KS3 Geography Knowledge: Tectonic Hazards Natural Hazard A natural process that poses a threat to people and property. If it poses no threat to humans it is called a natural event. Meteorological hazard A hazard that occurs in the atmosphere (e.g. hurricane, thunder and lightening, tornado, drought) Hazard risk There is a higher risk if…. The probability that a natural hazard occurs.

  • It occurs in an urban area due to the higher population density.
  • It occurs in an LIC as they have poor quality buildings and less planning and prediction strategies.
  • Type of hazard: e.g. earthquakes are much harder to predict than tropical storms, floods occur more often than volcanic eruptions. Layers of the earth There are four layers of the earth: the inner core, outer core, mantle and crust. Tectonic Plates The crust is split into several pieces (like a cracked egg shell). These pieces of rock are called tectonic plates. They float on the mantle. Oceanic Crust Crust found under the oceans (thinner, younger, more dense, basalt) Continental Crust Crust found under land (thicker, older, less dense, granite) Continental Drift Theory that said the earth’s continents are very slowly moving in different directions. Convection currents Convection currents are circular currents in the mantle that cause the overlying plates to move. Plate boundary/ plate margin The line between the two plates. This is also known as a fault line. Subduction Goes underneath. Subduction zone The point at which the more dense is subducted beneath the less dense plate. Plate Margin Description Example Destructive Plate Margin Tectonic hazards at a destructive margin: Two plates move towards each other due to CONVECTION CURRENTS in the mantle. The more dense plate is SUBDUCTED beneath the less dense plate. The point of subduction is known as the subduction zone.
  • Volcanoes – as the more dense plate sinks into the mantle, it melts forming magma. This rises up through the crust until it reaches the surface = violent eruptions.
  • Earthquakes – as the more dense plate sinks beneath the less dense plate, pressure builds up. When this pressure is suddenly released it causes explosive earthquakes. The Nazca oceanic plate is being subducted beneath the South American continental plate. Constructive Plate Margin Tectonic hazards at a constructive margin: The plates move away from each other due to convection currents in the mantle. This leaves a gap. Magma rises to fill this gap, creating volcanoes. The lava that is erupted creates new land. This usually happens under the oceans. The continued CREATION OF NEW LAND and movement of plates results in SEA-FLOOR SPREADING.
  • Volcanoes – magma rises to the surface to form volcanic eruptions, however there is little pressure = gentle eruptions.
  • Earthquakes – as the magma rises, small tremors occur = gentle earthquakes. The North American and Eurasian plates are moving away from each other. This has created the Mid Atlantic Ridge in the middle of the Atlantic Ocean. This ocean is getting larger by 2cm/yr Conservative Plate Margin Tectonic hazards at a conservative margin: Two plates move past each other due to convection currents in the mantle. They can move in the same direction at different speeds or in opposite directions. The line between the two plates is called the FAULT LINE.
  • No volcanoes (there is no subduction or creation of magma)
  • Earthquakes – as the two plates slide past each other, pressure builds up. This is suddenly released, it causes violent earthquakes The North American and Pacific plates are sliding past each other. They are moving in the same direction however at different speeds. This fault line is known as the San Andreas Fault.

Ethiopia Most people in Ethiopia work in the primary sector, on farms and in mines. There are 58 million farmers in Ethiopia. Farming is important to Ethiopia because they need to grow and sell enough crops to improve their living standards (invest in education, healthcare, infrastructure). China 220 million people in China work in factories in the secondary sector. It makes more goods than any other country. China has started to develop, having recently gone through their industrial revolution (growth in manufacturing in factories). They still produce most of their own food, however the use of machines has reduced the number of workers on the farms. Due to the money they earn from manufacturing, China have developed their healthcare education and infrastructure. The UK Most people in the UK work in tertiary industries. These people provide a service in hospitals, schools, offices, banks, shops…etc. We still have some secondary industries but they need fewer workers because we use machines, robots and computers. We have very few people working in primary industries as we get most primary goods from abroad. TNC A transnational corporation is a company that operate across multiple countries. Evidence Apple is a TNC

