Natural Hazard Risks

• Natural hazard: A natural event or process — such as an earthquake, volcanic eruption, tropical storm, flood, or drought — that has the potential to cause harm to people or damage to property.
• Vulnerability: The degree to which people and places are susceptible to harm from a natural hazard. High vulnerability means greater potential for loss of life, injury, and damage to property.

Understanding Tectonic Hazards

• Convection current: The circular movement of mantle material driven by heat from the Earth's core. Hot rock rises, spreads, cools, and sinks — this cycle is the driving force behind tectonic plate movement.
• Focus: The point underground where an earthquake originates — where the rock first fractures and energy is released. Shallow-focus earthquakes (less than 70 km deep) tend to cause more surface damage than deep-focus ones.
• Hot spot: A fixed area of intense heat in the mantle, not located at a plate boundary, where magma burns through the overlying crust to form a volcano. The Hawaiian Islands formed over a mantle hot spot as the Pacific Plate moved slowly over it.

Impacts and Management of Tectonic Hazards

• Primary effect: An immediate, direct consequence of the tectonic event itself. Examples include ground shaking causing building collapse, lava flows destroying farmland, or a tsunami inundating a coastline.
• Secondary effect: A consequence that arises as a result of primary effects, developing over hours to weeks after the event. Examples include disease outbreaks, economic disruption, and displacement of populations.

Understanding Weather Hazards

• Coriolis Effect: The deflection of moving air (and water) caused by the Earth's rotation. It causes tropical storms to spin and is essential for their formation. It is absent at the equator, which is why storms do not form there.

Weather Hazards in the UK

• Jet stream: A fast-moving ribbon of air high in the atmosphere that steers weather systems across the UK. When it shifts north or south, it changes which air masses reach Britain and how long they stay.
• Surface water flooding: Flooding caused when rainfall intensity exceeds the capacity of drains and the ground to absorb water. Common in urban areas where impermeable surfaces prevent infiltration.

What's Causing Climate Change?

• Orbital changes (Milankovitch cycles): Slow, predictable variations in three aspects of Earth's movement around the Sun — the shape (eccentricity) of its orbit, the tilt of its axis (obliquity), and the wobble of its axis (precession). Together these alter how much solar energy reaches Earth and where, triggering ice ages and warmer interglacial periods over cycles of tens of thousands of years.
• Enhanced greenhouse effect: The intensification of the natural greenhouse effect caused by rising concentrations of greenhouse gases — primarily CO2 and CH4 — from human activity. More infrared radiation is trapped in the lower atmosphere, raising global average temperatures above what natural factors alone would produce.

Managing Climate Change: Mitigation and Adaptation

• Mitigation: Actions that reduce the causes of climate change, primarily by cutting greenhouse gas emissions or removing carbon dioxide from the atmosphere. Think of mitigation as turning down the heat on the hob before the pot boils over.
• Adaptation: Actions that adjust human systems and environments to cope with the effects of climate change that are already occurring or are unavoidable. Adaptation accepts that some warming is inevitable and focuses on reducing harm.

Ecosystems: Scales & Interactions

• Ecosystem: A system in which living organisms (biotic components) interact with each other and with non-living environmental factors (abiotic components) in a specific area. Ecosystems can exist at any scale, from a small rock pool to a vast tropical rainforest.
• Biotic component: Any living organism within an ecosystem. Examples include oak trees, earthworms, foxes, bacteria in the soil, and algae in a pond. Biotic components affect each other through food chains, competition, and nutrient cycling.

Tropical Rainforest Characteristics & Deforestation Causes

• Convectional rainfall: Rainfall produced when intense surface heating causes moist air to rise rapidly, cool, and condense. Common in equatorial regions and responsible for the heavy afternoon downpours characteristic of tropical rainforests.

Impacts of Deforestation

• Soil erosion: The removal of the topsoil layer by wind or water. In deforested areas, rain hits bare ground directly, dislodging soil particles and washing them into rivers. Without tree roots to anchor the soil, erosion accelerates rapidly.
• Greenhouse effect (enhanced): The process by which greenhouse gases such as carbon dioxide trap heat in the Earth's atmosphere. Deforestation enhances this effect by increasing atmospheric CO2 levels, leading to rising global temperatures.

