  • If you were collecting data and providing evidence of typical weather patterns of a certain area, what would you would NOT need to know?: -wind speed or -number of stars in the sky
    number of stars in the sky
  • The measure of the amount of water vapor in the air.
    air pressure
    humidity
    temperature
    precipitation
  • What's the unit of measurement used for wind speed?
    km per hour
  • If you were collecting data and providing evidence of typical weather patterns of a certain area, what would you would NOT need to know: -temperature, -moon phase, -wind direction
    moon phase
  • If you have a diagram of some air in a syringe showing 8 dots (to represent the air particles) in the uncompressed syringe, how many dots should you draw in the compressed syringe?
    8 dots
  • What is the unit(s) of measurement used for temperature? (2 answers)
    degrees Celcius/degrees Fahrenheit
  • What is used to measure air pressure?
    barometer
  • If you were collecting data and providing evidence of typical weather patterns of a certain area, what would you would NOT need to know?: -air pressure, -humidity, -number of daylight hours
    number of daylight hours
  • What is used to measure wind direction?
    wind vane
  • When you push down on a closed syringe, the air molecules ...
    become less dense
    are pushed closer together and are more densely packed
    get smaller and stay near the bottom
  • What is the unit of measurement used for air pressure?
    millibars
  • As you go higher into the atmosphere, the air pressure ..
    increases
    stays the same
    decreases
  • What occurs when air is forced into a smaller space?
    weight
    force
    compression
    expansion
  • What do you use to measure temperature?
    Thermometer
  • True/False - Daily weather records help identify patterns of stable versus changeable weather conditions.
    True
  • What is the unit of measurement used for wind direction?
    north, south, east, west
  • Meteorologists record weather conditions multiple times each day to
    let us know what to wear
    give old people something to talk about
    identify patterns over time to make predictions
    identify all the factors that contribute to a weather system
  • The force of air on a surface; when increased, will result in increased temperature and density.
    Humidity
    Air Pressure
    temperature

    no change
    slower
    faster
