The 20 questions

  1. What is the minimum sea surface temperature required for a tropical storm to form?

    • 27 degrees Celsius
    • 18 degrees Celsius
    • 35 degrees Celsius
    • 10 degrees Celsius

  2. What minimum sea surface temperature is required to fuel a tropical storm?

    • 10 degrees
    • 15 degrees
    • 27 degrees
    • 40 degrees

  3. Which of these is NOT a required condition for tropical storm formation?

    • Low wind shear
    • Warm ocean water
    • Heavy snowfall
    • Coriolis effect

  4. What does wind shear describe in the atmosphere?

    • Maximum air pressure
    • Constant wind direction
    • Varying wind speeds
    • Zero wind speed

  5. Which phenomenon causes a developing tropical storm to rotate?

    • Coriolis effect
    • Foehn effect
    • Rain shadow effect
    • Greenhouse effect

  6. Why do tropical storms fail to form directly on the Equator?

    • Water is too cold
    • High atmospheric pressure
    • Excessive wind shear
    • Insufficient Coriolis force

  7. Why does a tropical storm rapidly weaken once it makes landfall?

    • Increased land heat
    • Stronger wind shear
    • Loss of fuel
    • Higher air pressure

  8. What process occurs when rising moist air cools inside a storm?

    • Condensation
    • Sublimation
    • Transpiration
    • Evaporation

  9. What energy is released during cloud condensation to fuel a storm?

    • Geothermal heat
    • Kinetic energy
    • Latent heat
    • Solar radiation

  10. What is the initial trigger in the sequence of tropical storm formation?

    • Rising warm air
    • High pressure sinking
    • Cold water freezing
    • Landmass friction

  11. Between which latitudes do the majority of tropical storms develop?

    • 30 and 60
    • 5 and 30
    • 0 and 5
    • 60 and 90

  12. Over which major water body do hurricanes typically develop?

    • Arctic Ocean
    • Atlantic Ocean
    • Southern Ocean
    • Mediterranean Sea

  13. During which season are tropical storms most frequent in the Northern Hemisphere?

    • Early spring
    • Late summer
    • Deep winter
    • Mid-spring

  14. What happens when a hurricane moves from the ocean onto a continent?

    • It intensifies
    • It broadens
    • It weakens
    • It accelerates

  15. Which environmental condition is ideal for tropical storm genesis?

    • Cold polar current
    • Arid desert basin
    • Warm ocean surface
    • High mountain range

  16. What atmospheric factor prevents tropical storms from forming at 0 degrees latitude?

    • High atmospheric pressure
    • Low water temperature
    • Zero Coriolis effect
    • Extreme wind shear

  17. What minimum sea surface temperature is required for a tropical storm to form?

    • 20 degrees Celsius
    • 27 degrees Celsius
    • 15 degrees Celsius
    • 35 degrees Celsius

  18. Which process transfers heat and moisture from the warm ocean to power a tropical storm?

    • Transpiration
    • Condensation
    • Precipitation
    • Evaporation

  19. What is the most likely effect of climate change warming the world's oceans?

    • No change
    • Fewer storms
    • Stronger storms
    • Weaker storms

  20. Which condition provides the crucial rotational spin for a tropical storm to develop?

    • Coriolis effect
    • Atmospheric pressure
    • Deep ocean currents
    • High wind shear
