COASTS - Coggle Diagram
COASTS
HEADLAND EROSION
corrosion and hydralic action
destuctive waves
abbrasion
caves arches and stumps
wave refraction
DISPOSITIONAL LANDFORMS
spits
chage direction at esturesy
bars
spit crosses bay
lagoon behind
beach
constructive wave
tombolos
spit across to a island
cuspate foreland
long shore drist = 2 diections
2 spits meet
new land formed
SEDIMENT CELL
source
subarel processes eriosn bring sediment
transfer
longshore drift , wind, tides
sinks
deposited landforms
uk = 11 sediment sell with own SMP
closed system
MASS MOVEMENT
gravity forces unsuppoted material
rapid retrete in saturated areas commonly
slides
down slope in staight line
rock fall
erosion and weather fragments fall leaveling laus screen slope
slumps
rotation
EROSION PROCESSES
attrition
hit each othe and break
abbrasion
sediment hit clift
hydraulic action
water in cracks = force
corrosion
chemical reaction - sea water and eg lime stone
LONG SHORE DRIFT
prevailing wind
gravity = backwash
right angle
sediment carries along beach
CLASSIFICATION
liroral zone
inputs
outputs
high energy
destuctive
low energy
constructive
COASTLINE
concordant
parellel rocks
discordant
90 degree angle
WEATHERING
chemical
chemical compostiton changed = rock breaks down
mechanical
sakt water
biological
roots and algea
morphology
concordant = dalmation
offshore islands
coastal inlets
dicordant = headland and bays
wave refaraction = caves arches
GEOLOGICAL STRUCTURE
dip
angle formedwith horizontal bedding planes
steep = dip to land
joints and faults
stress and tectonic processes
weaknesses erosion
WAVES
constructive
swash depostion
destructive
erosion back wash
WAVE CUT PLATFORM
destuctive wave
abbasion at clift face crve at bottom
collapses above = wave cut knotch
lot of collapsing = wave cut platform
LITHOLOGY
physical property of rock
sedimenrty= most erosion
metamorphic= most resistant
igneous
VEGITATION
sandunes
xerophytes = dry
halophytes = sea water
