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