1. What is the numerical value of the Environmental Lapse Rate (ELR) in degrees Celsius per kilometer of rise in altitude?
2. If the temperature at sea level is 30°C, what is the temperature at the tropopause, 16 km up in the atmosphere (use the ELR for this calculation).
3. What is albedo?
4. Calculate the albedo for a cloud that receives 25 units of solar energy and reflects 20 units of that solar energy.
5. What is the name of the layer of the atmosphere where the top of a cumulonimbus anvil head cloud stops rising and spreads out?
6. What is the name of the layer of the atmosphere in which ozone is found?
7. From where does the water come that appears on the outside of a cold can of soda that is sitting outside on a warm day?

9. What is the word for "cloud" in your first language?
10. What does the word "nimbus" refer to in weather and climate class?
11. Why is the sky blue?
12. In terms of energy and the atmosphere, what do carbon dioxide, water vapor, methane, and ozone all do?
13. In our insolation diagram 100 units of sun energy enters the atmosphere.  The atmosphere, however, temporarily stores 160 units of sun energy, 60% more than is put in by the sun?
    1. What is the name for this effect?
    2. Why does this occur?
14. What are the colors of the sun as seen in a rainbow in English?
