Coastal

Front 1

Small low energy waves that deposit sand onto beaches.

Back 1

Constructive Waves

Front 2

The action of salt on minerals like iron that are contained in rock, weakening rock and making it more susceptible to erosion.

Back 2

Corrosion

Front 3

Large waves formed by tropical cyclones and storms that erode material from beaches.

Back 3

Destructive Waves

Front 4

CorrasionOccurs when waves crash over rock shelves and move rock and other material helping to erode the rock shelf away.

Corrasion

Front 5

DepositionThe depositing of sand and rock particles caused by wind and wave action forming features such as beaches.

Back 5

Deposition

Front 6

The removal of rock and sand particles as a result of wind and wave action.

Back 6

Erosion

Front 7

The distance the wind travels over the ocean to form waves.

Back 7

Fetch

Front 8

The closest dune to the ocean or the first dune in a sand dune system.

Back 8

Foredune

Front 9

Where waves enter cracks in rocks, air is compressed by the force of the water causing erosion and causing features such as blow holes.

Back 9

Hydraulic Action

Front 10

The movement of material along a coast by waves which approach at an angle to the shore but recede directly away from it.

Back 10

Longshore Drift

Front 11

Change in direction of propagation of any wave as a result of its travelling at different speeds at different points along the wave front.

Refraction

Front 12

The swash zone, defined as that part of the beach extending from a nearshore shallow depth to the limit of maximum inundation, is a relatively narrow region of great importance for the exchange of sediment between land and sea.

Surf and Swash Zone

Front 13

The evolution of plant communities at a site over time- from pioneer species to climax vegetation. At each stage of the succession the plant community alters the soil and microclimate, allowing the establishment of another group of species.

Vegetation Succession

Front 14

In fluid dynamics, the wave height of a surface wave is the difference between the elevations of a crest and a neighbouring trough. Wave height is a term used by mariners, as well as in coastal, ocean and naval engineering.

Front 15

The distance between crests (or troughs) of a wave.
