Throughout this test work quietly.

1. ______________________ Cloud type
2. ______________________ Cloud type
3. ______________________ Cloud type
4. ________________________________________ What is the name of the lowest layer of the atmosphere?
5. Carbon dioxide contributes to global warming. What absorbs carbon dioxide and removes it from the atmosphere?
6. Describe the process that produces the typical daily rain on Pohnpei.
7. How do we know that the Bergeron process is not producing our typical daily rain on Pohnpei?
8. __________________ An El Niño brings what kind of weather to Micronesia?
9. __________________ What are we in now, an El Niño or a La Niña?
10. __________________ When are the Eastern Carolines, Kosrae and Pohnpei, more likely to have tropical storms and typhoons, during an El Niño or a La Niña?
11. The diagram on the right depicts two different sound waves as might be seen on an oscilloscope. One wave is like that which is produced by a whistle or tuning fork, the other wave is like that which is produced by a blowing into a PVC pipe. Correctly label one wave as the whistle/tuning fork wave and the other as the PVC pipe wave.
12. Sketch a wave with a wavelength of 10 cm and an amplitude of 2 cm. Label your diagram.
13. __________________ Given that v = λ f, what is the velocity of a wave on a chain with a wavelength λ of 48 cm and a frequency f of 3.8 Hertz?
14. __________________ Students who were 86.0 meters from the classroom building banged two boards in synch with the bang board echo. 30 claps of the wood boards took 14.7 seconds. What was the speed of sound in meters per second based on this experiment?
15. List the colors that can actually be seen in a visible light spectrum in order from lowest frequency/longest wavelength to highest frequency/shortest wavelength.
16. List the colors in the "Newtonian" spectrum in order from lowest frequency/longest wavelength to highest frequency/shortest wavelength.
17. Toughie: In terms of frequency and wavelength the sun produces a continuous color spectrum. The fluorescent lights, however, produced four to five distinct single colors. What does this mean in terms of the frequencies and wavelengths being produced by the fluorescent lights?
18. __________________ When spear fishing in shallow water on the reef, does the experienced spear fisher aim above or below the fish that he sees in the water?
19. What happens to the human eye's crystalline lens with increasing age?
20. What effect does this aging of the lens have on people? Be specific.
21. ____________________________________ What is the scientific name for this aging of the lens effect?
22. What can a person do to remedy (fix) this aging of the lens effect?
