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