The wind can cause small particles to be lifted and therefore moved to another region (deflation). Suspended particles within the wind may impact on solid objects causing erosion by abrasion (ecological succession). Wind erosion generally occurs in areas with little or no vegetation, often in areas where there is insufficient rainfall to support vegetation.<ref>{{cite web|author=United States Geological Survey|author-link=United States Geological Survey|year=2004|title=Dunes&nbsp;– Getting Started|url=http://geomaps.wr.usgs.gov/parks/coast/dunes/index.html|url-status=dead|archive-url=https://web.archive.org/web/20120427204448/http://geomaps.wr.usgs.gov/parks/coast/dunes/index.html|archive-date=2012-04-27|access-date=2009-03-21}}</ref>
