Cards in this deck (13)
- 1Coasts The Littoral ZoneBy Daniel Armstrong
- 2How does hydraulic action affect cliffs and wallsWater pushes air into cracks in the rock and traps it. The force of the water and trapped air causes cliff to collapse
- 3How do headlands and bays formLayers of hard and weaker rock. Water erodes weaker rock causing it to retreat creating a headland of hard rock and bay of soft rock.
- 4What do headlands cause waves to dowave refraction
- 5What is hydraulic actionWave pounding
- 6What is attritionRocks hit each other breaking up
- 7what is Corrosion (solution)Dissolved rock
- 8What is abrasion (corrasion)Rubbing of rocks (sand-paper effect)
- 9What landforms form as a result of erosionWave cut platform
Stump
Stack
natural arc - 10Characteristics of a destructive waveHigh in proportion to length
Tall breaker breaks with great down force
Weak swash
strong backwash
High frequency - 11Characteristics of a constructive wavesLong in proportion to length
Strong swash
Weak backwash - 12What affects the fetchDistance the waves travel. Some travel across entire atlantic ocean
- 13How is sediment transported across the beachThrough the process longshore drift
Swash pushes rock at an angle up the beach
backwash is always at a right angle to beach so dragged straight down
(prevailing wind direction)
