Wind, water, ice and waves carry off soil particles and cause soil erosion. Although this is a natural process, human activities that disturb the surface of the earth increase the rate of soil erosion. Activities such as... More » Science Earth Science Soil

Soil erosion often causes the destruction of croplands, which in turn makes the prices of food soar and is the reason many individuals go hungry. According to a study by Cornell University, soil erodes away at 10 to 40 t... More »

Soil erosion negatively affects the environment by stunting the new growth of plant life due to removal of topsoil. Erosion greatly reduces the quality of the soil. More » Science Earth Science Soil

By definition, soil salinization is "the process by which a nonsaline soil becomes saline, as by the irrigation of land with brackish water," according to The dissolved salts in irrigation water are the p... More »

Wind causes erosion in one of three ways: suspension, saltation or surface creep. There are many problems that arise from wind erosion, including air pollution, soil loss and dryness. Soil tillage, crop barriers and crop... More »

Wind erosion happens when pieces of the Earth are worn away by strong winds over time, and water erosion happens when moving water such as ocean waves wear away rock instead of seeping into the ground. Water is a more po... More »

Contour plowing conserves soil by following the lay of the land and creating ridges that form a water break to prevent soil erosion. Furrows that do not follow the lay of the land cause rapid runoff during rainfall by fo... More »