  • Its headquarters are in California (USA). Here quaternary sector engineers program the features you love such as voice command, facial recognition…etc.
  • The materials that make up an iPhone include 60 different metals, plastic and glass. These are purchased from many countries.
  • The iPhone is created in factories mostly in China.
  • The iPhone is sold in many countries (such as USA, UK, France, Spain, Italy…etc.) KS3 Geography Knowledge: Social and Economic Development Employment The state of having work. Employment rate The % of people within a population who have jobs. The employment sectors: Primary, secondary, tertiary, quaternary Primary sector jobs Primary jobs are found…. For example… The extraction of raw materials. Raw materials are anything that is naturally present in the earth. In rural areas where the raw materials are. Farmers, fishermen, miners, oil workers, forestry workers. Secondary sector jobs Secondary jobs are found... For example…. The manufacturing of goods. Turning raw materials into higher value products often in factories. In urban areas where the factories are built. Metals become cars, crops become processed foods, cotton becomes clothes. Tertiary sector jobs Tertiary jobs are found… For example…. Tertiary sector: the provision of services for other people. In urban areas as they need a large population to sell their services to. Teachers, doctors, nurses, lawyers, policemen, dentists, bankers… Quaternary sector jobs Quaternary jobs are found.. For example…. Quaternary sector: research and information technology industries. In urban areas as they need to hire lots of highly skilled university graduates and most universities are located in cities. Scientists developing new medicines, financial planners using models to make financial decisions. Economy People produce goods and services, which other people buy. The economy means the whole network of people producing and consuming goods. Growing economy When the quantity of goods and services being produced increases. Shrinking economy When the quantity of goods and services being produced decreases. Development The process of change for the better. LIC Low Income Countries have a low income (less than $1045 per year), poor quality housing, services, healthcare…etc. Their primary source of income is from agriculture. Ethiopia, Somalia, Liberia. NEE Newly Emerging Economies are countries that have started to industrialise (move into the secondary sector – factories) and are developing. China, India, Brazil. HIC High Income Countries are developed countries that a high income (more than $12,746), good access to services and strong infrastructure. They are mainly have tertiary & quaternary industries. UK, USA, Japan, Italy, Germany. Development indicator For example… A measure of development Gross domestic product (GPD), birth rate, death rate, infant mortality rate, literacy rate, GDP The total value of the goods and services a country produces in a year Essentially it’s annual income. GDP per capita The total income divided by the total population. It gives the average salary within a country. It is important to use more than one indicator as….
  • Not all people earn the same amount of money. Therefore ….per capita is not accurate.
  • There might be an anomalous result. How has the UK’s economy changed since 1600? Economies of the world: how do economies change in different countries? 1600s Most people worked in agriculture (primary), with a few people making things in workshops (shoes, furniture) and providing services to rich families. Most of the jobs were located in rural areas. 1850s In the 1850s, less people work on farms and more people work in factories in towns and cities. This occurred due to the UK’s Industrial Revolution. This was the growth of secondary manufacturing in factories. Less people worked on farms due to the new practices (horses and ploughs). More people worked in factories due to the rapid increase in jobs available in factories. These jobs paid more too. 1970s In the 1970s, less people work in factories (secondary) and more people work in services (tertiary). Less people work in factories due to de-industrialisation – when many of the factories moved abroad to poor countries due to cheap labour. This meant many factories in the UK closed down. Also jobs in the tertiary sector pay more. Today Today most people in the UK work in services (tertiary), however the growth of computers has seen the beginning of quaternary industries in the UK. In 2018, 1% of people worked in the primary sector, 18% in the secondary sector and 81% in the tertiary sector

KS3 Geography Knowledge: Social and Economic Development Development gap The difference in development between HICs and LICs. Landlocked Countries with no coastline = difficult to trade (import/export) with other countries = difficult to make money. For example, Mali, Africa, is landlocked and has a GPD per capita of just $901. Extreme climate Many LICs have extreme climates (extreme temperatures, too much or too little rain). Extreme climate make it difficult for LICs to grow crops = lack of food to eat or sell = poverty and famine. Between 1978 and 1998, Ethiopia had 15 droughts. Natural Hazards Many LICs suffer common natural hazards ( droughts, floods, storms, earthquakes). The country is so busy responding to the natural hazard they do not have money to invest in healthcare, education, infrastructure = lack of development. For example Bangladesh suffers from annual floods which in August (2017) affected 6.9 million. Conflict & corruption Many wars occur in LICs = money is spent on the military and weapons instead on improving healthcare, education, transportation or access to services. Lack of education Lack of education = people do not have the skills to work in high paying jobs. As a result many people are unemployed or have low paying jobs = low GDP. Lack of healthcare Waterborne diseases & tropical diseases (malaria) are common in LICs due to poor sanitation (sewage gets into drinking water) and mosquitoes. A lack of healthcare stops people getting better = cannot work/die from diseases/children miss school. In 2015, 89% of all malaria cases were in sub-Saharan Africa.

