Question 1: A construction site manager notices that after a heavy rainstorm,
the soil surface appears uniformly lowered across a large area with no visible
channels. What type of erosion is most likely occurring?
A. Rill erosion
B. Gully erosion
C. Sheet erosion
D. Channel erosion
Correct Answer: C
Rationale: Sheet erosion occurs when a thin, relatively uniform layer of water
flows across the soil surface, removing soil particles evenly. It is often difficult
to detect because there are no distinct channels or rills formed.
,Question 2: During a site inspection, an inspector observes small, narrow
channels forming in the soil that are shallow enough to be smoothed out by a
tiller. What type of erosion is this?
A. Sheet erosion
B. Rill erosion
C. Gully erosion
D. Splash erosion
Correct Answer: B
Rationale: Rill erosion is characterized by the formation of small, concentrated
flow paths called rills. These are narrow and shallow enough to be removed
by normal tillage operations, distinguishing them from gullies.
Question 3: A developer is clearing a large tract of land for a new subdivision.
Which of the following factors is most likely to accelerate erosion on the site?
A. Increased vegetative cover
B. Removal of surface cover
C. Reduced imperviousness
D. Decreased slope gradient
Correct Answer: B
Rationale: Removal of surface cover is a major factor that accelerates erosion.
Vegetation protects the soil from raindrop impact, slows runoff, and helps
,bind soil particles together. When it is removed, the soil is left exposed and
vulnerable.
Question 4: An environmental scientist is evaluating the impact of a
construction project on a nearby stream. She notes that sediment from the
site has filled in the spaces between gravel in the streambed. What is this
impact called?
A. Turbidity
B. Filling of channels
C. Destruction of spawning areas
D. Direct toxicity to wildlife
Correct Answer: C
Rationale: The filling of spaces between gravel in a streambed with fine
sediment is a significant impact on aquatic habitat. It destroys spawning areas
for fish and other organisms that rely on clean gravel for reproduction.
Question 5: What is the primary purpose of the Clean Water Act?
A. To regulate drinking water quality
B. To restore and maintain the chemical, physical, and biological integrity of
the Nation's waters
C. To promote economic development in coastal areas
D. To manage federal lands
, Correct Answer: B
Rationale: The Clean Water Act's stated goal is to restore and maintain the
chemical, physical, and biological integrity of the Nation's waters. This
includes eliminating pollutants and restoring waters to their designated uses.
Question 6: A state agency is issuing a certification for a project that may
discharge pollutants into navigable waters. Under which section of the Clean
Water Act is this certification required?
A. Section 402
B. Section 404
C. Section 401
D. Section 303
Correct Answer: C
Rationale: CWA Section 401 requires a Water Quality Certification for any
applicant for a federal permit to conduct an activity which may result in the
discharge of any pollutant into waters of the United States. The certification is
granted by the state.
Question 7: The Army Corps of Engineers is responsible for administering
which section of the Clean Water Act?
