Waves are generated by wind blowing over the sea. The characteristics of waves are determined by the strength of the wind, its duration and fetch (distance a wave travels). The stronger the wind the greater the friction on the surface of the sea and therefore the bigger the wave. See more Constructive waves are flat and low in height and have a long wavelength. Their strong swash carries material up the beach, forming a … See more Destructive waves have a large wave height and short wavelength. They have tall breakers that have a high downward force and a strong backwash. Their frequency is high with between 13 and 15 waves per minute. … See more Tides are the rise and fall of sea levels. Tides are caused by the gravitational pull of the moon and to a lesser extent the sun. When the earth, the moon and sun are aligned the gravitational pull is at it’s greatest. This … See more Wave refraction involves waves breaking onto an irregularly shaped coastline, e.g. a headland separated by two bays. Waves drag in the shallow water approaching a headland so the wave becomes high, steep and short. The … See more Webthe distance of sea it has travelled over (the fetch) The stronger the wave, the more erosion it will cause. The four processes involved in erosion are: Hydraulic action