Sustainable Management of Tropical Rainforests

• Deforestation: The permanent removal of trees from a forested area, often to clear land for farming, logging, or development. It leads to biodiversity loss, soil erosion, increased carbon dioxide emissions, and disruption to the water cycle.
• Ecotourism: A form of tourism focused on natural environments that generates income for local communities while minimising environmental damage. It gives the forest an economic value without destroying it.

Hot Desert Development: Opportunities & Challenges

• Extreme temperatures: In hot deserts, daytime temperatures regularly exceed 40°C and can reach 50°C or above. At night, temperatures can drop below 0°C because the dry air and lack of cloud cover allow heat to escape rapidly. This daily temperature range — sometimes over 40°C in a single day — damages machinery, degrades building materials, and creates serious health risks for workers.
• Water supply: Hot deserts receive less than 250 mm of rainfall per year — some receive almost none. Surface water is virtually absent, meaning all water for drinking, construction, and agriculture must come from deep aquifers, distant rivers, or expensive desalination plants that convert seawater into fresh water.

Hot Desert Ecosystems & Desertification

• Arid: Describes a climate or region with very low rainfall (below 250 mm per year) and high evaporation rates, resulting in a net water deficit. Hot deserts are classified as arid environments.

Distinctive Characteristics of Cold Environments

• Albedo: The proportion of incoming solar radiation reflected by a surface. Ice and snow have a high albedo (reflecting up to 90% of sunlight), which keeps polar regions cold. Dark ocean water has a low albedo and absorbs more heat.
• Thermokarst: The uneven, subsiding ground that forms when permafrost thaws, either naturally or due to human activity. It creates boggy hollows, collapsed slopes, and unstable foundations, making construction and infrastructure maintenance extremely difficult.

Development in Cold Environments: Opportunities & Challenges

• Mineral Extraction: The removal of valuable minerals from the ground, including oil, natural gas, coal, gold, diamonds, and iron ore. Cold environments hold some of the world's largest untapped reserves of these resources.
• Energy Development: The generation of power from resources found in cold environments, including oil, natural gas, and increasingly renewable sources such as hydroelectric power from glacial meltwater rivers.
• Extreme Temperature: Temperatures in cold environments regularly fall below -30°C in winter, with wind chill making conditions feel far colder. This affects machinery, human health, construction materials, and the ability to work outdoors.

Diverse UK Landscapes

• Geology: The type, age, and arrangement of rocks beneath the land surface. Geology is the single most important control on what kind of landscape develops in any given area of the UK.
• Permeable rock: Rock that allows water to pass through it, either through pores (porous) or cracks (pervious). Chalk is a key example in the UK. Permeable rocks produce dry valleys and few surface streams.

Coastal Processes: Weathering, Erosion & Transportation

• Mechanical weathering (freeze-thaw): Water enters cracks in rock, freezes, expands by roughly 9%, and widens the crack. Repeated freeze-thaw cycles eventually break fragments away from the cliff face. This is most active where temperatures regularly cross 0°C.
• Chemical weathering (carbonation): Rainwater absorbs carbon dioxide from the atmosphere to form a weak carbonic acid. This acid reacts with calcium carbonate in rocks such as limestone and chalk, slowly dissolving the rock surface over time.
• Hydraulic power (hydraulic action): The force of waves crashing against a cliff face. Air becomes trapped in cracks and is compressed by the wave; when the wave retreats, the pressure is suddenly released, causing the crack to widen. Repeated compression and decompression eventually shatters the rock.
• Abrasion (corrasion): The sandpaper effect: waves pick up sand, pebbles, and boulders and hurl them against the cliff face, grinding and scraping the rock away. This is the most powerful erosional process at most coastlines.
• Attrition: The process by which sediment particles collide with each other as they are transported by waves, gradually becoming smaller, rounder, and smoother over time. Attrition does not erode the cliff — it reduces the size of the sediment already in transport.

