16
Q

joints in rock

A

small vertical cracks in rocks

17
Q

faults in rock

A

larger cracks

caused by past tectonic moment where rocks have moved

18
Q

joints in a cliff

A
  • widen to form a cave
  • erode into an arch
  • collapses to form a stack
  • eroded down into a stump
19
Q

causes of waves

A

wind + friction

- when wind blows across the sea, friction between wind and water causes waves

20
Q

size of waves depends on

A
  • wind strength
  • how long wind blows for
  • fetch (length of water wind blows over)
21
Q

summer waves:

A

constructive

22
Q

constructive waves

A
  • small waves
  • strong wash
  • gentle slope
23
Q

winter waves

A

destructive

24
Q

destructive

A
  • plunging waves
  • taller and closer together
  • strong backwash
  • create steep beach profile
25
Q

coastal erosion is

A

the wearing away and breaking down of rocks

26
Q

coast erosion caused by

A

hydraulic action
abrasion
attrition

27
Q

hydraulic action

A

water forced into cracks, air blast out, force rock apart

28
Q

abrasion

A

loose sediment thrown against cliffs and wears away rock off the cliff

29
Q

attrition

A

loses sediment knocked off the slide and collides with other sediment and gets worn down

30
Q

sediment is transported by

A

longshire drift

31
Q

longshore drift

A

waves break at an angle rather than parallel

32
Q

spit

A

sand from longshore drift is deposited forming a long sandy neck

  • recurved end
  • salt marches formed
33
Q

plants that grown on sand:

A
-long roots 
(hold in place from wind)
-tough waxy leaves 
(stop getting sandblasted)
-survive being sprayed by saltwater
