Waves are undulations on the surface of the water. They are caused by
wind blowing over the surface of the sea. The wave's size depends on
strength of the wind, the duration of the wind and the fetch. As the
wave approaches land the sea gets shallower, the shape of the wave
starts to change. It gets higher and will break on the shore.
Fetch the length of water over which wind has blown before the waves
break on the coast.
Destructive Wave a high wave with a backwash stronger than its
swash, which breaks frequently causing erosion.
Constructive Wave a low wave with a swash which is stronger than its
backwash, which breaks gently encouraging deposition of beach
Swash water which flows up the beach.
Backwash water that drains back down the beach into the sea.
1) Hydraulic Action or Power is the explosion of compressed air
trapped in cracks in cliffs by advancing waves.
2) Corrasion occurs when rock particles are hurled by waves against
3) Corrosion is the chemical decomposition of rocks by sea water.
4) Attrition is the breakdown of rock particles as they hit the cliff
face, and each other.
Wave cut platform a gently slopping area of rock
which is exposed at low tide. It is made from the
boulders which have been eroded form the cliff.
Headlands an area of land that sticks out into the
sea, made of hard rock, Eg. limestone.
Bays an area which the sea has eroded, which
forms an indent in the coast, made of soft rock Eg.
Notches an overhang at the bottom of a cliff which
shows undercutting by waves.
Cliffs are the most common erosional landform found alone the coast.

boulders are dumped and enclosed in wire mesh. They form a
barrier which gradually decreases the waves' energy by dispersing
it. Quite cheap