Deposition and Coastal Landforms

• Deposition: The laying down of sediment that has been transported by waves, longshore drift, or other coastal processes. It occurs when wave energy decreases — for example, in sheltered bays or where the coastline changes direction.
• Spit: A narrow ridge of sand or shingle that extends from the land into the sea or across a river mouth. It forms where longshore drift continues past a bend in the coastline, depositing sediment in open water. The end of a spit often curves due to secondary wind directions.
• Discordant coastline: A coastline where bands of alternating hard and soft rock run perpendicular (at right angles) to the sea. Soft rock erodes faster to form bays, while hard rock remains as headlands. This produces an irregular, indented coastline.

Coastal Management: Hard, Soft, and Retreat

• Sea wall: A concrete or rock barrier built at the base of a cliff or at the top of a beach to reflect wave energy back out to sea. Sea walls are one of the most expensive hard engineering options but provide strong protection for settlements directly behind them.
• Rock armour (rip rap): Large boulders, often imported from Norway or Scotland, piled at the base of a cliff or sea wall to absorb and dissipate wave energy. Cheaper than a sea wall but less visually appealing and can disrupt beach access.
• Gabions: Wire mesh cages filled with small rocks or pebbles, stacked to form a wall or revetment. Gabions are cheaper than sea walls, allow some water drainage through the structure, and can be built quickly, though they have a shorter lifespan.
• Groynes: Wooden, rock, or concrete structures built perpendicular to the shoreline to interrupt longshore drift and trap sediment, building up the beach. A wider beach acts as a natural buffer, absorbing wave energy before it reaches the cliff or sea wall.
• Beach nourishment: The process of adding large quantities of sand or shingle to a beach that has been depleted by erosion or longshore drift. The wider, higher beach absorbs more wave energy and protects the land behind it.
• Beach reprofiling: The reshaping of a beach's cross-section, typically by moving sediment from the lower beach back to the upper beach after storm events. This restores the beach's natural profile and its ability to absorb wave energy.
• Dune regeneration: The restoration and stabilisation of sand dunes by planting marram grass, installing fencing to trap windblown sand, and restricting public access to allow dunes to re-establish. Dunes act as a natural buffer against storm waves and coastal flooding.

River Processes: Erosion, Transportation, and Deposition

• Hydraulic action: The sheer force of moving water is driven into cracks in the river bed and banks. Air trapped inside those cracks is compressed, then released as the water retreats. This repeated compression and expansion weakens the rock until fragments break away.
• Abrasion: Sediment carried by the river — sand, gravel, and boulders — is dragged and scraped along the bed and banks, grinding them down like sandpaper. Also called corrasion.
• Solution (erosion): Soluble minerals in the rock — particularly calcium carbonate in limestone — are dissolved directly by slightly acidic river water and carried away in solution. No visible sediment is produced. This is the fourth process of river erosion, alongside hydraulic action, abrasion, and attrition.

Managing Rivers: Hard and Soft Engineering

• Dams and reservoirs: A dam is a large barrier built across a river valley to hold back water, creating an artificial lake called a reservoir. Water is released in a controlled way, preventing sudden surges downstream that would cause flooding.
• Channel straightening: Artificially straightening a river's course by cutting through meanders, so water moves through the channel faster and clears the area more quickly during a flood event.
• Embankments (levees): Raised banks of earth or concrete built along the sides of a river channel to increase its capacity, allowing it to hold more water before it overflows onto the floodplain.
• Flood relief channels: Artificial channels built alongside a river that carry excess water away during a flood, diverting it around a settlement and rejoining the main river further downstream.
• Flood warnings and preparation: Systems that monitor river levels and rainfall, issuing advance warnings to communities so people can protect property and evacuate if necessary before a flood arrives.
• Floodplain zoning: A planning strategy that divides the floodplain into zones based on flood risk, restricting or prohibiting certain types of development in high-risk areas to reduce potential flood damage.
• Planting trees (afforestation): Planting trees in a river's catchment area to intercept rainfall, increase infiltration into the soil, and slow the movement of water into the river, reducing peak discharge and flood risk.
• River restoration: Returning a river to a more natural, meandering course after it has been artificially straightened, allowing it to slow down, store more water, and function as a natural flood buffer.

River Management: A Case Study

• Flood embankment (levee): A raised bank of earth or concrete constructed along a river channel to contain floodwater within the channel and prevent it spreading onto the floodplain. A hard engineering technique.

Glacial Processes: Weathering, Erosion & Transportation

• Freeze-thaw weathering: A mechanical weathering process in which water enters a crack or joint in rock, freezes and expands, exerting pressure on the surrounding rock. Repeated cycles of freezing and thawing progressively widen the crack until fragments of rock break off. Also called frost shattering.
• Plucking: An erosional process in which meltwater at the base of a glacier seeps into joints and cracks in the bedrock, refreezes around the rock, and bonds it to the glacier. As the glacier moves forward, it pulls — or plucks — these blocks of rock away from the bedrock.
• Rotational slip: The curved, rotational movement of ice within a bowl-shaped hollow (corrie). Ice moves in a scooping arc, deepening the hollow through erosion and transporting eroded material downslope.
• Bulldozing: A transportation process in which the advancing snout of a glacier pushes loose sediment, soil, and rock debris ahead of it across the landscape, depositing it as a ridge when the glacier retreats.

Glacial Deposition and Landforms

• Drumlin: An elongated hill of till deposited and shaped beneath a moving glacier. The blunt, steep end (stoss) faces the direction the ice came from; the tapered, gentle end (lee) points in the direction the ice was travelling.

Tourism in Glacial Upland Areas: Impacts & Management

• Social impact: The effect of tourism on the people who live in or visit an area — including quality of life, community cohesion, and access to services.
• Traffic management: Strategies to reduce the number of private vehicles entering a sensitive area, such as park-and-ride schemes, road closures, and charging for car parks. Used to cut congestion, air pollution and road damage in National Parks.

Food and Energy Demands

• High-value food exports: Perishable or premium food products — such as fresh fruit, vegetables, cut flowers, and seafood — grown in low-income countries (LICs) and exported to wealthier markets. Examples include green beans from Kenya and asparagus from Peru.
• Fossil fuels: Non-renewable energy sources formed from the remains of ancient organisms over millions of years. The three main fossil fuels are coal, oil, and natural gas. Burning them releases CO2, contributing to climate change.
• Renewable energy: Energy from sources that are naturally replenished and will not run out on a human timescale. Examples include wind, solar, hydroelectric, tidal, and geothermal power. Unlike fossil fuels, they produce little or no direct CO2 during operation.

Water Management and UK Resources

• Water pollution: The contamination of water bodies — rivers, lakes, groundwater, or reservoirs — by harmful substances that degrade water quality and threaten human health or ecosystems.
• Rain shadow effect: The reduction in rainfall on the leeward (sheltered) side of a mountain range. As moist air rises over uplands it cools and deposits rain; descending on the other side, it warms and holds moisture, leaving eastern areas drier.
• Water transfer scheme: A system of pipelines, aqueducts, tunnels, or river diversions that moves water from areas of surplus to areas of deficit. Designed to balance regional supply and demand.

Global Food Patterns & Consumption

• Calorie surplus vs. calorie deficit: A calorie surplus exists where average intake exceeds nutritional requirements — common in high-income countries. A calorie deficit exists where average intake falls below requirements — concentrated in low-income countries, particularly in sub-Saharan Africa and parts of South Asia.
• Dietary transition: The shift in food consumption patterns that typically accompanies economic development — from simple, plant-based staple diets towards more varied diets including greater quantities of meat, dairy, and processed foods. This transition increases the total resources required to feed each person.

Strategies for increasing food supply.

• Irrigation: The controlled supply of water to farmland through channels, pipes, or sprinkler systems, allowing crops to grow in areas with low or unreliable rainfall.

Sustainable Food & Local Schemes

• Sustainable food supply: Food production that meets current needs without compromising the ability of future generations to meet their own needs. It balances environmental protection, economic viability, and social equity.

Global Water Patterns & Consumption

• Economic development and water demand: As countries industrialise and living standards rise, water consumption increases across three sectors: industry (manufacturing, energy production), agriculture (irrigation for larger food supplies), and domestic use (more appliances, higher personal consumption). Wealthier populations use significantly more water per person than poorer ones.
• Water insecurity: A situation where a population cannot reliably access sufficient safe water to meet basic needs. It can result from physical scarcity, poor infrastructure, pollution, or poverty — and can drive migration, conflict, and food insecurity.

