Using one or more named locations, describe the ways in which the Japanese have attempted to reduce industrial pollution. (6 marks)
The area around Tokyo Bay has a concentration of steelworks and chemical factories. This has led to the pollution of both the air and water. Chemicals such as mercury are released into the water. 1970 Water Pollution Control Law prohibited releasing poisonous wastes into the sea. Sulphur dioxide was released as the result of burning fossil fuels. Problems of air pollution have been overcome by building chimneys taller so that the pollution would enter stronger winds and be carried further and be diluted before settling. Chemical and sprinkler systems are now installed on tops of chimneys to remove the sulphur dioxide. Water sprinklers keep the coal / iron ore piles wet so dust cannot form. ‘green corridors’ of trees have also been planted around factories to trap any dust and to reduce noise and visual pollution.
Bangladesh has a high birth rate for a number of reasons. Firstly there is a high infant mortality rate so families have a large number of babies to ensure that some children survive that not only will be able to work the land but will be able to look after their parents when they get older. It is also important to have a male heir. There is limited knowledge or willingness to practise family planning. Women are not as highly educated as males and they do not have career expectations, their main duty is to marry early and have children. Bangladesh has a young population so there is a large proportion of women of child – bearing age.
UK population hits 60 million

Name of Development project – Vietnam Dyke Project
The building of dykes in Ky Anh Province, Vietnam rice yields were low because farmland was often flooded by the sea and soils became very saline. Oxfam worked with local government and local people to build a sea dyke 11 miles long which means that areas of farmland can be drained and protected from flooding. There is therefore an increase in farmland. This could be used to grow food crops like rice as well as cash crops which can be sold. People are better fed and they also have money from the sale of cash crops. Roads have also been built to improve communications and trade. This long term project is sustainable because it taught the people new skills. These skills allowed them to undertake other building work. They were also able to teach these skills to others and their children. It uses low cost technology such as hand tools. Any surplus rice crop can be taken to market along the new roads, so increasing the farmers’ income.
Level 1 (Basic) 1-2 marks
Simple statements, with lifts from Figure 8, or with no indication of why the scheme in Stoke-on-Trent is better than comprehensive redevelopment.
The area has been landscaped and there are places for the toddlers to play. Roads have been improved. Renovation is cheaper.
Level 2 (Clear) 3-4 marks
Linked statements, which show how urban renewal is better than slum
With comprehensive redevelopment people would have to be moved away from the area where they had lived for a long time and there would be a loss of community spirit. With urban renewal however, people could stay in the area and the houses would have been modernised and improved for example with new bathroom facilities or new roofs. The general environment is also improved making it a more pleasant area in which to live for example ‘green’ areas are provided through landscaping and play areas are provided for young children. (4 marks)
Why can gentrification be considered a disadvantage to some people living in inner city areas? (1 mark)
•The price of houses would go up and the local people may not be able to buy in the area any more.
•There may be some change of service provision in the area e.g. a pub might become a wine bar.
•These changes might lead to social divisions within the area.
Name the large urban area you have studied. Compare your chosen large urban area with the model in Figure 2 (Burgess concentric zones model). You must refer to examples of streets / districts in your answer. (4 marks)
Level 1 Basic (1-2 marks)
No reference to named example or basic description of the area with no reference to the model.
New Street, Colmore Row and Broad Street are in the centre of Birmingham. The next areas are Highgate and Sparkhill and then come Hall Green. The furthest out is Monkspath. In the centre are shops and offices. Then come poor housing and nearer the edge are better class housing.
Level 2 Clear (3-4 marks)
Some indication of where the urban morphology fits or does not fit perfectly into the simple concentric model of Figure 2. Need to refer to at least 2 urban zones for full marks. Maximum mark only if some comparison made to urban model.
Birmingham is an example of a city that generally fits into the concentric zone model. The CBD is found in the centre of the city and has all the typical features of a CBD. New Street is the centre of the retail area, Colmore Row is the main financial area and Broad Street is one of the main entertainment areas in the CBD. Birmingham’s CBD is surrounded by the Inner City areas as identified in the model. Highgate is an inner city area that had been redeveloped and there is now a mixture of both industry and lower quality housing. Sparkhill is another inner city area although this area is more traditional with rows of 19th century terraced housing that have now been improved and gentrified. One area that does not fit the circular model is Edgbaston/ Harborne. This area is close to the CBD however is chararcterised by expensive 19th housing that was originally owned by industrialists. The houses tend to be large detached houses. Housing is newer as you move outwards, for example the outer suburb of Monkspath is newer than the inner suburb of Hall Green. Monkspath is dominated mostly by modern, high class detached and semi detached housing and Hall Green is characterised by interwar semi detached housing. Another area that does not fit the concentric model is Chelmsley Wood. This is a housing estate found on the edge of the city.
