, What is erosion? Answer - The process by which soil particle get displaced by the
act of wind of water.
What are the three types of Wind Erosion? Answer - 1. Creep - causes sand dunes
<10%
-large particle that roll across a terrain
2. Saltation - bouncing particles that DISLODGE more particles, then fall back down
~50-80%
- stay relatively close to ground
3. Suspesion - suspended way up into the atmosphere
~ 5-25%
-light weight soil particles dusted in the air
Which method of wind erosion moves the most soil? Answer - Saltation
What are the types of water erosion? Answer - Raindrop erosion
Sheet erosion
Rill and Gully erosion

Shoreline erosion - by the act of waves
Landslides - difficult to prevent
Raindrop Erosion Answer - dislodges many soil particles
Sheet Erosion Answer - stripping away a thin sheet of topsoil from the surface of the
land
-flat lands where water flows ontop due to runoff
-can transport large amounts of soil
-causes additional erosion
Rill and Gully Erosion Answer - If the runoff is allowed to concentrate and gain
velocity or energy, it will cut rills and gullies as it detaches more soil particles
Rills: < or = to 3in. deep
Gullies: Three of more rills that convered to greater than 3in. deep
What factors impact rainfall erosion? Answer - -Climate events
-Soil erodibility
-The length of flow over a distance/ How Far
-Rate of flow
-The angle of the slope
-Vegetative cover
-Erosion and Sediment controls (BMPs)
What is Sediment? Answer - The eroded material that settles in water or air.
