  • What tool measures air pressure?
    thermometer
    anemometer
    barometer
    psychrometer
  • 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.
  • As altitude increases in teh troposphere, the temperature ____.
    increases
    decreases
  • What tool measures wind speed?
    barometer
    anemometer
    psychrometer
    thermometer
  • Name this front.
    occluded
    stationary
    cold
    warm
  • What type of air can hold more water?
    cold
    warm
  • How deos the atmosphere help the Earth?
    Protects us from ultraviolet radiation
  • 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.
  • Expalin waht the meaning of the root word "thermos" means.
    heat
  • Thermal energy is ____ when converting from water to water vapor.
    lost
    gained
  • True of False: Water will boil more easily at higher altitudes.
    True
    False
  • What are the 2 layers of the atmosphere that make up the ionosphere?
    Mesosphere and Thermosphere
  • Which of the following is the most abundant gas in our atmosphere?
    nitrogen
  • What is the correct order of the atmosphere from lowest to highest.
    troposphere, stratosphere, mesosphere, thermosphere,exosphere
  • List the different variables that are used to describe weather.
    temperature, air pressure , wind, humidity 
  • 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.
  • What is radiation?
    Transfer of heat by electromagnetic waves/rays.
  • What tool measures temperature?
    anemometer
    barometer
    psychrometer
    thermometer
  • Name this front.
    cold
    occluded
    stationary
    warm
  • Name this front.
    occluded
    cold
    warm
    stationary
  • What is the purpose of the ozone layer?
    It absorbs a portion of the sun's radiation, preventing it from reaching Earth's surface.
  • Planes fly in the ___ layer of the atmosphere.
    troposphere
    mesosphere
    thermosphere
    stratosphere
  • 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.
  • Name what part of weather g/cm3 measures.
    density
  • Define weather.
    The atmospheric conditions of a certain place at a certain time.
  • This type of pressure system will bring generally clear and sunny skies.
    high pressure system
    low pressure system
  • As you move through this layer of the atmosphere, the temperatures continue to rise up to 2000 degrees Celsius.
    thermosphere
    troposphere
    stratosphere
    mesosphere
  • This layer of the earth is where weather occurs.
    mesosphere
    thermosphere
    troposphere
    stratosphere
  • 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.
  • Warm air is less ___ and will ___.
    dense, rise
  • Thermal energy is ____ when converting from water to ice.
    gained
    lost
  • Name this front.
    cold
    stationary
