Questions With Verified Answers
Chapter 1
Erosion - answer✔The process by which the land surface is worn away by the action of wind,
water, and gravity
Sedimentation - answer✔Is the settling out of soil particles transported by water and wind
Two classifications of soil erosion - answer✔1. Wind erosion 2. Water erosion
Two classifications of water erosion - answer✔1. Overland 2. Stream
Overland erosion - answer✔Occurs on denuded slopes when raindrops splash and run off
Stream channel erosion - answer✔Occurs as the volume and velocity of flow increases
sufficiently to cause the movement of the streambed and bank materials.
Four proccesses of Overland erosion - answer✔1. Splash or raindrop - results when raindrops
dislodge soil particles as splash them into the air.
2. Sheet erosion - caused by shallow sheets of water flowing off the land.
3. Rill erosion - develops as the shallow surface flow begins to concentrate in low spots
4. Gully erosion - occurs as the flow in rolls comes together in larger and larger channels.
The major difference between gully and rill erosion - answer✔Size
