The 20 questions

  1. What two trends drive increased resource use and waste production?

    • migration and birth rate
    • population and living standards
    • photosynthesis and respiration
    • temperature and rainfall

  2. What is caused if waste and chemical materials are not properly handled?

    • more biodiversity
    • higher air pressure
    • more pollution
    • increased respiration

  3. Which of these is a source of water pollution named in the specification?

    • acidic gases
    • smoke
    • landfill
    • sewage

  4. Which examples of air pollution are stated in the specification?

    • smoke and acidic gases
    • landfill and plastic
    • toxic chemicals and oil
    • sewage and fertiliser

  5. Which examples of land pollution are stated in the specification?

    • landfill and toxic chemicals
    • smoke and sewage
    • smoke and acidic gases
    • sewage and fertiliser

  6. What direct effect does pollution have on plants and animals?

    • it speeds evolution
    • it increases growth
    • it kills them
    • it improves habitats

  7. Which is an example of water pollution in the specification?

    • landfill
    • fertiliser
    • smoke
    • acidic gases

  8. Which land use type specifically contributes to land pollution and waste accumulation?

    • landfill
    • nature reserves
    • crop farming
    • peat bogs

  9. Fertiliser from a farm runs off into a river and fish die. What type of pollution is this?

    • air pollution
    • noise pollution
    • water pollution
    • land pollution only

  10. A factory releases acidic gases that damage trees. Which type of pollution is this?

    • land pollution
    • air pollution
    • water pollution
    • no pollution

  11. Toxic chemicals are buried in a landfill site. Which type of pollution is this?

    • air pollution
    • light pollution
    • land pollution
    • water pollution only

  12. In which three media can environmental pollution occur?

    • rivers, lakes and oceans
    • atmosphere, crust and mantle
    • soil, rocks and ice
    • water, air and land

  13. What is the primary effect of handling waste properly?

    • stops population growth
    • increases biodiversity
    • creates more energy
    • reduces pollution

  14. Which of these is a source of water pollution listed in the specification?

    • smoke
    • acidic gases
    • sewage
    • landfill

  15. Which factor combined with rapid population growth increases waste?

    • rising living standards
    • decreased energy use
    • reduced deforestation
    • falling temperature

  16. What ecological measure is reduced when pollution kills plants and animals?

    • ambient temperature
    • salinity levels
    • biodiversity
    • air pressure

  17. Air pollution links waste management content to which chemistry topic?

    • periodic trends
    • organic reactions
    • atmospheric pollutants
    • energy changes

  18. Which water pollutant is explicitly named alongside sewage and toxic chemicals?

    • landfill
    • fertiliser
    • acidic gases
    • smoke

  19. What is the consequence of rising living standards on resource consumption?

    • fewer resources used
    • resources regenerate faster
    • resource use stops
    • more resources used

  20. What effect do toxic chemicals in water have on ecosystems?

    • reduces biodiversity
    • increases biomass
    • boosts plant growth
    • enhances speciation
