By definition, wind erosion involves the erosion, transportation and deposition of soil by the wind, according to Dictionary.com. Wind erosion is often worse during dust storms. Poor farming practices by humans combined with drought conditions such as occurred during the 1930s in the United States increase wind erosion.Continue Reading
Several factors worked together to increase wind erosion during the American Dust Bowl. Small gasoline tractors increased the amount of land a farmer was able to work. Plowing served to displace native, deep-rooted grasses that held the soil in place during typical drought conditions and high winds. When the drought of the 1930s struck, the plains were ripe for wind erosion. These storms affected over 100 million acres in Oklahoma and Texas. By the end of the 1930s, wind erosion removed over 75 percent of the topsoil in some areas. Erosion decreased the value of farm land and the profits of the farmer. The problems led to population declines in many counties.
Weathering and erosion work together to transform all land forms to sea level planes. However, volcanoes and uplifting land movements work against these two processes. Without the intervention of man, water works its way into the cracks of rocks and freezes to break smaller particles from the larger mass. Plants and animals aid the weathering process. As particles become small enough, water or wind picks them up and transports them to other areas.Learn more about Erosion & Weathering
Water, wind and tillage are the three greatest factors in erosion. Erosion occurs through soil detachment, movement and deposition, and pollutes nearby waterways, often creating an unstable base that can lead to a permanent loss in land.Full Answer >
The Schools of the Pacific Rainfall and Climate Experiment notes that coastal erosion occurs due to wave and current activity, storms, earthquakes, wind, tides and the shifting of tectonic plates. Coastal erosion is a mostly natural process; however, man-made structures such as piers and harbors can contribute to erosion due to restructuring of the natural environment.Full Answer >
The four agents of erosion are water, ice, wind and waves. Each of these agents is able to weather rocks, causing them to break apart after being worn down. Of the four agents of erosion, water is considered to be the most important and commonly occurring.Full Answer >
Wind erosion occurs in dry, bare areas when wind blows and moves dirt around. It damages crops by removing soil from the crops that need it and putting it somewhere else.Full Answer >