Level 1 Basic (1-2 marks)
•Simple statements are made.
•There are more jobs and more medical facilities etc in cities so people move there.
•Natural disasters and infertile soils in the countryside cause people to move to the cities.
Level 2 Clear (3-4 marks)
•Need both push and pull factor(s). For full marks there needs to be some evidence that the candidate recognises that the question asks for reference to a specific country.
•People move from rural areas due to push factors, for example, the floods in Bangladesh cause loss of food and this means that people in the countryside move to the urban areas of Calcutta or Dhaka. The pull factors from these urban areas also include the expectation of more varied and regular work with higher pay, improved housing and sanitation and more hospitals and doctors.
1. ABRASION. As a glacier moves, the rocks frozen into its base and sides scratch the valley bottom and sides and wear (erode) it. It has a sandpaper effect so the eroded rock looks smooth.
2. PLUCKING. When a glacier is not moving it tends to freeze itself to the valley sides. If the glacier then starts to move it will tear lumps of rock out of the valley sides. This happens a lot at the backwall (headwall) of the glacier.
3. Ribbon lakes(finger lakes) are often found on the floor of a U-shaped valley (glacial trough). Describe three ways in which a ribbon lake is formed.
1. If a valley floor contains both hard and soft rocks the glacier will erode deeper into the softer rock. This eroded hollow may the fill with water to create a lake.
2. Where a tributary glacier joins a main valley glacier the extra weight of ice will erode downwards more at this point. This deeper hollow may then fill with water to create a lake.
3. When a glacier reaches lower ground it will start to melt in the higher temperatures. As it melts it deposits rock debris contained in the ice. This deposited rock forms a bank of rock called a terminal moraine across the valley floor. This can act as a dam and a lake can form behind it.
INPUTS. These are the factors which are put into the industry e.g. raw materials, fuel, labour and transport.
PROCESSES. These are the jobs done with the inputs e.g. processing of materials, assembling parts and packaging the finished item.
OUTPUTS. These are the finished products e.g computers, cars, clothes and chemicals.
2. Explain why hi-tech industry has grown up along the M4 corridor.
This industry has developed in places like Bristol and Reading on the M4. Land here is cheaper than in London further to the east, but access to London is easy and fast. Some of the products are exported by air so closeness to Heathrow airport on the western side of London is important. There are fast road links for deliveries to other parts of Britain via the M4,M5,M40,M25 and M3. Hi –tech products are light and easily/cheaply transported by road. Bristol and Reading are university towns which can supply skilled workers and undertake research and development of new products.

Abrasion - A glacial erosion process. When blocks of rock debris are trapped on the underside of a glacier and then, as the glacier moves, this has a sand paper effectwearing away the base and sides of the valley.
Arete - a knife edge ridge that separates two corries e.g. Striding Edge
Corrie - an arm chair shaped depression formed on the side of a mountain e.g. Red Tarn
Frost shattering - a weathering process. Water gets into cracks in the rock. When the tempreature drops beloow zero, the water freezes and expands exerting pressure on the sides of the crack. Eventually the crack is widened and the rock disintegrates.
Glacial trough - U - shaped valley which has been widened and deepened by a valley glacier e.g. Patterdale
Glacier - a mass of moving ice
Plucking - A glacial erosion process. Water enters cracks in the rock and freezes so that it is attached to both the rock and the glacier. When the glacier moves, the block of rock is pulled out of the ground.
