The action of wavesWaves are created by wind blowing over the surface of the seaFriction is created - producing a swell in the waterThe water particles then rotate and the wave moves forward
Wave Frequency Velocity FetchWind
Types of wavesWhen a wave breaks, water is washed up the beach - called swashThen the water runs back down the beach - called backwash
http://www.youtube.com/watch?v=tN42EWWTP3w Note: Backwash is always at right angles to the beachWhenever you see either one on the video, shout SWASH or BACKWASH!
Waves can be constructive or destructiveWith a constructive wave, the swash is stronger than the backwash
With a destructive wave, the backwash is stronger than the swash.
Destructive WavesConstructive Wavesbackwash>swashswash>backwash
Constructive Waves Created in calm weather
Break on the shore and deposit material, building up beaches
Destructive Waves Created in storm conditions when the wind is powerful and has been blowing for a long time
Occur when wave energy is high and the wave has travelled over a long fetch, tend to erode the coast
Constructive or Destructive?
Check your answers
Demonstrate: Decide whether the statements are talking about destructive or constructive waves and add them to the correct diagramThe swash is stronger than the backwashThe backwash is stronger than the swashShort wave heightTall wave heightStrong swash causes a lot of material to be deposited on the beachStrong backwash pulls sand and shingle back to the sea eroding the beach
