The Restless Earth Coasts The Living World Urban Environments Tourism Population Change Command Words: What is the question asking you? Look for key words and do exactly what has been asked. e.g.: Annotate: - add notes or labels to a map or diagram to explain what it shows. Compare: - Look at 2 (or more) things and state the similarities and differences. Make direct comparisons and use appropriate link words such as more than, less than, larger, whereas, unlike, as opposed to, as well as opposites such as, rural/urban, high/low, etc. Complete: - add to a map or graph to finish it off. Contrast: - look for the differences between features or places. Often the question will ask you to compare and contrast. Define: - explain what something means e.g. hydraulic action. Describe: - State what it is like; its characteristics and appearance. Draw: - a sketch map or diagram with labels to explain something. Explain or Account for: - Make clear, give details why it is like that. Identify: - name, locate, recognise or select a particular feature or features, usually from a map, photo or diagram. Mark: - put onto a map or diagram. Name, state, list: - give accurate details or features. Study: - look carefully at a map, photo, table, diagram etc. and say what it shows. With reference to /refer to examples you have studied: - give specific details (dates, specific names, facts & figures) about your case studies. With the help of/using the information provided: - make sure you include examples from the information, including grid references if it is a map. Top Hints! 1. Read all the questions 2. Understand the questions. Reading them and understanding them is not always the same. Make sure that you carefully read the question and discover what is being asked of you. Look for words like how, why, where, what and when. Check also for details like features and locations. If you're asked for a UK case study, you will lose marks if you write about a French one. Likewise, if the theme of the question is coasts, resist the temptation to write about rivers. Look for command words such as describe, contrast, compare and explain, then make sure that your answer does what has been asked. 3. Think, then write. 4. Write clearly and Logically. Don't waffle and try to fill space for the sake of it. Write clear sentences in a well-structured answer. Follow a logical sequence of events, but don't panic! Use your connectives, key words, and use PEE 5. Talk the talk. The examiner will be looking for geographical words in your answers. There are marks available for using the right words. Using good geographical terminology shows that you know what you are talking about, that you understand what the specialist terms mean, and will impress the examiners. In short, it will help you to get more marks.

Richter Scale A logarithmic scale used for measuring earthquakes based on scientific recordings of the amount of movement Seismic waves generated by an earthquake that pass through the earth's crust A means of describing earthquakes by describing and comparing the damage done on a scale of I to XII A wave where the entire depth of the sea or ocean is set in motion by an event, often an earthquake which displaces the water above Fissures Earthquake Shock Waves Mercalli Scale Tsunami Type of Boundary The structure of the Earth 1. Explanation Constructive When two plates move away from each other creating a gap between them. Molten rock (magma) rises from the mantle to fill the gap forming a mid-ocean ridge Destructive When an oceanic plate and a continental plate move towards each other the denser oceanic plate dives under the lighter continental one creating a deep ocean trench. As the oceanic plate goes deeper into the mantle, increased temperature and friction cause it to melt creating a subduction zone. Newly molten rock is lighter than the surrounding rock so it rises through the crust towards the surface. If molten rock (magma) reaches the earth’s surface it may spread out along a fault line or it may erupt at a single point as a volcano. When two tectonic plates slide past each other without creating or destroying any land they form a conservative plate boundary. The plates often get stuck as they try to move past each other due to friction. Over time this builds up great pressure until finally they jolt past each other. The sudden movement causes an earthquake which may be violent and cause great damage The inner core is in the centre and is the hottest part of the Earth. It is solid and made up of iron and nickel with temperatures of up to 5,500°C. With its immense heat energy, the inner core is like the engine room of the Earth. 2. The outer core is the layer surrounding the inner core. It is a liquid layer, also made up of iron and nickel. It is still extremely hot, with Conservative temperatures similar to the inner core. 3. The mantle is the widest section of the Earth. It has a diameter of approximately 2,900 km. The mantle is made up of semi-molten rock called magma. In the upper parts of the mantle the rock is hard, but lower down the rock is soft and beginning to melt. 4. The crust is the outer layer of the earth. It is a thin layer between 0-60 km thick. The crust is the solid rock layer upon which we live. Richter Scale The power (magnitude) of an earthquake is measured on the Richter scale, using an instrument called a seismometer. The Richter scale is numbered 0-10 with 10 being the most powerful. The Richter scale is logarithmic – an earthquake measuring 7 is 10 times more powerful than one measuring 6 and 100 times more powerful than one measuring 5. Mercalli Scale The Mercalli scale measures the damage caused by an earthquake. The Mercalli scale goes from I to XII – I would not be felt but XII would be total destruction.

