, Section 1: Erosion and Sediment Control Fundamentals
1. A slope gradient of 25% (4:1) would indicate that in a horizontal length of 100 feet, the
vertical rise would be ______ feet.
A) 2.5
B) 12.5
C) 25
D) 4
Answer: C) 25
Rationale: A 25% slope means a 25-foot rise for every 100 feet of horizontal distance (25/100 =
25%).
2. As rain falls to the earth, what is the very first function of vegetation?
A) It reduces detachment
B) It increases infiltration
C) It absorbs raindrop impact
D) Roots hold soil in place
Answer: A) It reduces detachment
Rationale: Vegetation's first defense is intercepting rainfall and reducing the energy of raindrop
impact, which prevents soil particles from being dislodged (detached).
3. Because of the likelihood of thunderstorms, which is the worst month to schedule land
disturbing activities?
A) April
B) July
C) September
D) October
Answer: B) July
Rationale: July typically has the highest frequency of thunderstorms in many regions, making it
the riskiest month for land disturbance.
