, 2004) at the huge scale have emulated two general methodologies: (l) Assessment by the regional soil loss variables or accessible models (Bashir et al., 2013) and (2) Estimating soil loss inferring from graph and micro catchment gauges to catchments, watersheds and provincial gauges (Zhang et al., 2009; Braimoh and Vlek, 2008; Farhan et al., 2013).
