|
small low-energy waves that deposit sand onto beaches |
constructive waves |
|
|
occurs when waves crash over rock shelves and move rock and other material helping to erode the rock itself |
corrasion |
|
|
the action of salt minerals like iron that are contained in rock, weakening the rock and making it more susceptible to erosion |
corrosion |
|
|
the depositing of sand and rock particles cause by wind and wave action forming features such as beaches |
deposition |
|
|
large waves formed by tropical cyclones and storms that erode material from beaches |
destructive waves |
|
|
the removal of rock and sand particles as a result of wind and wave action |
erosion |
|
|
the distance wind travels over the ocean to form waves |
fetch |
|
|
the closest dune to the ocean or the first due in the sand system |
foredune |
|
|
where waves enter cracks in rocks, air is compressed by the force of the water causing erosion and forming features such as blow-holes |
hydraulic action |
|
|
the process, caused by waves hitting the coast at an angle, that is responsible for moving sand along the coast |
longshore drift |
|
|
the bending of waves around headlands and into bays |
refraction |
|
|
the active part of the coast in terms of erosion and deposition of sand and wave action; the surf zone is immediately adjacent to the coast and the swash zone is at the shore once the waves have broken |
surf and swash zone |
|
|
the natural progression of vegetation from low-lying, salt tolerant plants on the foredune, through to shrubs and established trees on the hind dunes |
vegetation succession |
|
|
the vertical distance between the trough and the peak of a wave |
wave height |
|
|
the horizontal difference between wave peaks |
wavelength |
