1. Option 2B: Coastal Landscapes and Change
Aim:
To know the outline of this topic and to complete the introduction tasks

2. Sub topics across this option
Enquiry Q1:Coastal processes
Enquiry Q2:Landforms and landscapes
Enquiry Q3:Coastal risks
Enquiry Q4:Managing risks and conflicts

3. Specification content

4. Coastlines https://www.youtube.com/watch?v=EPyl1LgNtoQ
Different countries and coastlines from space
Different coastlines from around the world

5. Enquiry question 1: Why are coastal landscapes different and what processes cause these differences
In pairs write down words that you associate with the coast or different types of coastlines that you understand.
Here are some key words you may have added
Littoral zone – Divided into sub zones – Beach, offshore, backshore, nearshore, cliffs
Waves – high tide, low tide
Wave energy
Human activity
Transfer of sediments
Geology
Sand dunes
Mud flats
Erosion
Deposition
Vegetation
Rocky coastline
Coastal Plains
Salt marshes

6. Extreme events & Human Development
Coasts experience natural extreme events. Give named examples of such events -
Storm surges
Tsunamis
Tropical Cyclones
Name examples of Human development along the coast-
Ports
Varied types of industry
Power plants
Residential
Varying types of tourism

9. The Littoral Zone (and its subzones)
Match up the images with the different littoral zones in the block diagram.

10. 3 Backshore
5 Cliffs/Coast
4 Offshore
2 Nearshore
1 Beach/foreshore

11. The Littoral zone
Complete the card sort and add your answers in the table page 11 of your booklet
Make sure you have a description of each zone and the factors which are responsible for changing each zone.

12. Two types of coastline
Rocky—(or cliffed) coastlines have cliffs or varying heights from few to hundreds of metres. Cliffs are formed from rock but the hardness of it is variable.
Coastal Plains– the land gradually slopes towards the sea across an area of deposited sediments, with sand dunes and mud flats being the most common examples. These coasts are sometimes referred to as alluvial coasts.

13. INPUTS PROCESSES OUTPUTS Because the coast is constantly
changing it helps to think of it
as a system driven by Wave
Energy. Each component of
The coastal system has
INPUTS
PROCESSES
OUTPUTS
Weathering
Mass Movement

14. Classification of Coastal environments
Make notes from table 8.1 p111
Remember that INPUTS such as
TIDES
WAVES
RIVERS
All influence the changes along
the coast.

Deposition = North Wales - of-erosion-and-coasts-of-deposition.html

16. Sediment supply
Where does the sediment that is found around our coastlines come from?
Look at a case study e.g – Holderness
1 – Flamborough Head
2. Spurn Point
3. Along the coast
Wave direction 1
North Sea 3
Transportation
Sediment comes from the weathering
& erosion of the northern area at 1. Here
are landforms of EROSION
Its then transported along the coast as
Longshore Drift in a zig zag motion as the
Waves approach the shore. This sediment
Which is held in suspension is deposited
at Spurn Point location 2. This is a SPIT, a
landform of DEPOSITION.
Chalk – Very hard rock
Boulder Clay – Very soft rock
Clay – very soft rock 2

19. Research – Contrasting Coastlines
Look up online the three Contrasting Coastlines. Make sure you get a named example for each one and an image! Describe each one and explain its formation. Print off and glue each one into the blank pages that follow in your booklet.
· Cliffed Coastlines
· Sandy Coastlines
· Estuarine coastlines
