coastal landforms
coastal management
waves wear away the coast using four processes of erosion
hydraulic action
corrasion
attrition
corrosion
destructive waves erode the coast
wind and destructive waves
fetch and destructive waves
cliffs retreat as a result of erosion, weathering and mass movements
coastal weathering
headlands and bays form where erosion resistance is different
headlands are eroded to form caves, arches, stacks and stumps
cove
coast
constructive waves
longshore drift LSD: the movement of material along the coast by the action of waves
four processes of transportation
deposition
beaches
sand beaches
shingle beaches
spits:
form at sharp bends in the coast - at river mouth
LSD transports material past the bend and deposits it in the sea
wind/waves curve end of spit
bar:
formed when a spit joins two headlands together
cuts off bay from sea
lagoon forms behind

social reasons to protect the coast
environmental reasons to protect the coast
