See our User Agreement and Privacy Policy. Humans obtain more than 99.7% of their food (calories) from the land and less than 0.3% from the oceans and other aquatic ecosystems. In other words, it reduces the ability of rain water/wind to detach the soil particles and transport the eroded soil mass or sediments.

Formation of Soil Soil is formed by the process of weathering Weathering is the process of breaking down of rocks or other material into smaller particles due to long exposure to atmosphere Weathering agents are : 1) wind 2) water 3) Temperature 4) pressure Soil erosion is the washing or blowing away (by wind or water) of the top layer of soil (dirt).Erosion also leaves large holes in the earth, which can weaken buildings and even cause them to collapse.

The term soil erosion covers a wide range of physical and chemical actions, such as removal of soluble matters, chemical changes, disintegration by frost or by rapid changes of temperature, attrition by dust charged wind, scouring by silt laden currents, alternate impact and succession by storm waves, landslides and so on – Fox (1950).

Turf, ornamental grass, and low, spreading shrubs work best since they cover the soil completely. IMPORTANCE OF PLANTS IN CONTROLLING SOIL EROSION Plants provide protective cover on the land and prevent soil erosion for the following reasons: Plants slow down water as it flows over the land (runoff) and this allows much of the rain to soak into the ground Plant roots hold the soil in position and prevent it from being washed away Plants break the impact of a raindrop before it hits the … released/dropped by their agent of erosion –Process of erosion stops: •when the moving particles fall out of the transporting medium and settle on a surface –Speed of the medium slows or the resistance of the particles increases, the balance changes and causes deposition –Speed can be reduced by large rocks, hills, vegetation, etc. Summary 10.

In such cases the top soil is washed away. Water erosion can be caused by both natural precipitation and applied irrigation. Home | Food and Agriculture Organization of the United Nations The rate of erosion on a construction site varies with site conditions and soil types but is typically 100 to 200 tons per acre and may be as high as 500 tons per acre. It is based on the Jeopardy TV show and part of the SOIL AND EROSION UNIT There are 30 questions and they progressively get harder as the game moves along.
