Terminology

Constructive Waves- Long, low waves that spill onto the beaches and construct beaches. Normally, they have strong swash however, limited backwash.

Destructive Waves- Short, steep waves that plunge onto the beach with force and are capable of eroding cliffs. Normally, they have strong swash but even stronger backwash.

Swash- Is the movement of waves up a beach.

Backwash- Is the movement of waves down a beach.

Marine Erosion- Is the erosion of rocks by the action of the sea.

Hydraulic action- Is the sheer movement of waves breaking against the cliffs causing fragments of the cliff to break off.

Abrasion- Is when waves pick up sand and pebbles and as waves break these are hurled against the cliff face.
