a)
salt water in the oceans
b)
fresh water in glaciers/ice
c)
fresh water in groundwater
d)
freshwater in lakes/rivers/streams
salt water in the oceans
The process which moves water from the oceans to the atmosphere is called:

precipitation
b)
evaporation
c)
condensation
d)
infiltration

infiltration
The majority of freshwater on the planet is:
Question options:
a)
groundwater
b)
surface water (lakes/rivers/streams)
c)
biological water (in plants and animals)
d)
frozen (glaciers/ice caps)
frozen (glaciers/ice caps)
For each item below, indicate whether it increases or decreases the evaporation rate of water (graded as all or nothing).
__1__
hotter conditions
__1__
windy conditions
__2__
more humid conditions
1.
increases evaporation
2.
decreases evaporation
The energy for evaporation of water on the planet comes mainly from:
Question options:
a)
the sun
b)
nuclear energy
c)
wind energy
d)
isotppic decay
the sun
Despite the fact that thermoelectric water usage is the largest usage of water in the US, we focus on water used in agriculture (irrigation) when discussing issues concerning sustainable water practices - why?
Question options:
a)
Because there is more fertilizer use in agricultural practices
b)
because water is taken from one place and used in another during agricultural practices, thereby affecting the natural hydrologic cycle
c)
because water is often returned to the place it was taken from in thermoelectric, thereby not changing the natural hydrologic cycle
d)
because thermoelectric water is not the same water we would use for agricultural water - they use separate water sources.
e)
all of the above
f)
b and c only
g)
a and c only
because water is taken from one place and used in another during agricultural practices, thereby affecting the natural hydrologic cycle and because the water is often returned to the place it was taken from in thermoelectric, thereby not changing the natural hydrologic cycle. (B and C only)
The process plants use to make energy is called:
Question options:
a)
transpiration
b)
photosynthesis
c)
evapotranpiration
photosynthesis
Transpiration:
Question options:
a)
is the process of evaporating water out of stomata in plant leaves
b)
releases CO2 back to the atmosphere
c)
takes in CO2 from the atmosphere
d)
is a process done by animals
e)
all of the above
f)
a and b only
g)
a, b, and c only
is the process of evaporating water out of stomata in plant leaves (plants breathing)
Evapotranspiration is the combination of evaporation of water directly from soils and the transpiration of water from plants. Question options: a) true b) falsetrueEvapotranspiration rates are affected by the same factors that affect evaporation rates, namely temperature, humidity, and wind conditions, but also by plant type and plant health/agetrueAll plants have the same water requirements. Question options: a) true b) falsefalseA consumptive use of water is: Question options: a) one where water is removed from its place in the hydrologic cycle for some purpose but not returned back to that same place in the hydrologic cycle after it is used. b) one where water is removed from its place in the hydrologic cycle for some purpose and after it is used is returned back to that same place in the hydrologic cycle.one where water is removed from its place in the hydrologic cycle for some purpose but not returned back to that same place in the hydrologic cycle after it is used
