9. •Erosion – mechanical wearing away of rocks
•Corrasion – rocks hurled at the base of a cliff between high and low
tide
•Attrition – rocks smashing and rubbing against each other become
smaller over time
•Solution – rocks dissolve by the sea
•Hydraulic action – water forced into cracks, the pressure causes them
to widen
•Long shore drift – the zigzag movement of material along a coastline
(Swash and Backwash)
•Deposition - the dropping of rock
10. Prevailing wind.
Waves travel towards the
beach at an angle driven
by the prevailing wind-
moving material towards
the beach- SWASH.
Waves runs back down at
right angles to the beach-
following the steepest
gradient under gravity-
called BACKWASH.
Material will travel with it.
In this way material is
transported along the
coastline- called Long
Shore Drift (L.S.D).
11.
12. Draw a diagram that illustrates the
formation of a how a cliff retreat and
the formation of a wave cut platform.
13. 1.Between high and low tide rocks
are hurled at the base of a cliff-
corrasion.
2.This forms a wave cut notch.
3.Continued corrasion will cause the
wave cut notch to expand.
4.The rock above the wave cut notch
becomes unstable and collapses into
the sea.
5.The cliff has now retreated.
6.A wave cut platform is left behind-
erosion cannot take place below low
tide.
FORMATION OF A WAVE CUT PLATFORM
14. Draw a diagram that illustrates how a
coastal stack forms.
15. The headland is
made of chalk which
is sedimentary, lines
of weakness run
throughout it.
Between high and
low tide corrasion
occurs.
Corrasion will
continue to
undercut the cliff,
forming a cave.
If two caves are
formed either side
of a headland
corrasion will erode
them backwards till
they meet.
Continued corrasion
undercuts the base
of the arch, it will
collapse to form a
stack.
Continued corrasion
at the base of the
stack will undercut
it; it will collapse to
form a stump.
Hydraulic action will
exploit these
weaknesses, making
the cracks larger.
Corrasion produces
a wave cut notch at
the base of the cliff.
Corrasion evacuates
the cave so it
becomes larger and
deeper.
When they meet an
arch is formed.
Formation of a coastal stack
16. Draw a diagram that illustrates the
formation of a spit.
17. 7. The area behind the spit is
now sheltered encouraging
greater deposition- over time
a salt marsh may form.
6. Occasionally the wind direction may
change- this will also change the
direction of LSD.- this cause the spit to
curve.
‘With the aid of a labelled diagram, explain the
formation of the spit at Blakeney Point.’
4. Here there is a change in direction of
the coastline, this means the sea is quite
calm and shallow.
5. This encourages deposition to occur
and a spit begins to form. LSD can
continue.
3. Material is moved along the beach in
a zig-zag motion- called long shore drift.
1. Direction of the prevailing wind-
North-East.
2. Swash transports material up the
beach. Backwash transports material
down the beach.
8.Here the spit is limited from
developing further by a river- which will
carry material away.

•Long fetch from North-East
•2 metres of erosion per year.
Strategy
•Roll back policy.
•Caravan parks moved 400 metres from the coast.
•New developments must be 30-200 metres from the coast.
•Only major settlements protected.
Mappleton- 450 metres of cliffs protected. 61,500 tonnes of rock
armour, two groynes and sloping revetment.
20. Protecting Against Coastal Flooding
Reasons for increased coastal flooding
• Rising temperatures, leading to melting of land based
ice and thermal expansion.
• Warmer seas leading to more intense tropical storms,
.i.e cyclones, resulting in storm surges and heavy
rainfall.
• Coastlines are densely populated, increasing the ice of
flooding.
Thames Barrier, London - Hard
Engineering
• Open 1983
• Current cost £1.6 billion
• 10 gates raised within 30 minutes to stop storm
surges
• Protects 80 billion pounds of assets
• Protects 12 million people
• No flood in central London since opening
• Will need to be rebuilt in the future – 2030.
Bangladesh- Hard/Soft Engineering
• Afforestation along the coastline
• Development of flood walls in some area
• Public education about living next to the coast
• Early warning system of potential flooding events
• Cyclone shelters
Medberry, West Sussex- Soft
Engineering
• U.K’s largest scheme- £28 million pounds
• Original shingle beach unsustainable- required
maintenance each year- risk increase die to sea
level change. Cost £300,000 a year. Breached 14
times since 1994.
• Sea will be allowed to flood, defences built further
inland. 7km flood wall 2 km inland- protect from 1
in 1000 year flood
• Previous flood in March 2008 caused £5 million
pounds of damage.
• 183 hectares of land.

