The process in which, by the actions of wind or water, soil particles are detached
and transported. - correct-answer - Erosion
Eroded material suspended in wind or water. - correct-answer - Sediment
The deposition of eroded material. - correct-answer - Sedimentation
What bears the impact of quantity and quality degradation from erosion? -
correct-answer - Receiving Waters
, 2
Raindrop impact energy is enough to dislodge surface sediment. - correct-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. - correct-answer - Sheet
Erosion
As flow concentrates, small channels begin to form in the soil surface. - correct-
answer - Rill Erosion
Runoff cuts rills deeper and wider or several rills join to form a large channel. -
correct-answer - Gully Erosion
Channels become unstable due to increased flows or changes in upstream
sediment load. - correct-answer - Channel Erosion
