    troposphere
    mesosphere
    stratosphere
    thermosphere
  • Which of the following is the most abundant gas in our atmosphere?
    nitrogen
  • Name this front.
    stationary
    warm
    cold
    occluded
  • What tool measures temperature?
    thermometer
    psychrometer
    barometer
    anemometer
  • Expalin waht the meaning of the root word "thermos" means.
    heat
  • What is the purpose of the ozone layer?
    It absorbs a portion of the sun's radiation, preventing it from reaching Earth's surface.
  • What are the 2 layers of the atmosphere that make up the ionosphere?
    Mesosphere and Thermosphere
  • Name what part of weather g/cm3 measures.
    density
  • This layer of the earth is where weather occurs.
    stratosphere
    thermosphere
    mesosphere
    troposphere
  • Name this front.
    warm
    cold
    occluded
    stationary
  • 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.
  • Thermal energy is ____ when converting from water to ice.
    gained
    lost
  • What type of air can hold more water?
    cold
    warm
  • List the different variables that are used to describe weather.
    temperature, air pressure , wind, humidity 
  • 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.
  • How does the atmosphere help the Earth?
    Protects us from ultraviolet radiation
  • 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.
  • Thermal energy is ____ when converting from water to water vapor.
    gained
    lost
  • True of False: Water will boil more easily at higher altitudes.
    False
    True
  • Warm air is less ___ and will ___.
    dense, rise
  • Name this front.
    stationary
    cold
    warm
    occluded
  • This type of pressure system will bring generally clear and sunny skies.
    low pressure system
    high pressure system
  • What tool measures air pressure?
    psychrometer
    thermometer
    barometer
    anemometer
  • What tool measures wind speed?
    anemometer
    psychrometer
    thermometer
    barometer
  • Planes fly in the ___ layer of the atmosphere.
    thermosphere
    mesosphere
    stratosphere
    troposphere
  • 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 is the correct order of the atmosphere from lowest to highest.
    troposphere, stratosphere, mesosphere, thermosphere,exosphere
  • Name this front.
    stationary
    occluded
    cold
    warm
  • As altitude increases in teh troposphere, the temperature ____.
    decreases
    increases
  • 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.
  • Define weather.
    The atmospheric conditions of a certain place at a certain time.
  • What is radiation?
    Transfer of heat by electromagnetic waves/rays.
