coastal recap
types of erosion
attrition -pebbles bash together to become smooth
solution -limestone and chalk suffer
hydraulic power is air is forced into tiny holes in cliffs makes holes bigger than turns into cracks
corrosion or abrasion (sandpaper action) rubs against surface
chashes :
swash
breaks onto the swore
goes in at the south west where as backwash goes back staright 90 degree angle because of gravity
constructive+destructive waves
conservative builds up the beach
destructive is taller waves that crash and it returns sediment to sea
biological weathering
the weakening of the breakdown of rocks and plants
erosion carrys it
concdanto
horizontal rock te sea goes straight up so the other way
the rock slowly erodes until we are left with a hole
physical weathering
the breakdown of rocks through the heat or coldness
chemical weathering
the chemicals in the salt will weaken the rock over time
mass movement
where a slope gets heavy and wet due to the heavy rain and falls down
deposition
happens when the swash is stronger then the backwash and associated with constructive waves
