Most bays have streams flowing into them, and since this water has to get out, it is rare that a baymouth bar will completely close the entrance to a bay. Depositional features at the coast may be temporary (beach cusps) or longer-lasting (spits), but others are transformational; they undergo change from one form to another over relative short periods of time measured in decades.Environmental habitats at the coast alter as a result of plant succession, which . The main factor in determining if a coast is dominated by erosion or deposition is its history of tectonic activity. Sea level rise may also contribute to accretion, as material is pushed up with rising sea levels. Text on this page is printable and can be used according to our Terms of Service. Longshore drift moves material along the coastline.
