APES Water Unit Test Review with
Complete Solutions
97%/3% - ANS-What % of Earth's water is saltwater? ... freshwater?
Ice caps/Glacier - ANS-The majority of Earth's freshwater is located...
Groundwater - ANS-The largest accessible supply for drinking is located...
x2 - ANS-Demand for water compared to global population growth?
Distillation
Reverse Osmosis - ANS-What are the 2 different types of desalination techniques?
PS = direct discharge from paper, meat packing plants, and sewage discharge
NPS= indirect sources from urban run off (pet feces, fertilizers, leaves) & agricultural
runoff (feed lots, fields) - ANS-What's the difference between point source and non-point
source pollution?
BOD- demand on o2 from organisms much
DO - dissolved oxygen "mixed-in" w/water - ANS-What's the difference between DO and
BOD?
blue baby syndrome - ANS-Improper percolation in the drainfield of a septic system can
allow NH4+ (ammonia) from urine to get into the drinking water supply. It can cause
"methemoglobinemia," What is this condition commonly known as?
warm = low oxygen levels
rough fish (carp/bullheads)
Algae blooms
High nutrients
Low dissolved 02 levels
shallow - ANS-List a few characteristics of eutrophic lakes
epilimnion-upper
thermoculine- greatest change in temp
hypolimnion-highest nutrient input - ANS-Know the difference between: epilimnion,
thermocline, hypolimnion
summer - ANS-What season in our region shows thermal lake stratification?