CAUSES OF THE DEVELOPMENT GAP REDUCING THE GAP: AID

QUALITY OF LIFE IN AN LIC: MALAWI QUALITY OF LIFE IN AN NEE: BANGLADESH QUALITY OF LIFE IN AN HIC: SINGAPORE

Malawi is a long thin country, located in east Africa. It is about ½ the size of the UK with a population of 17 million. One of its main physical features is Lake Malawi, which is rich in fish = food and income for locals, however it is still very poor. ➢ GPD per capita = $780. ➢ Life expectancy = 55 years ➢ Literacy rate = 61% 90% of its population work in farming, exporting tobacco, sugar, tea & cotton. These are low value goods which do not make much money. It is also poor as it is landlocked making it difficult to trade with other countries. Quality of life: ➢ Poor quality clothing, lack of footwear ➢ School: class sizes of 97 children, no table and chairs, lack of equipment, students sit on the floor ➢ Home: no electricity, children sleep on mats on the mud floor. ➢ Future: education for girls is rare. Most girls get married at 18 and have babies. Bangladesh is located in southern Asia bordering India. Its population of 165 million, with 98% identifying as Bengali. It has a high a population density. Bangladesh currently is going through its Industrial Revolution = growth of factories & manufacturing. It makes the 2nd^ most clothes in the world (after China). Most clothes shops in the UK get clothing made there. This earns Bangladesh over £ billion a year and employs 4 million, helping Bangladesh to develop, improving healthcare, education & services. ➢ GPD per capita = $1698. ➢ Life expectancy = 72 years ➢ Literacy rate = 73% Quality of life in factories is not great: ➢ Low wages (£45 per month), long hours (14 hours a day, 7 days a week) ➢ Dangerous conditions: a number of factories have collapsed or caught fire. In 24 th^ April, 2013, the Rana Plaza (a factory making clothes for Primark, Matalan) collapsed killing 1100 workers. Physical & emotional abuse is also common. Singapore is an island located in south east Asia. It is very small (½ the size of Greater London). Its population is 5.5 million, with a very high population density. Singapore is one of the wealthiest countries in the world, with a large tertiary industry. Its employment structure is: 1% (primary), 16% (secondary), 83% (tertiary). Unfortunately, 15% of the population are poor: the wealth is not evenly distributed. It earns money by importing cheap raw materials from LICs and turning these into more expensive products in factories. These are exported (sold) = profit. Its main source of income, however, is from its tertiary industries ( finance, insurance ). ➢ GPD per capita = $57,700. ➢ Life expectancy = 84 years ➢ Literacy rate = 97% Quality of life: ➢ Home: smart clothes, lots of delicious food, many families have a maid. ➢ Great education – extracurricular activities and lots of facilities ( swimming pools, gym, basketball court ) Aid Another word for help. Richer countries^ give poorer countries aid to help them make a better future for themselves. Bilateral aid Aid given from one government to another (the UK gives aid to Pakistan). Multilateral aid Aid given through an international organisation (the World Bank, the UN) NGOs Non-Governmental Organisations are charities (e.g. Oxfam, WaterAid). The DfID is… The Department for International Development is responsible for the UK’s bilateral aid. How does the UK provide aid? In 2018, the UK invested £14.5 billion in aid projects, such as for disaster relief, education, healthcare, access to services. To countries such as Ethiopia, Pakistan, Somalia and Nigeria. Sustainable aid…

