which of the following?

1. The atmosphere
2. Estuaries
3. Lakes
4. Rivers and streams
5. Polar ice caps and glaciers

E. Polar ice caps and glaciers
4
Overuse of groundwater in coastal areas would
most likely result in which of the following

1. Rise in water table
2. Increase in stream flow
3. Bacterial contamination of surface water
4. Saltwater intrusion
5. Decrease in eutrophication

D. Saltwater intrusion
5
Which of the following is a measure of the
amount of suspended material in water?
a. Salinity b. Turbidity c. Trace-metal
concentration d. Leachate concentration e. pH
B. turbidity
6
Which of the following is a common characteristic
of lakes undergoing cultural eutrophication?

1. Decreased rates of sediment accumulation
2. Decreased amounts of green and blue-green algae
3. Increased levels of oxygen throughout the water
   column
4. Increased water clarity in the epilimnion
5. Increased levels of plant nutrients

E. Increased levels of plant nutrients
7
In a river ecosystem, dissolved oxygen
concentrations drop quickly downstream from a
point-source input of organic matter into the
river. This effect is due to

1. Increasing populations of mayfly and stonefly
   larvae
2. Increasing activity of trout and black bass
3. Increasing bacterial activity as organic matter
   decays
4. Decreasing bacterial activity as turbidity
   increases
5. Decreasing water temperatures as surface
   evaporation increases

C. Increasing bacterial activity as organic
matter decays.
8
When logging is carried out in a watershed, a
likely effect on the local streams is

1. Mitigation of anoxia
2. Decreased nutrient levels
3. Decreased input of sediments
4. Increased oligotrophic conditions
5. Increased water temperature

E. Increased water temperature
9
Which of the following is true of carbon as it
cycles in nature?

• Carbon dioxide is released during photosynthesis
• Carbon compounds rarely exist in the gaseous
  state
• Carbon sinks include forests and oceans
• The carbon dioxide concentration in the
  atmosphere
• is reduced by cutting trees.
• e. Carbon is concentrated in igneous rocks.

c. Carbon sinks include forests and oceans
10
The process in the hydrologic cycle in which
water vapor is releases from leaves into the
atmosphere is called

1. Infiltration
2. Transpiration
3. Sublimation
4. Reflection
5. Percolation

B. transpiration
11
A field is abandoned, and an invasive plant that
can live in nutrient-poor soil moves into the
field. If the land is later cleared of this
invasive species and it is discovered that the
soil has an abundance of nitrogen compounds, what
conclusion can best be made?

• The plants used up all of the phosphorous and
• potassium and left the nitrogen behind
• b. Primary succession always produces an
  abundance of nitrogen
• c. Bacteria in soil and in root nodules converted
  free nitrogen into
• nitrogen compounds.
• d. The plants were able to produce nitrogen in
  their leaves.
• e. More rock was weathered and broken down to
  release nitrogen
• compounds.
