c. What is soil erosion? Mention three steps that could be taken to prevent soil erosion.
Answers
Answer:
Soil erosion is the displacement of the upper layer of soil; it is a form of soil degradation. This natural process is caused by the dynamic activity of erosive agents, that is, water, ice, snow, air, plants, animals, and humans
Maintaining a healthy, perennial plant cover.
Mulching.
Planting a cover crop – such as winter rye in vegetable gardens. Includes annual grasses, small grains, legumes and other types of vegetation planted to provide a temporary vegetative cover. Cover crops are often tilled under serving also as a “green manure” crop.
Placing crushed stone, wood chips, and other similar materials in heavily used areas where vegetation is hard to establish and maintain.
Using other erosion controls that include the use of geo-textile materials or other methods such as sodding or hydroseeding that result in the establishment of permanent cover. These methods work well on steep slopes and heavy traffic areas. Contact your local landscape contractor or the RI Nursery and Landscape Association.
Addressing problem areas of that get lots of stormwater runoff. Solutions to these problem areas include redirecting stormwater and roof runoff to areas that can settle and dissipate water, such as a rain garden.

Soil erosion is the displacement of the upper layer of soil; it is a form of soil degradation. This natural process is caused by the dynamic activity of erosive agents, that is, water, ice, snow, air, plants, animals, and humans.
Rainfall, and the surface runoff which may result from rainfall, produces four main types of soil erosion: splash erosion, sheet erosion, rill erosion, and gully erosion. ... Sheet erosion is the transport of loosened soil particles by overland flow.
Erosion involved three processes:
- Detachment (from the ground).
- Transportation (via water or wind).
- Deposition.
The deposition is often in places we don't want the soil such as streams, lakes, reservoirs, or deltas.
