COAST GENERAL
The differences in height or steepness of a slope
What is relief?
Two types of waves
What is constructive and destructive?
Sheer force of the water as it hits against a cliff
What is hydraulic action?
A piece of land projecting into the sea formed where there are alternating bands of hard and soft rocks
What is headland?
The purpose of coastal management strategies
What is to reduce the effects of erosion and flooding?
The stretch of land bordering the sea
What is coast?
The removal of sediments and rocks by waves
What is erosion?
Sediments move in a zig zag pattern along the coast involves swash and backwash
What is longshore drift??
Which of the following is not a landform of coastal erosion? headland, beach, cave
What is a beach?
The use of man-made structures to reduce the erosive power of waves
What is hard engineering?
Distance of open water over which waves travel
What is fetch?
Three functions of waves
What is erosion, transportation and deposition?
Large rocks and boulders roll along the sea bed.
What is traction?
Name three landforms of coastal erosion
What is headland, cave, arch, stack, stump?
This strategy works with the natural environment to protect coastal areas
What is soft engineering?
The formation is waves is caused by
What is wind blowing over the surface of the water?
The movement of the material eroded by waves
What is transportation?
Attrition is the process by which
What is rocks and boulders transported by waves collide and break up into smaller pieces and become more rounded?
Bars are spits are a result of which function of waves
What is deposition?
Concrete or wooden barriers built at right angles to the beach to prevent longshore drift, trap sediments
What is groynes?
The size and energy of waves depend on these three factors
What is fetch, strength of the wind and how long the wind is blowing for?
Deposition occurs when
What is when the sea loses energy and drops eroded material?
Four main processes of wave transport
What is traction, saltation, suspension, solution?
Place the following in the correct order of formation
caves, stump, arch, headland, stack
What is headland, cave, arch, stack,stump
Four hard engineering strategies
What is sea wall, rock armour, groynes and gabions?