Ribbon Lake - a long thin, deep lake on the floor of a glacial trough e.g. Thirlmere
Rural to urban migration
Think PUSHED for Push factors
P - pressure on land so many have to leave
U - unemployment in the countryside
S - sanitation - poor or non-existent in rural areas. Often no running water or clinics
H - hardship - often a harsh climate
E - education - little if any
D - disasters, drought, famine, civil war etc
B - better paid jobs or perceived better job opportunities, factory jobs which are not dependent on the weather
E - education provision is better
P - perception that city life is better
H - More provision of health care

- air and noise pollution
- health problems
- greater demands on car parking
- heavy congestion
- commuter traffic - twice daily build up
- danger to pedestrians
- vehicle vibrations can cause damage to old buildings
- cost of road maintenance
- old buildings cleared to make way for new roads
1. reduce the amount of traffic entering the urban area: - traffic free zones, park and ride schemes (Cambridge, Stratford upon Avon), inner and outer ring roads (Birmingham), bypass, motorways, M6 Toll, congestion charges (London)
2. encouraging people to use public transport: - reliable and frequent bus service, fare reductions (e.g. season tickets), bus only lanes so public transport is faster, installing new rapid - transport systems (Manchester Metro)
3. Reducing air pollution from vehicle exhausts by:- enforcing law on vehicle emissions
using traffic control methods: traffic lights
Case Study - Birmingham
In Birmingham, there have been major traffic problems in the past, particularly around the main routes into the city centre. In order to tackle this, Birmingham City Council have taken a number of measures. In the North they have turned the A38 into a tidal flow road, which is now known as the Aston Express Way. This allows them to change the number of lanes entering and leaving the city to cope with the rush hour. In addition there is also an urban motorway with up to 8 lanes for traffic to cope with the volume. In the East the Stratford Road is now a red route, which means that there is no stopping allowed along this stretch of road and thus maintains the flow of traffic. The main heart of the CBD around New Street, is pedestrianised with bus lanes all around the edge of the CBD. This allows commuters to reach the centre easily and quickly whilst keeping them safe. To the West of Birmingham a rapid transit system (trams) has been set up running from the Black Country into Snow Hill Station, in the business area of the CBD. This is a park and ride scheme aimed at commuters and runs every 10 minutes during the week. There has been major investment in the public transport network with Travel West Midlands offering integrated timetables linking bus routes with trains. All prices on public transport are kept below £1.00 per journey to encourage people to use it. The road network is well organised with both an outer and inner ring road keeping traffic away from the city centre. In 2003 the M6 Toll Road was opened which takes traffic away from the motorways around the edge of Birmingham in order to reduce pressure and congestion on these roads.

The movement of people out of urban areas (e.g. inner city areas) into a more rural environment (suburbs)
Why do people want to move away from the more urban areas: (PUSH FACTORS)
- higher density housing
- little space
- less room
- poor quality housing
- higher crime rates
- more congestion
- higher levels of air and noise pollution
- both shopping and industry are tending to move towards outskirts
Why are people attracted to the more rural areas? (PULL FACTORS)
- more spacious
- better quality of housing with more modern amentities, double glazing, detached properties, front and back gardens, garages, utility rooms
- bigger houses and gardens
- safer for children
- less congested
- improved transport makes commuting possible
- more attractive environment close at hand
- new residential estates
- closer to modern industrial estates set up in rural fringe
- less air and noise pollution
Effects of out-migration on the more urban areas:
- less people
- derelict land as industry moves out
- elderly and unemployed people left behind
- loss of 'community spirit
- older housing becomes more run down, empty houses are boarded up
- shops close due to less custom
- less government investment
Effects of in-migration on more rural areas
- pressure for more new housing development
- rise in house prices (young cannot afford homes and move away)
- schools become more overcrowded
- more pressure on local services - doctors
- locals swamped by newcomers - friction
- becomes busier, area looses its charm
1. Cheap to acquire
road and rail routes converge
high land values leading to tall buildings
competition for land
shops, high order, large departmental stores and specialist shops
banks and offices
often central area is pedestrianised
congested with traffic and people
Commuter – a person who lives in one settlement and travels daily to work in another settlement.
Commuter village – a village where a large number of the residents travel to work each day in another settlement and then return each evening
Comprehensive redevelopment - the rebuilding of housing and industry together with roads and environmental improvements
Gentrification – Professional people return to live close to the city centre by buying up older substandard housing which is then substantially improved.
Green belt – the area of land around a large urban area where the development of housing and industry is restricted and the countryside is protected for farming and recreation
Housing renovation – The improvement of homes by adding inside bathrooms, toilets, central heating etc.
