          The Earth’s Atmosphere Test Study Guide
Is Air Matter? Activities
    1. Does air have mass? How do you know?


   2. Does air take up space? How do you know?


   3. Is air matter? Explain.


Characteristics of the Atmosphere: Composition and Pressure
  1. What is the atmosphere?


   2. What is the first and second most common gas in the atmosphere?

   3. What is water vapor?

   4. What is air pressure?


   5. What happens to air pressure as you go higher in the atmosphere?


Air Pressure Demonstrations
   1. What holds the earth’s atmosphere in place?

   2. What is the air pressure inside a vacuum?

   3. Why does a balloon pop in a vacuum (explain or draw a picture)


   4. What happens to a marshmallow if you put it in a vacuum and then let the
      air back in? Explain why.



   5. Why did the teacher heat the air inside the bottle? What did this cause the
      air to do?



   6. Explain why the egg went into the bottle after the air was heated.
   Brainpop: The Earth’s Atmosphere & Layers of the Atmosphere

Label each layer of the Atmosphere:Troposphere, Stratosphere. Mesosphere,
Thermosphere. Exosphere, Ozone Layer

   1.   The uppermost layer of the atmosphere ____________________
   2.   The layer that contains the ozone layer. ____________________
   3.   The coldest layer of the atmosphere. ______________________
   4.   The layer we live in and where all weather occurs. _______________
   5.   The hottest layer of the atmosphere _______________________
   6.   It protects us from the sun’s ultraviolet radiation. ______________

Radiation, Conduction, or Convection (Diagram and Worksheet)

   1. __________________ is the traveling of energy waves through space.
   2. __________________ is heat traveling in a circular motion due to unequal
      heating.
   3. _________________ is the direct transfer of heat from one substance to
      another. For example the ground absorbs ___________ from the sun and
      releases it as _______. This heat energy is then transferred directly to the
      air above it.

Be able to recognize pictures that show conduction, radiation or convection.

Convection Current Lab

   1. How will a fluid (air or water) travel if it is heated? Explain why by
      discussing density.




   2. How will a fluid (air or water) travel if it is cooled? Explain why by
      discussing density.



   3. Why does air rise from the surface of the earth?



   4. Why does air sink when it reaches higher elevations?
Direct and Indirect Rays of the Sun Activities

1. Why is the equator warmer than the poles?


Greenhouse Effect Notes

   1. What happens to the radiation from the sun when it reaches the earth?


   2. What is the Greenhouse Effect?


   3. What are greenhouse gases – name the most important one.


   4. What is global warming?



   5. What could happen if the earth experiences global warming?



Greenhouse Lab and Diagram of Greenhouse Effect

   1. Explain or draw a diagram to show why a greenhouse acts like the gases
      in our atmosphere to hold in heat.




   2. What does the glass of a greenhouse represent in our atmosphere?


   3. What human activities contribute to the rise of greenhouse gases in our
      atmosphere?



   4. What planet in our atmosphere is a great example of the greenhouse
      effect? Explain.