A promontory of land jutting out to sea Bay A broad coastal inlet often with a beach Wave-cut Platform A wide, gently sloping rocky surface at the foot of a cliff Wave-cut Notch A small indentation cut into a cliff roughly at the level of high tide caused by concentrated marine erosion at this level A hollowed-out feature at the base of an eroding cliff A headland that has been partly broken through by the sea to form a thin-roofed arch An isolated pinnacle of rock sticking out of the sea A finger of new land made of sand or shingle, jutting out into the sea from the coast Low-lying coastal wetland mostly extending between high and low tide Building artificial structure such as sea walls aimed at controlling natural processes A sustainable approach to managing the coast without using artificial structures Cave Arch Stack Spit Salt Marsh Hard Engineering Soft Engineering Constructive Waves They are created in calm weather and are less powerful than destructive waves. They break on the shore and deposit material, building up beaches. They have a swash that is stronger than the backwash. They have a long wavelength, and are low in height. Process Description Solution Minerals are dissolved in sea water and carried in solution. The load is not visible. Load can come from cliffs made from chalk or limestone, and calcium carbonate is carried along in solution. Suspension Saltation Traction Small particles are carried in water, eg silts and clays, which can make the water look cloudy. Currents pick up large amounts of sediment in suspension during a storm, when strong winds generate high energy waves. Load is bounced along the sea bed, eg small pieces of shingle or large sand grains. Currents cannot keep the larger and heavier sediment afloat for long periods. Pebbles and larger sediment are rolled along the sea bed. Destructive Waves Destructive waves are created in storm conditions. They are created from big, strong waves when the wind is powerful and has been blowing for a long time. They occur when wave energy is high and the wave has travelled over a long fetch. They tend to erode the coast. They have a stronger backwash than swash. They have a short wave length and are high and steep. The Formation of a Wave-cut Notch 1. Weather weakens the top of the cliff. 2. The sea attacks the base of the cliff forming a wave-cut notch. 3. The notch increases in size causing the cliff to collapse. 4. The backwash carries the rubble towards the sea forming a wave-cut platform. 5. The process repeats and the cliff continues to retreat. Long Shore Drift Waves can approach the coast at an angle because of the direction of the prevailing wind. The swash of the waves carries material up the beach at an angle. The backwash then flows back to the sea in a straight line at 90°. This movement of material is called transportation. Continual swash and backwash transports material sideways along the coast. This movement of material is called longshore drift and occurs in a zigzag. Spit Formation 1. Longshore drift moves material along the coastline. 2. A spit forms when the material is deposited. 3. Over time, the spit grows and develops a hook if wind direction changes further out. 4. Waves cannot get past a spit, which creates a sheltered area where silt is deposited and mud flats or salt marshes form.

