  4. What is a slow-moving mass of ice on land that grows or shrinks?

    • Glacier
    • Iceberg
    • Ice shelf
    • Sea ice

  5. On a standard line graph of climate data, which axis shows the year?

    • Side axis
    • Vertical axis
    • Y-axis
    • Horizontal axis

  6. Which instrument is most often used to record changes in air temperature over time?

    • Rain gauge
    • Thermometer
    • Anemometer
    • Barometer

  7. What is the main evidence used by scientists to show rising global temperatures since 1900?

    • Tree rings
    • Ice cores
    • Sediment layers
    • Weather stations

  8. What do scientists call the difference between a measured temperature and a long-term average?

    • Temperature range
    • Temperature anomaly
    • Temperature drift
    • Temperature peak

  9. Roughly how much has the world's average temperature risen since 1900?

    • About 0.2 Celsius
    • About 0.8 Celsius
    • About 1.2 Celsius
    • About 2.0 Celsius

  10. Which major part of the Earth system has shown a rapid fall in summer ice since 1980?

    • Arctic Ocean
    • Indian Ocean
    • Amazon Basin
    • Sahara Desert

  11. Compared with 1980, how has the total area of Arctic summer sea ice changed by 2020?

    • Decreased
    • Increased
    • Stayed constant
    • Doubled

  12. Which phrase best describes the trend in Arctic summer sea ice since 1980?

    • Steadily shrinking
    • Rapidly expanding
    • Remaining stable
    • Fluctuating randomly

  13. Which of these is an independent source of physical evidence for recent global warming?

    • Shrinking glaciers
    • Tectonic shifts
    • Lunar phases
    • Solar flares

  14. Why are global sea levels rising as the climate warms?

    • River sedimentation
    • Sinking continents
    • Thermal expansion
    • Increased rainfall

  15. Why does a single unusually hot summer not prove long-term climate change?

    • It is climate
    • It is weather
    • It is seasonal
    • It is artificial

  16. What is the direct physical link between rising air temperatures and Arctic sea ice?

    • Stronger winds create ice
    • Colder air freezes ice
    • Ocean currents stop moving
    • Warmer air melts ice

  17. If a global temperature anomaly rose from plus 0.3 Celsius to plus 1.0 Celsius, what is the change?

    • Rise of 0.7 degrees
    • Drop of 0.7 degrees
    • Rise of 1.0 degrees
    • Rise of 1.3 degrees

  18. Arctic sea ice fell from about 7.5 to about 4.0 million square km between 1980 and 2020. What is the closest percentage fall?

    • About 47%
    • About 20%
    • About 90%
    • About 5%

  19. Why is evidence from several independent scientific sources stronger than from just one?

    • It is faster
    • It stops all debate
    • It is cheaper
    • Agreement reduces error

  20. Which conclusion is best supported by thermometers, shrinking glaciers, and rising seas?

    • Sea levels are falling
    • Glaciers are growing
    • The climate is cooling
    • The climate is warming
