WATER PLANET EXAM 2 QUESTIONS
AND ANSWERS GRADED A+ 2025/2026
What is a Natural Capital? - ANS natural resources and services
What causes the depletion of oxygen in polluted waters? - ANS enrichment in Nitrogen
causes an algal bloom and the algae consume all the oxygen
Air pollution in LA in the 1950s and 60s was as bad as anywhere in the world today - what was
the most important step in reducing air pollution: - ANS regulating vehicle emissions
What is the primary productivity in the above plot (look at the units)? - ANS the conversion
of energy input into biomass (plant growth) (energy converted per unit land are per year)
Why are high heat capacity (hc), high thermal conductivity (tc), and high latent heat of
vaporization (lhofv) key attributes that make water so effective in supporting animal life? -
ANS these properties together make water an effective coolant-absorbing heat, transporting
it, then cooling during the evaporation of sweat
About how long would your brain survive if its cooling system shut down? - ANS only about
40 minutes

The best way to help a salmon run recover after successful dam removal is to build a large fish
hatchery to introduce as many salmon as possible into the river. - ANS false
The 4 Lower Snake River dams have been characterized as: - ANS greatly impacting one of
the largest salmon fisheries while providing relatively little benefit in terms of flood control,
water supply, or hydro-electric power
What percent of Arizona's land base is "riparian"? - ANS .4%
What is the name of the legal doctrine that determines surface water rights in the West? -
ANS Doctrine of prior appropriation
What does C.A.P. stand for? - ANS Central Arizona Project
Which represents by far the greatest consumptive use of water in the Colorado River Basin? -
ANS Irrigation
71% growing hay to feed cattle, feeding cities
What is a managed aquifer? - ANS an aquifer used by municipalities to store and purify
reclaimed water for land use
