What is Beach erosion?
[[Image:Erodedcliffpacifica.jpg|thumb|Beach erosion at Cabrillo National Monument, California.]] '''Coastal erosion''' is a term for the removal of [[beach]]es or [[dune]]s by [[wave]]s, [[Tide|tidal currents]], wave currents, or [[drainage]]. Waves, caused by storms and [[wind]] cause coastal [[erosion]]. On rocky [[coasts]], coastal erosion results in dramatic rock formations in areas where the coastline contains rock layers. Softer areas become [[eroded]] much faster than harder ones, which can cause things like [[Tunnel|tunnels]], [[Bridge|bridges]], [[Column|columns]], and [[Pillar|pillars]]. ==Other websites== *[http://www.whoi.edu/page.do?pid=11914 Coastal Erosion Information from the Coastal Ocean Institute] {{Webarchive|url=https://web.archive.org/web/20090505191353/http://www.whoi.edu/page.do?pid=11914 |date=2009-05-05 }} *[http://www.environment-agency.gov.uk/homeandleisure/107495.aspx Environment Agency guide to coastal erosion] {{geo-stub}} [[Category:Geology]] [[Category:Beaches|Erosion]] [[Category:Erosion]]