Inner city – The area occupied by 19th century factories and terraced housing
Migration – the movement of people, either voluntary or forced, between or within countries
Out of town shopping centre – A retail park built in the countryside on the edge of a town –e.g. Merry Hill
Retail park – A group of large one storey shops with car parks built close to a major road,
Rural – urban fringe – area between the built up area and the countryside where there is often competition for land use e.g. golf courses, business parks, residential homes
Shopping centre – A group of shops
Slum clearance – the removal of old and decayed housing
Suburb – the outer, usually, residential area of a town or city
Suburbanisation – The growth of housing and population in the outer areas of a town
Twilight zone – The area of decay between the CBD and the inner city
Urbanisation – When the percentage of the population living in towns within a country increases
Urban morphology – the pattern of land use in a town
Large flat site in areas of low population density and where land is of little agricultural value - cheap
Access to gas fields – e.g. North Sea
Close to river for cooling water and als water needed to produce steam for generation
COAL - located on coalfields, close to collieries and existing open cast coal mines e.g. Selby, Case Study: Eggborough Humberside
Large flat site
Built on or near large supplies of coal (mine) because it is bulky and very expensive to transport
Often linked to pits by special railways that only carry coal. By locating close to mine and building rail links, transport costs are reduced
Located along major rivers because large amounts of water are needed to produce steam to drive turbines and need large amounts of cooling water
Many are near to urban areas many of the large conurbations developed on the coal fields during the time of the industrial revolution
NUCLEAR - scattered locations around the country. Case Study Heysham, Lancs
Located away from large populated areas in case of accidents and also as there is less opposition to building plant
Large, flat site
Low value land
Located on the coast as vast amounts of water are needed for cooling purposes
Good transport links for both raw materials and waste products
WIND - farms - majority are located in west of country, in upland areas. No wind farms in National Parks. Case Study Lambrigg wind farm, Cumbria
Areas with high and regular wind speeds so often found in exposed coastal locations or in remote upland areas
The wind speeds are higher in the west of the country
In Britain there are more days when winds blow from the west than from any other direction so there are more days when the wind turbines can be operated.
At higher altitudes, wind speeds are faster and there are fewer obstacles to block the wind.
Wind farms are not built where they would detract from the natural beauty of a National Park
HEP - Found mainly in the north and west of the UK in upland areas. Case Study: Cruachan W. Scotland
Large and regular rainfall (> 1500mm pa) and low rates of evaporation in order to provide a constant supply of water.
Upland areas where narrow valleys which are ideal for dam construction and water storage
Strong and impermeable bed rock so water does not drain away through the rocks
Cheap land, sparsely populated
Steep upland gradients or former waterfall to give the necessary high head of water to turn the turbines
Fossil Fuel - Non renewable forms of energy formed through past organisms, coal, oil, natural gas. When burnt, these release carbon
Hydro electric power - The use of falling water to turn a turbine to generate electricity
Non-renewable energy - A fuel source which can only be used once before it is exhausted because it takes millions of years to form
Renewable energy - A source of fuel which can be used over and over again, e.g. wind, solar
Thermal power station - Power stations which use heat to make steam which turns the turbines to generate electricity. The heat can be made from the burning of coal, oil or gas or alternatively from nuclear reactions or use of geothermal activity.
Gas - Advantages
More efficient to burn and easier to transport and distribute (by pipeline and tanker) than coal. Cleaner, cheaper and less harmful to the environment than coal.
Safer than nuclear energy.
Gas - Disadvantages
It is a fossil fuels so adds to global warming and the creation of acid rain.
It is a non-renewable resource so supplies will eventually run out.
Coal - Advantages
Reserves are likely to last for over 300 years.
Improved technology has increased the output per worker, allowed deeper mining with fewer workers and made conversion to electricity more efficient.
Coal also used for heating and making coke.
Coal - Disadvantages
The most easily accessible deposits have been used up and production costs have increased.
There is increasing competition from other types of energy.
It is a fossil fuel and so contributes to global warming and the creation of acid rain.
Deep mining can be dangerous, while opencast mining temporarily harms the environment.
Coal is heavy and bulky to transport.
Nuclear - Advantages
Only very limited amounts of raw materials are needed, e.g. 50 tonnes of uranium per year compared with 540 tonnes of coal per hour needed for coal-fired stations.
Safeguards make the risks of accidents minimal.
Reserves of uranium will last much longer than those of coal and gas.
Waste is limited and can be stored underground.
Nuclear power is believed to contribute less than coal and oil to the greenhouse effect and acid rain.
Nuclear - Disadvantages
It is not clear how safe nuclear power is.
Conservationists argue that one accident may kill many, and ruin an area of ground for hundreds of years.
There are potential health risks. The high incidence of leukaemia around Sellafield and Dounreay has been linked to proximity to nuclear power stations.
Nuclear waste can remain radioactive for many years.
The cost of decommissioning old power stations is extremely high.
HEP - Advantages
Hydro-electricity is renewable and is often produced in highland areas where the population is sparse.
It is a relatively cheap form of power and creates little pollution.
Dams built to store water for HEP production can also reduce risks of flooding and water shortages.
HEP - Disadvantages
Dams are very expensive to build.
Large areas of farmland and wildlife habitats may have to be flooded forcing people and animals to move.
