There are three forces that cause what is commonly called soil erosion: Air {wind), water, and chemical leaching. Air moves sand and to a lesser degree silt. Anything that modifies the wind direction and force will decrease wind erosion. Some examples are grass, "breaking up surface" with a cultivar to add turbulence so that the wind will not move the soil as well, or planting crops, trees or wind breaks. Water erosion also can be affected by adding dams, plants (roots,) or terracing. Leaching is where the chemical elements of soil dissolve in the water and are carried by gravity to a lower strata, then when water evaporates; remains in the new location. This process is called weathering. The best way to change this is to make small water troughs (ponds or lakes) that run laterally across the strata to catch the water (called berms.) These could be anchored by fruit trees to reclaim the elements in the food cycle.

∙ 14y agoit is protected by planting crops and grass......so its mostly just planting plants will help because plant roots grab hold of the soil and the things under it so when ersion comes close to happening the roots grip and nothing get shaken around!
hopefully ive helped...im srry if i didnt only in fifth !

Why is contour plowing?
used to prevent soil erosion and conserve rainfall.
Why did the dust bowl lead to the adoption of methods of sving soil?
The dust bowl helped people appreciate the value of soil
How contour plowing prevent soil erosion?
It slows the water from rain as it comes down the terraced area, thus preventing erosion. Terracing helps to prevent erosion because it slows rain water as it runs down the terraced area.
What effective way to fight desertification?
Reforestation addresses the root causes of desertification. Techniques focus on three aspects: provisioning of water, fixation of the soil, and hyper-fertilizing the soil. Contour trenches are 150m long, 1m deep trenches in the soil, parallel to the height lines of the landscape to prevent erosion caused by the flow of water. Stone walls around the trenches prevent them from filling in. Sand fences can also be used to control drifting of soil and sand erosion. Fixating the soil is accomplished by the use of shelter belts, woodlots and windbreaks. Zaï or tillage are used to enable crops to grow in consolidated soils (like clay). Enriching the soil and restoration of its fertility is often done by plants. Of these, the Leguminous plants, which extract nitrogen from the air and fix it in the soil, and food crops/trees such as grains, barley, beans and dates are the most important.
Erosion is the invasion of nonnative weeds on natural soil true or false?
False, erosion is the gradual wearing down,wearing away of something. In nature it refers to such phenomena as the destructive effect of rivers on their banks, tides on shores, wind and weather on mountains The word is used in metaphor and analogy too. Some members of the Augusta Golf Club regard the admission of women as an erosion of the Club's charter principles
What is the importance of contour plowing?
to conserve the soil and protect it from erosion and weathering.The science behind contour farming is that the topsoil will not be as susceptible to erosion from wind and water when plowed in contours that follow the land elevations. The Dust Bowl in the 1930's was made worse by the straight line plowing methods used at the time.
How can word erosion be used in a sentence?
The ground had suffered from years of soil erosion.
What technology is used in coastal erosion?
No technology is used in costal erosion, it is a natural process from several different methods.
Why is plows used?
used to prevent soil erosion and conserve rainfall.
Why is plow used?
used to prevent soil erosion and conserve rainfall.
What is the technology used to prevent soil erosion?
There really is no special technology that will prevent soil erosion, rather modes of practice. No-till farming is one such practice that is designed to prevent or minimize soil erosion.
What are four farming methods used to prevent erosion?
shooti
Which of soil conservation methods is least used in NJ?
Windbreaks
What are the latest technology used to prevent soil erosion?
surf in the internet
Why is contour plowing?

Why does drip irrigation prevent soil erosion?
The problem of surface soil erosion associated only during surface application method.Soil erosion are practically absent in this method.Because pipes are used to supply water to the fields.
Terraces are used to farm areas in what kind of geography?
To prevent Soil Erosion
