Water vapor is not a major greenhouse gas. [1 pt] 7. T or F. Composting is an anaerobic biological process. [1 pt] 8. T or F. Dec aying garbage in a landfill generates methane during the initial aerobic decomposition of the garbage. [1 pt] T or F. The City of Portland reached its recycle goal of 75% in 2015. [Extra credit: 1 pt 9. The following questions are True or False and Why? No credit given unless you answer why. 10. T or F. Why? Just upstream of the point in the river where the maximum dissolved oxygen deficit (or Cmin) occurs, the slope of the C vs x curve is negative implying that the rate of reaeration is >the rate of BOD decay. 12 pts] 11. T or F. Why? During a temperature inversion, the values of E, and Ey are very small, but during a temperature profile that follows the adiabatic lapse rate, E and Ey are much larger. [2 pts] 12. T or F. Why? The source/sink terms for BOD in t he epilimnion and the hypolimnion in a stratified lake are the same. [Extra credit 1 pt 13. T or F. Why? The source/sink terms for dissolved oxygen in the epilimnion and hypolimnion of a stratified lake are the same. [Extra credit 1 pt]Explanation / Answer
5) True
The greenhouse gases in the atmosphere absorb most of the long-wave infrared radiation emitted by the Earth, which heats the lower atmosphere.
6) True
Water vapour is the important greenhouse gas. Affects the temperature of the Earth. It is the largest contributor to the greenhouse effect of the Earth. It probably accounts for about 60% of the heating effect.
7) False
It is an aerobic biological process that uses natural micro-organisms to convert biodegradable organic matter into a humus-like product.
8) False
Anaerobic bacteria break down organic waste to produce biogas, which consists of methane and carbon dioxide along with traces of other compounds.