  • Helps those that need it the most and helps in the long term.
  • Involves the locals and teaches people skills. Is cheap, using appropriate technology that can be easily maintained by locals. Large scale aid projects. Large scale projects are expensive and well-publicised schemes producing help to large areas. To help Ghana develop the Akosombo Dam was built on the River Volta. It was to built to generate hydro-electricity, which is clean renewable energy formed by fast flowing water. ✓ The dam produces clean renewable energy for locals to use and Ghana to sell = more money for healthcare, education, services ✓ The lake behind the dam gives water for irrigation = more crops to eat and sell. × Money was borrowed from USA on the condition that an American company Valco could use electricity from the dam at a very cheap price = there is often little left for the locals = blackouts. × It cost £130 million and took 8 years to make. Also 80,000 people were forced to move due to flooding caused by the lake behind the dam. Small scale aid projects Small scale projects are government or charity funded. The provide specific improvements for a small area and prioritise training of locals so that they can become self-sufficient. To help Ghana to develop, WaterAid built water pumps in remote villages. ✓ It was cheap (£1200 per water pump) and used appropriate technology locals could use. ✓ It involved the locals to decide where to build the pumps and trained locals how to use and fix it. ✓ Clean water = children can go to school, families have clean water to cook, drink and clean, there are less waterborne diseases. × It is small scale so fewer people were helped.

KS3 Geography Knowledge: Weather and Climate EFFECTS OF THE TEWKESBURY FLOOD A river flood is when a river overflows its banks and water spreads across the surrounding land. It is caused due to heavy precipitation. Tewkesbury, a market town in Gloucestershire (south west England), was badly affected by a flood in 2007. Following a very dry April, the summer of 2007 was one of the wettest on record. By the end of June, heavy rainfall overloaded rivers, leading to flooding in some areas in Gloucestershire. However, during July the rains were even heavier. On 20th July, two months' worth of rain fell in 14 hours. This resulted in widespread devastation.

EFFECTS OF THE MILLENNIUM DROUGHT

Between 2002 and 2009 south-east Australia experienced its worst drought in 125 years. This was known as the Millennium Drought. The dry and hot conditions resulted in desertification. This is when land becomes ‘desert like’ and too dry to grow crops on. CLIMATE GRAPHS

  • Weather is the state of the atmosphere at a given time. The photo shows warm, dry weather in Plymouth, however it might have been raining an hour later.
  • Climate is the average weather in a place – what the weather is usually like. To work it out you collect data over a long period & then calculate average measurements for each month. Geographers collect climate data to use this to calculate average weather conditions each month (e.g. temperature and precipitation). This data is plotted on a climate graph. A climate graph shows how precipitation and temperature change throughout the year.

EXPLAINING GLOBAL CLIMATES

Social impacts

  • 2 people died
  • 5000 homes and businesses were flooded = 825 homes were evacuated.
  • 48 homes were without electricity for 2 days.
  • 135,000homes were without drinking water for 2 weeks
  • Transport lines were destroyed. Economic impacts
  • Cost: £50 million
  • Destruction to transport lines cost £25 million
  • 5000 homes and businesses were flooded and 7500 businesses were without mains water for 17 days = businesses temporarily closed down = unemployment and lack of earnings. Environmental impacts
  • Floodwater destroyed crops and contaminated groundwater.
  • Habitats were lost. Social impacts
  • Families had to sell their farms due to loss of crops & livestock.
  • The rate of suicides among farmers increased.
  • Buildings started to crack due to extreme temperatures forcing people to evacuate.
  • The government imposed hosepipe bans and limited showers to just four minutes.
  • Water and food bills increased by 20%. Economic impacts
  • 40% of the land became desertified = crop yields dropped by 66%.
  • The lack of food being produced in Australia = they stopped making money from exporting foods and have to spend more money importing food from other countries.
  • The government spent millions on helping farmers cope with the effects of the drought.
  • The tourism industry declined as people went to other countries. Environmental impacts
  • 40% of the land became desertified. The dry conditions led to dry soils that were vulnerable to soil erosion.
  • Many livestock (animals) died due to a lack of water and food.
  • Many habitats were lost due to wildfires and lack of water = a dramatic loss in biodiversity as animal and plant species died. Altitude The higher you are above sea level, the colder it is. The temperature falls by about 1°C every 100 meters. Many areas in the Alps (a mountain range in Europe) are 40°C colder than the coastal areas because they are 4000m high. This also explains why you can find snow on Mt Kilimanjaro which lies on the equator. Prevailing Wind Prevailing wind is the most common wind direction.
  • If the prevailing wind direction is over water (sea/ocean), it brings rain.
  • If the prevailing wind direction is over land, it brings dry air. In the UK, the prevailing wind is from the SW, over the Atlantic Ocean = moist (wet) air which is why we have lots of rain. Ocean Currents The temperature of water surrounding a country affects its temperature.
  • If there are warm ocean currents, the temperature will be warm.
  • If there are cold ocean currents, the temperature will be cold. In Britain we have warm ocean currents, which have travelled across the Atlantic Ocean from the Gulf of Mexico where it is hot. This ocean current is called the North Atlantic Drift and it warms the coast of the UK. Latitude Latitude means how far a place is from the equator.
  • Far from the equator (e.g. poles) it is very cold. This is because the earth is curved = many of the sun’s rays bounce off the earth’s surface. Therefore there is indirect sunlight which shines at a low angle onto a larger area.
  • At the equator it is very hot. This is because there is direct sunlight which shines directly onto a small area = hot.

