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