Presentation Transcript
A pass around On w/boards Pass round 1. Draw a diagram to show the features listed 2. Label it 3. Add an annotation 4. Check the definition is correct Wave length Wave height Wave crest Wave trough Wave steepness At what point will a wave break?
You have 20 minutes Level 1 - Draw two diagrams to show constructive and destructive waves, annotate the characteristics Level 2 distinguish between destructive and constructive waves Level 3 consider how wave type affects beach morphology - How, over time can constructive waves alter the beach profile which then encourages waves that are more destructive? What affect do destructive waves have on the beach profile? How does this affect the waves approaching the beach?
Write a sentence or two that uses all four key terms Wave period, Wave energy, Swash, backwash Tidal range, Tidal bore, Neap tide, Spring tide Sediment cell, sediment source, UK, estuary's
Which is the odd one out Fjord, raised beach, ria Sea level rise, Eustatic rise, Isostatic rise Sea level fall, Isostatic rise, Eustatic rise Submergence, sea level rise, Eustatic fall Sea level fall, Isostatic fall, emergence
Decide which causes a greater amount of weathering Freeze thaw Biological weathering Chemical weathering Acid rain Pressure release
Decide which of the following is best, justify your answer Hard engineering Sea wall or Rip rap Revetments or Gabions Groynes or barrages Final decision: Which is best hard engineering or soft engineering? Soft engineering Marsh creation or Beach nourishment or Dune regeneration
