13. Earth's temperature is about 300K and the surface of the sun is 6000K. How much more energy would a body with the temperature of the sun radiate compared to a similar-size body at Earth's temperature? (show work)

14. How does the "greenhouse effect" work in the Earth-Atmosphere system?

15. Describe the operation of a “Hadley Cell”.

16. Why is the “greenhouse effect” a good thing and not a bad one (contrary to popular misconceptions)?

17. Why is the world-wide production of many metals related to plate tectonics? Are there other factors that also may influence production?

18. Draw a diagram of the temperature structure of the atmosphere in the lowest 2 layers. Try to be accurate with heights and temperatures, and label the 2 layers.

19. Write out the equation for photosynthesis with all of its reactant and products.

20. What is the ITCZ and why does its position change throughout the year?

21. What is albedo and how could it be manipulated to reduce global warming? (see Benford reading)

22. What is the peak wavelength at which you are emitting radiation? (if you are not emitting radiation, why not?)

23. Explain how weather is different from climate. If we set a record temperature this year, does that indicate climate change?

24. Describe 2 properties of water related to its polar nature.

25. What 3 atmospheric greenhouse gases have been increasing very rapidly in the last 150 years?

26. Draw a low pressure system and show how the winds circulate around it (Northern Hemisphere).
