Question 1: The process in which, by the actions of wind or
water, soil particles are detached and transported.
CORRECT ANSWER : Erosion
Question 2: Eroded material suspended in wind or water.
CORRECT ANSWER : Sediment
Question 3: The deposition of eroded material.
CORRECT ANSWER : Sedimentation
Question 4: What bears the impact of quantity and quality
degradation from erosion?
CORRECT ANSWER : Receiving Waters
Question 5: Raindrop impact energy is enough to dislodge
surface sediment.
CORRECT ANSWER : Splash Erosion
Question 6: Rain splash detaching soil particles lifting them
up and removing them by shallow "sheets" of water flowing down the sloped soil surface.
CORRECT ANSWER : Sheet Erosion
Question 7: As flow concentrates, small channels begin to
form in the soil surface.
CORRECT ANSWER : Rill Erosion
Question 8: Runoff cuts rills deeper and wider or several rills
join to form a large channel.
CORRECT ANSWER : Gully Erosion
Question 9: Channels become unstable due to increased flows
or changes in upstream sediment load.
CORRECT ANSWER : Channel Erosion