The CBD is usually found in the middle of the city so that it is easily accessible. The area around the CBD – usually built before 1918 in the UK The area on the edge of the city. Many suburbs were built after 1945 and get newer as they reach the edge of the city. Brownfield Sites Land that has been built on before and is to be cleared and reused. These sites are often in the inner city Greenfield Sites Land that has not been built on before, usually in the countryside on the edge of built up areas. Urban Development Set up in the 1980s and 1990s using public funding to buy land and Corporations (UDCs) improve inner city areas, partly by attracting private investment. City Challenge A strategy in which local authorities had to design a scheme and submit a bid for funding, competing against councils. Sustainable Community A community (offering housing, employment and recreation) that is broadly in balance with the environment and good quality of life Segregation Occurs where people of a particular ethnic group choose to live with others from the same ethnic group, separate from other groups. Squatter Settlements Areas of cities (usually on the outskirts) that are built by people of any materials they can find on land that doesn’t belong to them. Informal Sector That part of the economy where jobs are created by people to try to get an income and which are not recognised in official figures. Self-Help This is where local authorities help the squatter settlement residents to improve their homes by offering finance in the form of loans or grants and often installing water sanitation etc. Site and Service Occur where land is divided into individual plots and water, sanitation, electricity and basic track layout are supplied before any building by residents begins. Industralisation A process in which an increasing proportion of the population are employed in the manufacturing sector of the economy. Landfill A means of disposing of waste by digging a large hole in the ground and lining it before filling it with rubbish. Sustainable City An urban area where residents have a way of life that will last a long time. The environment is not damaged and the economic and social fabric, due to local involvement are able to stand the test of time. Urban Model in a Rich Country Urban Model in a Poor Country CBD Inner-City Outer-City Suburbs Rural-Urban Fringe Managing Traffic Park and ride schemes Cycle lanes Congestion charging schemes, such as those in Durham and London Car-pooling, as used in the USA, to encourage people to share cars Low Emission Zones, as in London Brownfield Sites Are often on disused and derelict land. Are more available in the North and Midlands (but Greenfield sites This includes the greenbelt land around cities. most housing demand is in the south east). Are cheaper to build on. Are valuable as existing buildings can be split up Are not favoured by environmentalists, as it into more homes on any one site. The site has already been developed so reduces urban sprawl. Are sites which have not previously been built on. encourages urban sprawl. Encourage commuting and traffic congestion as people travel into urban areas from the countryside. Use unsightly areas for building developments, so improves the urban environment. Are found in urban areas, so building housing there reduces demand on car use. Are more expensive to build on as often the land needs to be cleared first (especially if land is contaminated from previous industrial use) Problems in Shanty Towns Overcrowding - the settlement has a high population density. Fires - fires can spread quickly. Overpopulation - the area does not have enough resources to support the growing population. Competition for jobs - jobs are in short supply. Disease - poor sanitation and limited health care can lead to the spread of disease. Lack of space - the newest and poorest arrivals may be forced to live on the worst quality land. Infrastructure - services are poor, public transport is limited and connections to the electricity supply can be limited and sometimes dangerous.

Exploration - a small number of tourists visit the area. The area is unspoilt and few tourist facilities exist. 2. Involvement - local people start to provide some facilities for tourists. There starts to become a recognised tourist season. 3. Development - the host country starts to develop and advertise the area. The area becomes recognised as a tourist destination. 4. Consolidation - the area continues to attract tourists. The growth in tourist numbers may not be a fast as before. Some tensions develop between the host and the tourists. 5. Stagnation - the facilities for the tourists may decline as they become old and run down. The numbers of tourists may decline too. 6. Rejuvenation - investment and modernisation may occur which leads to improvements and visitor numbers may increase again. 7. Decline - if the resort is not rejuvenated (stage 6) then it will go into decline. People lose their jobs related to tourism. The image of the area suffers. Advantages of Tourism in the Lake District Tourism provides employment and income for local people. People choose to stay in the area, which maintains other essential services such as schools and hospitals. Services provided for the use of tourists - eg leisure facilities - also benefit local people. Disadvantages of Tourism in the Lake District Employment can be seasonal and wages low. House prices in the area can rise due to a demand for second homes. School leavers often look for work in larger settlements due to low wages and high house prices. This causes rural depopulation. Local shops on the margins of profitability often close to make way for more profitable gift shops and tea rooms. This leaves local people without essential services, eg butchers and greengrocers. Traffic causes pollution and narrow roads can become congested in high season. Large numbers of hikers cause footpath erosion, which is expensive to repair. Watersports cause erosion of lake shores and there can be conflicts of interests between different lake users Tourism in Antarctica The Living World Content Concept of an ecosystem, A small scale ecosystem, how it works (e.g. a hedge row) Consumers, decomposers, food chain/food web and producers – the balance between the components Global distribution of temperate deciduous forest, tropical rainforest and hot deserts: characteristics of each one – vegetation, climate and soils How plants adapt to the conditions in each of the 3 ecosystems Case study of temperate deciduous woodland: how used?