34. James
I have studied the Peak District. An advantage of tourist going to the area is that they provide jobs
for local people at tourist attractions like Chatsworth House; this means that local people are
employed. If people are employed they are more likely to spend in the local area, this creates more
business for local traders- this is called the positive multiplier effect.
The disadvantage of these jobs are that they are often low paid and seasonal, this means that people
are likely to be out of work in the slower winter months and will need to find alternative employment.
Tourists often travel to the Peak District to walk, but this has created huge areas of erosion along the
Pennine Way. Hundreds of people walking off the paths remove the vegetation; the soil is then
washed away when it rains. As a result vegetation can’t regrow on these areas, this look unsightly.
Tourists thought also provide income that maintains the environment, without tourist receipts
historic locations like Chatsworth House could not be maintained as they are not funded by the
government.

Case study, tomato farming in Ghana
Background Impact on Ghana.
E.U. produces 16 million tonnes of tomatoes each year.
Second only to China.
E.U. provides £250 million pounds of subsidy each year to
tomato farmers in Europe.
The EU currently puts an import tariff of 15% on tomatoes.
The impact of the subsidies is to reduce the cost of tomato
paste and canned tomatoes by 65%.
As a result this makes E.U. tomatoes products cheaper.
The E.U. is therefore a major exporter of tomatoes.
If the subsidy was to be removed, this export market would
collapse.
Imports would increase by 100%.
World prices would increase by 5%.
It currently generates 250 million Euros for the European
economy.
Ghana adds a tariff of 25% for imported tomatoes.
The World Bank has forced Ghana to remove import quotas
on tomatoes into the country, otherwise it wouldn’t receive
loans.
The E.U. subsidies mean that the world price is depressed by
up to 5%.
A European farmer’s tomato is half the cost of a Ghanaian
farmer’s tomato.
Ghana farmers therefore get a very low price for their crop.
As a result their quality of life is poor. Lack of healthcare,
nutrition and education.
Crops are they left to rot in the field, if they can’t be sold.
Domestic consumption has collapsed as Ghanaians purchase
cheaper imports.
The country doesn’t have the factories to process the
tomatoes into secondary products which would command a
higher price.
You could also reuse this
case study as an example
of the impact of trade and
consumer choice.
46. Consumer choices
Food miles Organic shopping
Consumers only purchase food locally. Technically locally is
within 25 miles- this is mostly impossible!
Positives
Reduces carbon footprint of household. Less fossil
fuel used for transport.
Supports local farmers and producers.
Know source of your food and how it has been grown
or reared.
Food is more nutritious, quality hasn’t declined during
transport.
Negatives
Reduced choice.
Food may only be available in season.
LEDC farmers may lose out; they tend to produce
primary foodstuffs.
Food may be more expensive; UK farmers need to
maintain a fair quality of life.
Food may be travelling a shorter distance, but
greenhouses may be needed to grow it within the UK,
therefore increasing the carbon footprint of the
products.
Consumers only buy food produced without the use of
chemicals.
Positives
Reduces carbon footprint of household, no chemicals
need to be manufactured and used during
production.
Chemicals do not leak into the environment,
therefore damaging it.
Food is free from chemical residues. Safer for health?
Some believe the food tastes better.
Many organic farmers tend to be from LEDC
countries; therefore you are supporting their quality
of life.
Negatives
Usually around 10% more expensive.
Tends to be a smaller range of products.
There is no evidence that organic products taste
better, or are better for your health.
70% of organic food is imported, increasing carbon
footprints.
