BIS2B, Fall 2009. STUDY QUESTIONS Lectures 4, 5, 6 1. We have discussed two kinds of data gathered by MODIS and similar satellites. The first is the ratio of reflected near infrared, NIR to visible light, V. The ratio is NIR/V. What wavelengths of light does living vegetation absorb? ___________________________________________. 2. Dense vegetation will reflect a relatively _______________NIR/V to MODIS. 3. Sparse vegetation will reflect a relatively _______________NIR/V. 4. Why does the ratio vary as in questions 2 and 3?______________________________________________________________________ _______________________________________________________________________ 5. Deciduous means____________________________________________________? 6. Ceciduous vegetation has no leaves (when) _______________at high latitude and _________________(when?) at low latitiude. 7. Evergreen vegetation bears leaves __________________________________(when?). 8. The ratio of NIR/V in deciduous forests is greatest in ____________________at high latitude and ____________________________at low latitude. 9. Why? In Answer in 8. _________________________________________________. 10. Another variable measured by MODIS is evapotranspiration, ET, which is________.- _____________________________________________________________________. 11. Where there is no evaporation, such as in a growth chamber in a lab, what is the name of the plant physiological process that exchanges CO2, O2, and H20 with the atmosphere? 12. Water produced by evapotranspiration enters plants via the ______________. 13. Water produced by evapotranspiration is released to the atmosphere via the ______________. 14. Which are on ________________________(from question 13). 15. The two kinds of gases released to the atmosphere by plants during ET are _______________________and ___________________________. 16. The gas taken up by the plant during ET is________________________. 17. EP has two components ___________________ and __________________. 18. Where there are no vascular plants, all of the moisture entering the atmosphere is from__________________________________.