Nature tourism usually involving small groups with minimal impact on the environment Many poorer countries are in debt, having borrowed money from developed countries to support their economic development. There is stron international pressure for developed countries to clear these debts. The deposition of solid salts on the ground surface following evaporation of water Subsistence Farming Farming to produce food for the farmer and his/her family Food Webs Each level of a food chain is known as a trophic level. Food chains and food webs show the feeding relationships in a community. But they do not tell us how many living organisms are involved. It takes many plants to feed a herbivore, and many herbivores to feed one carnivore. A food web is a set of interconnected food chains by which energy and materials circulate within an ecosystem. Cacti have never lost their leaves completely; they have only reduced the size so that they reduce the surface area through which water can be lost. Cacti have also developed spines which allow less water to evaporate through transpiration by Adaptations shading the plant, and defend the Tropical Rainforests cactus against water-seeking animals. The three-toed sloth is almost totally arboreal ("tree-dwelling"), with a body "built to hang." It lives in the shrub layer, but sometimes moves to the canopy. Its long, coarse fur often appears green, not due to pigment but due to algae growing on it. The sloth’s greenish colour and its sluggish habits provide effective camouflage: hanging quietly, the sloth resembles a bundle of leaves.

Push Factor Something that makes people want to leave an area e.g. poor health care Pull Factor Something that attracts you to an area e.g. a good job Population density The Demographic Transition Model Population density is the average number of people per square kilometre. It is a way of measuring population distribution and shows whether an area is sparsely or densely populated. Population density is calculated using the following formula: Population density = total population ÷ total land area in km² Stage 1: Total population is low but it is balanced due to high birth rates and high death rates. Stage 2: Total population rises as death rates fall due to improvements in health care and sanitation. Birth rates remain high. Stage 3: Total population is still rising rapidly. The gap between birth and death rates narrows due to the availability of contraception and fewer children being needed to work - due to the mechanisation of farming. The natural increase is high. Stage 4: Total population is high, but it is balanced by a low birth rate and a low death rate. Birth control is widely available and there is a desire for smaller families. Population Pyramid for the UK Stage 5: Total population is high but going into decline due to an ageing population. There is a continued desire for smaller families, with people opting to have children later in life. The one-child policy The one-child policy, established in 1979, meant that each couple was allowed just one child. Benefits included increased access to education for all, plus childcare and healthcare offered to families that followed this rule. Problems with enforcing the policy: Those who had more than one child didn't receive these benefits and were fined. The policy was keenly resisted in rural areas, where it was traditional to have large families. In urban areas, the policy has been enforced strictly but remote rural Population Pyramid for Mozambique areas have been harder to control. Many people claim that some women, who became pregnant after they had already had a child, were forced to have an abortion and many women were forcibly sterilised. There appears to be evidence to back up these claims. Impact of the policy The birth rate in China has fallen since 1979, and the rate of population growth is now 0.7 per cent. There have been negative impacts too - due to a traditional preference for boys, large numbers of female babies have ended up homeless or in orphanages, and in some cases killed. In 2000, it was reported that 90 per cent of foetuses aborted in China were female.