Unsightly pylons can cause visual pollution and there is the
Possibility of the dam collapsing.
Silt, previously spread out over farmland, will be deposited in the lake.
More recently, it has been shown that if an area is flooded, the decaying vegetation can release methane and carbon dioxide - two greenhouse gases.
Limitless in supply
Solar - Disadvantages
Technology to build cheap efficient solar power stations has not yet been developed
In countries such as the UK, capability to produce large amounts of solar energy is greatly reduced in the winter, when daylight is shorter and the sun is at a low angle in the sky
Need a large number of panels for small amount of energy
Capable of being developed commercially in the UK
Safe, clean (no radioactive or chemical emissions) and does not contribute to global warming or acid rain
Has a minimal effect on local ecosystems
Winds are stronger in winter when demand for electricity rises
After the initial construction electricity production is relatively cheap
Wind farms provide a source of income for farmers and may attract industry in isolated rural areas
Future wind farms are likely to be built offshore
Wind - Disadvantages
Expensive to build and maintain. Around 7000 turbines needed to produce the same amount of electricity as 1 nuclear power station. As many as 100 000 wind farms may be needed if UK is to generate 20% of its total energy from wind
Wind does not blow all the time
Wind farms spoil scenic countryside and areas
Wind farms are noisy and can interrupt radio and TV signals for people living nearby. Affect property values
Still an expensive and not very efficient way of producing electricity

Growing of crops
Large scale, capital intensive farms that specialise in only a few crops and use scientific advisers and techniques together with business principles to produce the maximum yields and quality. Often tied to supermarkets or processors to buy the crops
The number and variety of plant and animal species found in an ecosystem
Large capital investment in machinery, chemicals etc to maximise outputs
Common Agricultural Policy
The E.U policy on farming. By guaranteeing prices on many foodstuffs, CAP ensures that farmers earn enough money to be able to make a decent living and invest in their farms.
The system, of growing a sequence of crops in strict rotation in the same field in order to maintain soil fertility
Farmers are encouraged to find new ways of using their land
Economies of scale
Cost savings made by production on a large scale
Chemicals (particularly nitrogen and phosphorus) from fertilisers seep into streams etc. Here it causes rapid growth of algae which blocks sunlight. Oxygen is used up and stream life begins to die.
Land left unseeded after being ploughed and harrowed to regain fertility
Chemicals which add nutrients to the soil to replace those that the crops take out
Food mountains and lakes
Mountains – grain, butter, beef
Money which is given to a farmer to cover cost of farm improvement
Chemicals which kill weeds which might compete with the crops for nutrients and sunlight
Chemicals which kill insects which might eat crops or damage them
There are large inputs to each hectare in order to produce large outputs of crops
A system of farming which requires a heavy amount of hand labour
An area of land temporarily under grass
Farming involving both animals and crops
Production of a single crop
Farming which rears only animals
Chemicals which kill pests such as fungus which can damage crops during growth.
A set amount of food which a farmer is allowed to produce
A policy whereby farmers leave some land unused and receive a payment in compensation
Money given to farmers when the market price for their produce is low. This ensures that farmers do not make a loss.
Overproduction of certain crops which need to be stored
Lakes – overproduction of liquid farming products: olive oil, wine, milk

Abrasion (Corrasion) : Wearing away of the bed and banks due to the action of water and the load. Sand paper effect.
Attrition: The wearing down of rocks and pebbles into smooth rounded particles due to transport by the river.
Hydraulic action: Force of the running water erodes the banks of the river.
Solution (corrosion): The water dissolves particles in the rocks
River Transport Definitions:
Saltation: Sand sized particles are bounced along the river bed
Solution: The water dissolves material
Suspension Small clay sized particles are carried along in the flow of water
Traction: Large boulders are rolled along the bed of the river
Hydrological cycle terms:
Condensation: Process whereby water vapour changes to water liquid
Evaporation: The process whereby water liquid is turned through heat into water vapour
Groundwater: Water underground which has collected from the downward movement of water through the soil and rocks
Impermeble rocks: A rock which does not allow water to pass through
Infiltration: The downwards movement of water through the soil laters
Interception: Trees and vegetation blovck the path of rainfall to the ground
Percolation: Downwards movement of water through the rock
Permeable rock: A rock which does allow water to pass through due to spaces between grains
Precipitation: The deposition of moisture on the Earth's surface - rain, sleet, snow and hail
Stemflow: Water flows down through stems and branches
Transpiration: The process whereby vegetation fives off moisture to the atmosphere
General River basin terms:
