- A factor that increases risk because densely populated cities concentrate people and infrastructure, amplifying exposure to earthquakes.AQA, Pearson Edexcel
V
- Vegetation structure
- The vegetation is highly stratified into distinct layers: the emergent layer, canopy, under canopy, and shrub layer.AQA
- Vertical erosion
- Erosion that dominates in the upper course, where the channel is narrow and shallow within a steep V-shaped valley.AQA, Pearson Edexcel
- Virtual Water
- The volume of fresh water used to produce a product, measured at the place where the product was actually produced.Pearson Edexcel
- Visual intrusion
- When a man-made structure negatively impacts the natural beauty of a landscape.Pearson Edexcel
- Visual methods
- Methods such as annotated field sketches and photographs that capture qualitative observations like coastal erosion features.AQA
- Visual sources
- Sources such as photographs, satellite images and sketches that offer qualitative insights into landscapes and environmental changes.AQA
- Volcanic cooling
- Volcanic activity ejects ash and sulfur dioxide into the stratosphere, and these aerosols reflect incoming solar radiation back into space, causing a…AQA
- Volcanism
- Volcanic eruptions, which are primarily found at constructive and destructive margins where magma reaches the surface.AQA
- Vulnerability
- The susceptibility of a population to the damaging effects of a hazard.Pearson Edexcel
- Vulnerability and poverty
- Lacking the financial means to relocate, which traps many people in high-risk areas.AQA
- Vulnerability and risk
- The severity of risk depends on the vulnerability and capacity of the population to cope.AQA
W
- Waste disposal
- A major environmental issue as urban populations grow, requiring sustainable solutions like recycling and energy recovery rather than relying on unsustainable…AQA
- Waste management
- Effective management that is vital as urban populations grow and waste generation increases, reducing the volume of waste sent to landfill sites.AQA
- Waste recycling
- Processing used materials into new products, such as separating paper, glass, plastics and metals at the household level for kerbside collection.AQA
- Water and soil management
- Techniques such as building stone lines (bunds) along contours, which trap water and prevent topsoil from washing away.AQA
- Water conservation
- Reducing demand and managing supply efficiently, for example through dual-flush toilets, rainwater harvesting for gardens and water meters to encourage…AQA
- Water deficit
- A condition where rainfall is suppressed by high-pressure systems or demand outpaces supply, typically around 30 degrees north and south of the equator.AQA, Pearson Edexcel
- Water insecurity
- A situation in which demand exceeds supply, so clean water is scarce and people often rely on polluted sources.AQA, Pearson Edexcel
- Water recycling
- Treating wastewater so it can be reused for industrial processes or agriculture, reducing the demand for fresh water.AQA
- Water Scarcity
- A severe lack of water, defined as annual supplies dropping below 1,000m³ per person per year.Pearson Edexcel
- Water security
- Having a reliable, accessible, and affordable supply of clean water to meet the needs of a population and economy.AQA
- Water Stress
- The demand for water exceeding the available amount during a certain period, which can be caused by over-extraction as well as low rainfall.AQA, Pearson Edexcel
- Water supply
- A critical challenge because low and unreliable rainfall means water must be carefully managed, often requiring expensive infrastructure like pipelines or…AQA
- Water surplus
- A condition where precipitation exceeds evaporation, generally found near the equator and in high latitudes.AQA, Pearson Edexcel
- Water transfer
- Moving water through canals or pipes from regions with a water surplus to those with a water deficit.AQA
- Water Transfer Scheme
- Large-scale engineering projects that move water from areas of surplus to areas of deficit via pipes and canals.Pearson Edexcel
- Water treatment
- The use of filtration and chemical purification in plants to ensure water is safe for consumption.AQA
- Wave energy
- Reduced in sheltered areas such as bays by headlands, and by friction with the seabed in shallow water.AQA
- Wave formation
- Waves are generated by wind blowing over the sea surface, and their size depends on wind speed, duration and fetch.AQA
- Wave-cut notch
- A notch formed at the base of a cliff by wave action undercutting it, eventually leading to cliff collapse.AQA
- Wave-cut platform
- A rocky, gently sloping platform left behind by the continuous retreat of a cliff, typically exposed at low tide.AQA
- Wealth inequality
- Averages like GNI per head mask extreme wealth inequalities within a population, as a country might have a high GNI due to a few extremely wealthy individuals…AQA
- Weather hazards
- Tropical storms, known regionally as hurricanes, cyclones and typhoons, are intense low-pressure systems developing over warm oceans above 27°C.AQA
- Weathering
- The breakdown of rock in situ, in its original place, by the action of the weather, plants, and animals.AQA, Pearson Edexcel
- Weathering processes
- Break down exposed rock above the glacier, particularly through freeze-thaw action, which provides the angular rock fragments enabling erosion.AQA
- Wind patterns
- Surface winds blow from high-pressure areas towards low-pressure zones to balance the atmosphere, and the Earth's rotation deflects these winds due to the…AQA
- Wind Shear
- A change in wind speed or direction with altitude.Pearson Edexcel
X
- Xerophyte
- A plant adapted to survive in an environment with very little liquid water, such as a desert.Pearson Edexcel
Other terms
- 'Grey' water
- Gently used water from sinks, showers, and washing machines (excluding toilet waste) that is collected and reused for purposes like flushing toilets or…AQA
- 90th percentile
- Means 90% of the data falls below this value.AQA
