Emissions - Interesting Facts About Soil Erosion
Do you know about - Interesting Facts About Soil Erosion
Emissions! Again, for I know. Ready to share new things that are useful. You and your friends.Soil erosion occurs when soil is blown away by wind or washed away by rain. Each of these agents contributes a significant amount towards soil loss each year. Soil erosion may be a slow and unnoticeable process or it may occur at an alarming rate causing serious loss of topsoil.
What I said. It shouldn't be the conclusion that the true about Emissions. You read this article for info on that wish to know is Emissions.How is Interesting Facts About Soil Erosion
We had a good read. For the benefit of yourself. Be sure to read to the end. I want you to get good knowledge from Emissions.Wind erosion occurs in areas with little or no vegetation. It takes one of two forms. It either happens when small particles are picked up by the wind and deposited in another region, or when these particles collide against other surfaces and cause erosion by abrasion. Speed and duration of wind also have a direct effect on the amount of soil erosion.
Rainfall and runoff are the most important direct drivers of severe soil erosion by water. If the force applied to the soil is greater than the resistance of the soil, then particles with detach and move away in either splash or surface flows. As the force increases, so does the rate of detachment.
The main impact of soil erosion is reduction of soil quality that results from the loss of the nutrient-rich upper layers of soil., and the reduced water -holding capacity of the eroded soil. In addition to this, soil that is transported to other regions can create "off-site" problems like silting up of dams, disruption of eco systems, and contamination of drinking water.
Soil erosion can be prevented in different ways. Increase in vegetation causes the roots of plants to interlock in such a way as to bind the soil particles. Slopes are also more susceptible to losing soil because of the combined effects of gravity and running water. Planting trees and reforestation of these slopes will serve to arrest erosion. Another effective option is terracing where fields are built at right angles to the slope.
