layers of sedementary rock layered horizontally to the sea, breaks in these rocks create secretive coves.
1 of 23
discordant coastline
layers of sedemtary rock layered vertically to the sea, bays and headlands are formed by diferent erroding times in the diferent types of sedemenetary rock.
2 of 23
arch
when a cave errodes the whole way through.
3 of 23
stack
when an arch colapses and becomes issolated
4 of 23
stump
when a stack falls over with only the tip showing above water level
5 of 23
fetch
the distance a wave travels
6 of 23
swash
the power of a wave coming up the beach
7 of 23
backwash
the power of a wave going away from a beach directed by gravity
8 of 23
biological weathering
roots or burrowing animals can break up rocks and move them
9 of 23
chemical weathering
acidic rain breaks down, and disoves the rocks
10 of 23
physical weathering
freezed water expands in the cracks over night and then melts during the day
11 of 23
rock fall
one or two rocks fall down a cliff
12 of 23
slumping
a large sheet/ledge of rock falls down
13 of 23
sliding
litle patches of rock fall down, bit by bit
14 of 23
hydraulic action
water is driven into the cracks widening and erroding them
15 of 23
attrition
rocks bang against each other causing errosion
16 of 23
abrasion
rocks and sand rub againist each other like sand paper erroding at the material
17 of 23
corosion
acidic rain or chemicals break down the rock
18 of 23
neap tides
they happen twice a month in the first and third quaters of the moon. they are not as high as spring tides
19 of 23
spring tides
they happen around the newmoon and are the higest type of tide
20 of 23
sedement cells
a closed system arpound a coastline were sedement is deposited
21 of 23
constructive waves
they have a stronger swash than backwash and deposite sand
22 of 23
destructive waves
they have a stronger backwash then swash and take material
