They are also the first to dissipate storm-generated wave and current energy. Although foredunes may be large and continuous, they typically are separate rounded knolls. |

|
What is a Healand?
|
A narrow piece of land that project from a coastline into the sea.
|
What is Long shore drift?
|
Longshore drift transport of sediment, mainly sand.
|
Refraction?
|
When the waves front bends to fit the coastline.
|
What is a Rip?
|
A rip are localised, fast-flowing currents that run out towards the seabed. Rip currents depend on the height and duration of the waves & on the contours & shapes of the seabed
|
What is Sand Dunes?
|
A ridge of sand created by the wind; found in deserts or near lakes and oceans
|
What is a Spit?
|
Spits are formed when the coastline suddenly changes direction. The long shore drift continue in the same direction but puts its material down to form a spit that looks like a long hook sticking out to sea. |
