GENERAL KNOWLEDGE

Detailed explanation-1: -Soil erosion is a three phase phenomena, consisting of the detachment of individual soil particles from the soil mass and their transport by erosive agents such as running water and wind.

Detailed explanation-2: -The three stages of soil erosion are: dislodgement, transportation, andsedimentation. Silt is usually preferentially dislodged and transported because clay particles tend to be flocculated and combined in aggregates which increase their mass, and sand particles are larger and heavy.

Detailed explanation-3: -Sheet erosion describes erosion caused by runoff. Rill erosion describes erosion that takes place as runoff develops into discrete streams (rills). Finally, gully erosion is the stage in which soil particles are transported through large channels.

Detailed explanation-4: -Soil erosion, or the loss of all that important stuff, is a natural phenomenon caused by water and wind but can become more of a problem as humans inhabit and develop more of the planet.
