Soil erosion, or degradation, is prevented using erosion control methods. The types of control methods used vary depending on several factors, such as the depth and severity of soil erosion that has occurred on a propert... More »

Soil erosion solutions include increasing ground cover, mulching, preventing tillage and building structures. The type of solution depends on the area in which the erosion occurs. More »

Depending on the chemicals in the soil, the pH of water passing through it increases, decreases or remain the same. In areas where water passes through soil containing limestone, dissolving the calcium carbonate in water... More »

Soil degradation is the decline in soil quality caused by its improper use, usually for agricultural, pastural, industrial or urban purposes. Deserts are examples of extremely degraded soil areas, while the southern Unit... 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 »

Residual soil is the accumulation of soil caused by the erosion of underlying bedrock, while transported soil is soil deposited into new regions after erosion. Both types of soil are formed from the chemical and mechanic... More » Science Earth Science Soil

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