Sustainable Water Management

• Water conservation: Reducing the volume of water used through behavioural change, technology, or pricing. Examples include low-flow showerheads, metered water bills, drought-resistant crops, and drip irrigation in agriculture.
• Groundwater management: The controlled extraction of water from underground aquifers, combined with measures to prevent over-abstraction, pollution, and long-term depletion of these stores.
• Water recycling: The treatment of wastewater (from sewage, industry, or stormwater) to a standard where it can be safely reused, either for drinking water (indirect potable reuse) or for industrial and agricultural purposes.
• Grey water: Relatively clean wastewater generated from domestic sources such as baths, showers, and washing machines — but not from toilets. Grey water can be collected and reused for toilet flushing, garden irrigation, or car washing without full treatment.

Global Energy Landscape

• Economic development: The process by which a country's economy grows, typically involving industrialisation, urbanisation, and rising incomes. As countries develop, energy demand rises because factories, transport networks, and households all require more power.

Energy Sources: Renewable vs. Non-Renewable

• Renewable energy sources: Sources replenished naturally on a human timescale, meaning they will not be exhausted by use. AQA requires you to know: biomass, wind, hydro, tidal, geothermal, wave, and solar.
• Non-renewable energy sources: Sources that took millions of years to form and cannot be replaced once consumed. AQA requires you to know: fossil fuels (coal, oil, natural gas) and nuclear power.

Sustainable Energy Solutions

• Local renewable energy scheme: A small- to medium-scale project that generates energy from renewable sources (such as solar, wind, or micro-hydro) to serve a specific community or region, rather than feeding into a national grid. Particularly valuable in rural LIC and NEE settings where grid connection is costly or unavailable.

Geographical applications

10 cards from 6 lessons. Each term links to the lesson it comes from.

Understanding Issue Evaluation

• Synoptic thinking: Drawing on knowledge from more than one geographical theme to analyse an issue. In Issue Evaluation, this means linking physical processes (such as flooding or climate) with human factors (such as urban growth or economic development) to build a complete argument.
• Justified decision: A response that selects one option, supports that choice with geographical evidence from the sources and your own knowledge, acknowledges the limitations or trade-offs of that option, and reaches a clear overall conclusion.

Using the Resource Booklet

• Interest group: A group of people with a shared stake in a geographical issue, whose viewpoint is shaped by how the issue affects them. Examples include local residents, environmental campaigners, businesses, and government bodies.

Developing a Critical Perspective

• Critical perspective: A reasoned, evidence-based judgement on a geographical issue that weighs up competing viewpoints, advantages, disadvantages, and alternatives before reaching a conclusion.
• Evaluation ladder (AQA GCSE Geography): Level 1 responses describe features or list points. Level 2 responses explain causes or effects with some development. Level 3 responses evaluate with balanced judgement, specific evidence, and a supported conclusion.

Fieldwork Enquiry: Question to Data Collection

• Hypothesis: A specific, testable prediction about what you expect to find. Often written as a statement rather than a question, for example: 'Pedestrian footfall decreases with distance from the town centre.' A good hypothesis links two measurable variables.
• Sampling strategy: The approach used to decide which locations, people, or time periods to collect data from. The three main types are: random (locations chosen by chance, removing bias), systematic (locations chosen at regular intervals, ensuring even coverage), and stratified (locations chosen to reflect the proportions of different groups or zones in the study area).

Presenting and Analysing Fieldwork Data

• Quantitative data: Numerical data that can be measured and counted, such as pedestrian counts, river depth in centimetres, or noise levels in decibels. Best displayed using graphs, charts, or scatter plots.
• Sampling method: The strategy used to decide where, when, and from whom data is collected. Random sampling removes bias; systematic sampling ensures even spatial coverage; stratified sampling ensures subgroups are proportionally represented.

Conclusions and Evaluation in Fieldwork

• Enquiry question: The specific geographical question that drives the fieldwork investigation. Every conclusion must refer back to this question directly, using evidence from the data collected.
