    stratosphere
    mesosphere
    thermosphere
  • Thermal energy is ____ when converting from water to ice.
    gained
    lost
  • Not all of the sun's solar radiation is absorbed into Earth, what happens to the rest of the rays?
    It is reflected or radiated back into the atmosphere to become heat energy.
  • Explain the main reason why the amount of ozone in out atmosphere is decreasing.
    Release fo chemical compounds that contain gaseous chlorine or bromine (CFCs) from industry or other human activities.
  • Thermal energy is ____ when converting from water to water vapor.
    lost
    gained
  • Define weather.
    The atmospheric conditions of a certain place at a certain time.
  • How does the atmosphere help the Earth?
    Protects us from ultraviolet radiation
  • Planes fly in the ___ layer of the atmosphere.
    stratosphere
    troposphere
    thermosphere
    mesosphere
  • What is radiation?
    Transfer of heat by electromagnetic waves/rays.
  • How does the greenhouse effect help the Earth?
    Trapping some of the Earth's heat energy so that it doesn't all escape into space.
  • What tool measures temperature?
    psychrometer
    barometer
    thermometer
    anemometer
  • List the different variables that are used to describe weather.
    temperature, air pressure , wind, humidity 
  • True of False: Water will boil more easily at higher altitudes.
    False
    True
  • Name this front.
    occluded
    warm
    stationary
    cold
  • What tool measures wind speed?
    psychrometer
    barometer
    thermometer
    anemometer
  • This type of pressure system will bring generally clear and sunny skies.
    high pressure system
    low pressure system
  • Where does a maritime topical air mass come from and what type of weather desi ut bring?
    comes from the warm temperatures of the Gulf of Mexico and moves northward. The air mass creates more of a chance of storms in southeast & central U.S. region.
  • Name what part of weather g/cm3 measures.
    density
  • Explain why breathing is more difficult at higher altitudes.
    The air at higher altitudes is colder, less dense, and contains fewer oxygen molecules. The air is much thinner.
  • As altitude increases in teh troposphere, the temperature ____.
    increases
    decreases
  • What tool measures air pressure?
    anemometer
    barometer
    thermometer
    psychrometer
  • Name this front.
    warm
    stationary
    occluded
    cold
  • What are the 2 layers of the atmosphere that make up the ionosphere?
    Mesosphere and Thermosphere
  • Expalin waht the meaning of the root word "thermos" means.
    heat
  • Which of the following is the most abundant gas in our atmosphere?
    nitrogen
  • What is the purpose of the ozone layer?
    It absorbs a portion of the sun's radiation, preventing it from reaching Earth's surface.
  • Warm air is less ___ and will ___.
    dense, rise

    thermosphere
    mesosphere
    troposphere
    stratosphere
