Q

east anglia

A

low lying
sands and clays (deposited by glaciers)
produce fertile soil for farming
hedges used for field boundaries

Q

concordant

A

strata=parallel to coast
hard rock= small crack
soft rock= eroded lots
hard rock= stops eroding

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:

22
Q

constructive waves

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

winter waves

24
Q

destructive

A
  • plunging waves
  • taller and closer together
  • strong backwash
  • create steep beach profile
25
coastal erosion is
the wearing away and breaking down of rocks
26
coast erosion caused by
hydraulic action abrasion attrition
27
hydraulic action
water forced into cracks, air blast out, force rock apart
28
abrasion
loose sediment thrown against cliffs and wears away rock off the cliff
29
attrition
loses sediment knocked off the slide and collides with other sediment and gets worn down
30
sediment is transported by
longshire drift
31
longshore drift
waves break at an angle rather than parallel
32
spit
sand from longshore drift is deposited forming a long sandy neck - recurved end - salt marches formed
33
plants that grown on sand:
``` -long roots (hold in place from wind) -tough waxy leaves (stop getting sandblasted) -survive being sprayed by saltwater ```