KS3 Geography Knowledge: Rivers River A channel of water which flows downstream. Social uses of the river ▪ Supplying water to people’s homes: Water is taken from the Thames, cleaned and piped to millions of homes. Dirty water is collected from homes, cleaned and put back in rivers. ▪ Leisure activities: Rowing, canoeing, swimming, picnics, walking. Over 250,000 fishing licenses are brought each year to fish along the Thames and its tributaries. ▪ Transporting people : The Thames River Boats transport thousands of people to work everyday. Tourists also enjoy Thames cruises. Economic uses of the river ▪ Use in industries: Factories (e.g. the Ford Factory in east London) uses water for cooling and washing factory machinery. ▪ Transporting goods to other countries: London Gateway Port is located in East London. It is used for importing and exporting goods. ▪ Producing electricity to sell. In power stations, steam drives turbines. River water is used to cool tanks of steam. For example in the power station beside the Thames at Didcot. ▪ Agriculture (farming) A lot of the River Thames passes through rural areas and farmland. Farmers use the river water to water their crops in dry weather (irrigation). Erosion The wearing away or breakdown of rocks by wind, water or ice. Hydraulic Action The force of water hits against the river channel and removes material. It is common with fast moving, high energy water. Abrasion Sediment carried by the river hits the river channel and removes material. Corrosion Chemicals in the water dissolve rocks (e.g. limestone) Attrition Stones carried by the river hit into each other, gradually making the rocks smaller and smoother. Rocks in the upper course are large and more angular than rocks in the lower course. Transportation Eroded material is carried by the river downstream. Traction Large particles roll along the river bed. Saltation Pebble-sized particles bounce along the river bed. Suspension Small particles (silt and clay) are carried in the water. Solution Soluble materials dissolve in the water and are carried along. Deposition Deposition takes place where a river does not have enough energy to carry sediment (its load). As a result it is dropped. WATERFALL A waterfall is a steep fall of water, where water flows over a ledge of hard rock.

  1. Waterfalls occur in areas where hard rock overlies soft rock.
  2. The soft rock erodes more quickly than the hard rock, creating a plunge pool and overhanging ledge.
  3. Further erosion of the soft rock, makes the plunge pool deeper and the overhanging ledge unstable. Eventually the ledge falls into the plunge pool.
  4. As the steps 1-3 are repeated, the waterfall retreats upstream. GORGE A gorge is a narrow, steep sided valley that is found immediately downstream from a waterfall. It is formed by the gradual retreat of a waterfall over hundreds or thousands of years.

LANDFORMS FORMED BY EROSION

LANDFORMS FORMED BY EROSION and DEPOSITION MEANDER A bend in the river.

  1. It starts with a slight bend.
  2. Water moves faster on the outside of the bend and slower on the inside.
  3. The fast water erodes the outside of the bend. The slower water deposits material on the inside of the bend.
  4. Continued erosion and deposition makes the bend bigger. OX-BOW LAKE U-shaped lakes formed when a meander is no longer connected to a river
  5. Further erosion and deposition make the meander bend larger and the neck of the meander (A) narrows.
  6. Eventually the neck breaks through and the water takes the most direct route, avoiding the meander.
  7. As less water is flowing through the meander, the energy is reduced = deposition. The meander is blocked off and an oxbow lake is created.
