Erosional landforms Nature of eroded coastlines determined by two factors: direction, strength and frequency of waves and geology of coastline Cliffs: produced by coastal erosion. wave action undermines land leading to slumping/rock falls. produces a steep ‘edge’...
corals = tiny marine animals (polyps). reefs formed from millions of them living together in colonies. skeletons are calcium carbonate cups and they join to form a stony, hard mass of limestone. next one grows on top of the generation that just died, reef grows up...
Coastal features found on tidal mud flats in tropical and sub-tropical areas. Features: stilt roots — anchor plant in soft mud, slows wave movement and encourages more mud deposition; extending coastal area into sea and reducing erosion risk. conical breathing...
coastal management has 3 aims: protect coastline from erosion. protect coast from seawater flooding. conserving fragile ecosystems sustainable coastal management has to consider the 3 main aspects of sustainable development: environmental, economic and social...
Waves Size depends on: wind speed, length of time wind blows in constant direction and length of fetch California: very big waves as come from Aleutian Islands, 4000m fetch so time for wave energy to build up. Mediterranean: very small waves as surrounded by...
