CPESC EXAMINATION TEST 2026 QUESTIONS
WITH ANSWERS GRADED A+
◉ Eroded material suspended in wind or water. Answer: Sediment
◉ The deposition of eroded material. Answer: Sedimentation
◉ What bears the impact of quantity and quality degradation from
erosion?. Answer: Receiving Waters
◉ Raindrop impact energy is enough to dislodge surface sediment.
Answer: Splash Erosion
◉ Rain splash detaching soil particles lifting them up and removing
them by shallow "sheets" of water flowing down the sloped soil surface.
Answer: Sheet Erosion
◉ As flow concentrates, small channels begin to form in the soil surface.
Answer: Rill Erosion
◉ Runoff cuts rills deeper and wider or several rills join to form a large
channel. Answer: Gully Erosion
, ◉ Channels become unstable due to increased flows or changes in
upstream sediment load. Answer: Channel Erosion
◉ Can happen when erosion left unattended. Answer: Slope Failure
◉ Erosion due to the influence of climatic forces on the surface of the
earth. Answer: Natural Erosion
◉ Natural Erosion + Human Activities. Answer: Accelerated Erosion
◉ 1. Unrestricted development
2. Removal of surface cover
3. Increased Imperviousness
4. Poor stewardship. Answer: What can accelerate erosion?
◉ 1. problems for downslope property owners
2. problems on adjacent streets
3. clog streams and storm drains
4. cause turbidity blumes in downstream water bodies
5. cumulative toll on the environment can be devastating. Answer:
Construction related erosion can cause what problems?
