    The sun
  2. What type of air masses bring cold, dry air which affects the northern US during the winter months?
    continental polar
  3. If you live far from the ocean, it is likely you will have a ______________ climate?
    continental
  4. Where on Earth do the sun's rays hit least directly?
    the poles
  5. Earth's atmosphere traps energy from the sun. This allows water to exist as a ____________?
    liquid
  6. What does the tilt of Earth's axis as it revolves around the sun cause?
    the seasons
  7. Where do the sun's rays hit most directly?
    the equator
  8. What best describes what scientists measure when they compare the readings of wet and dry bulb thermometers?

    a. temperature
    b. moisture in the air
    c. wind speed
    d. relative humidity
    e. humidity
    d. relative humidity
  9. What do meterologists say are caused by uneven heating within short distances or small areas?
    local winds
  10. What are caused by uneven heating over long distances or larger areas?
    global winds
  11. What happens to solid molecules when they are heated?

    a. move closer together
    b. move further apart
    c. they stay the same
    move further apart (fast moving/less dense)
  12. Molecules in cooler substances______________.

    a. don't move
    b. are moving faster
    c. are moving slower
    c. are moving slower (more dense/closer together)
  13. Convection takes place because ______________ air is more dense than ______________ air.

    a. warm/cold
    b. cold/warm
    c. chilly/hot
    b. cold/warm
  14. Water vapor is water in the form of a _________.

    a. solid
    b. water droplets
    c. steam
    d. a gas
    d. a gas
  15. Which of the following are part of the water cycle?

    a. conduction/radiation/saturation/precipitation
    b. conduction/precipitation/saturation/convection
    c. evaporation/condensation/saturation/precipitation
    d. convection/conduction/precipitation/condensation
    c. evaporation/condensation/saturation/precipitation
  16. Mild marine climates, like much of the west coast of the US, have _______winters and _______summers.
    relatively warm winters and cool summers
  17. What often happens when air moves from high pressure toward low pressure?
    winds
  18. _________ are caused by differences in air pressure and temperature?
    winds
  19. Air pressure decreases as you move away from the Earth. Further in the atmosphere, however,
    air pressure first
    __________then____________.
    increases, then decreases
  20. Air in the atmosphere has pressure, because air has ____________?
    mass
  21. Land cooling off faster than water causes ___________ breezes.
    land
  22. Winds are caused by differences in_________________.
    air pressure
  23. Why does one hemisphere have summer at the same time the other hemisphere has winter?
    • Due to the tilt of the Earth on its axis, one hemisphere receives direct rays/energy from the sun, causing warmer temperatures during the summer months. The opposite hemisphere receives least direct
    • rays/energy from the sun at the same time, causing colder winter temperatures.
  24. Why does lake effect snow occur?
    Cold, dry air masses from the north travels over the great lakes. Land around the lakes cools down a lot faster than the water in the lakes. Warmer lake water is evaporated as the air mass travels over the warm water. The water vapor from the lake rises, cools, reaches its dew point, and condenses forming a lot of clouds. The clouds saturate and eventaully fall to Earth as a lot of precipitation/snow around the lake.
  25. What are the names of the two snowiest cities in the US? Where are they located?
    Rochester, NY and Buffalo, NY
  26. What is your weather prediction with the following data collected from weather instruments?

    Temperature: 21 degrees fahrenheit
    Relative humidity: 84%
    Air Pressure: 29.5 inches and falling
    Cloud Cover: 85 %
    Cloud Type: Nimbostratus
    Prediction: cold/snow likely within the next 12-24 hours
