1

a) What is the littoral zone?

a coastal zone

2

a) What is the back-shore?

the area usually above the influence of the waves which changes. This contains the storm beaches as well as pebbles and berms, shingles and ridges

3

a) What is the foreshore?

the inter-tidal or surf zone which contains sand runnels or ridges which has the most energy (dynamic)

4

a) What is the nearshore?

the breaker zone which contains long shore bars and break point bar.

5

a) What is the offshore?

Beyond influences of the waves which has the least action.

6

a) What zone is most influenced by humans?

backshore

7

What are inputs on the beach? a

Marine - waves/storms
Atmospheric - weather/climate
Terrestrial - geology
People - activity, management

8

What are processes on the beach? a

Weathering
Mass movement
Erosion
Transportation

9

What are outputs on the beach? a

Erosion land forms
Deposition land forms
Different coast types

10

How are coasts classified? a

geology, energy level. formation processes, sea level changes, erosion and deposition balance, formation processes

11

What is an example of a sandy beach? a

Belgium coastline
- vegetation stabilises coast

12

What is an example of a estuarine coastline? a

Lymington on the south coast of England
- mud flats
- gradual slope to sea

13

What is the difference of a primary/secondary coast? a

primary = land processes
secondary = marine dominated

14

What is the difference between a emergent and submergent coastline? a

Emergent = coast rising by sea level change
Submergent = flooded coasts by sea by sinking land

15

What is the difference between a low and higher energy coastline? a

low = sheltered, limited fetch, low wind
high = exposed, prevailing winds, fetch, strong winds

16

What does the teeside-ex line show in the UK? a

That the north has glaciated due to harder rocks eg granite and basalt (igneous), rocky (cornwall), southern area has softer flatter rocks (malleable)

17

How do you classify a coast? b

using the circle (advancing coasts/retreating coast) (emergence/submergence) (deposition/erosion)

18

What features are on a rocky cliff face? c

destructive waves
erosion processes
rock falls
clay slumping
tourism

19

What features are on a coastal plain or estuarine? c

muddy
The WASH
lowland flat areas
low energy
build up of sediment
flood plains
trade links

20

What features are on a sandy beach?

no LSD
swash aligned
deposition land occurs
low wave energy
Tourism and leisure
