coasts lessons 3-4 Flashcards
the height and slope of the land
relief
vertical or near vertical profile with notches reflecting strata that are more easily eroded
horizontal dip
sloping profile with one rock layer facing the sea; vulnerable to rock slides down the dip slope
seaward dip, low angle
profile may exceed 90 degrees producing areas of overhanging rock; very vulnerable to rock falls
seaward dip, high angle
steep profiles of 70-80 degrees producing a very stable cliff with reduced rock falls
landward dip
how can micro features form?
faults joints and fissures can be exploited by erosion to create micro features such as caves and wave cut notches
the pressure water experiences at a particular point below the water table due to the weight of water above it
pore water pressure
