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