Man has cut too many jungles, has grazed the grasses excessively, and ploughed the land too often. Rainstorm produces four major types of soil erosion including rill erosion, gully erosion, sheet erosion, and splash erosion. The outward and downward movements of sediments and rocks on slanting or slope surfaces due to gravitational pull qualify as an important aspect of the erosion process. Geologists estimate that 70 percent of soil erosion is caused by human activities like excessive construction, agriculture, surface mining and forestry. Farmers remove native vegetation and then plow the land to plant new seeds. Causes of Soil Erosion: Various agents, like wind, water, deforestation, overgrazing by cattle, and etc., cause soil erosion. Some of the dust particles may contain harmful and toxic particles such as petroleum and pesticides that can pose a severe health hazard when inhaled or ingested. Grazing animals can cause erosion if they are allowed to overgraze and remove too much or all of the vegetation in a pasture. Since Europeans settled in North America, about one-third of the topsoil in the area that is now the United States has eroded away. Grazing animals (FigureÂ 2)Â wander over large areas of pasture or natural grasslands eating grasses and shrubs. This erosive activity is evident in most rivers or streams especially during heavy rainfall and rapid river channel movement. How do Rainbows Form? Figure 4. http://www.ck12.org/earth-science/Soil-Erosion/lesson/Soil-Erosion-HS-ES/?referrer=featured_content. Soil erosion is, thus, more common in desert or Barren land. A land is overgrazed if too many animals are living there. What are some human activities that increase the likelihood that soil will be eroded? The process is triggered by various phenomena taking place on the planet, ranging from slow-moving ice bodies in the glacial mountains, to landslides caused by earthquakes. Erosion by Water Water is the main cause of erosion on Earth. The root structure of trees hold the soil in one place. Soil erosion is more likely where the ground has been disturbed by agriculture, grazing animals, logging, mining, construction, and recreational activities. This means most of the environmental problems the world face today arises from soil erosion. Farming activities such as tillage also significantly contribute to soil erosion. Erosion, physical process in which soil, rock, and other surface material are removed from one location and transported to another. Soil erosion is a continuous process that occurs either slowly or at an alarming rate. The various factors of soil erosion are: 1. Here are few of the major causes of soil erosion. Sheet erosion affects a whole area, when water or the wind act like a broom to clear out the topsoil. Once you know why your soil is eroding, you can take the steps to resolve the issue and pacify your neighbor. It happens in the place where soil is not covered by plants. It also sends soil-laden water downstream, which can create heavy layers of sediment that prevent streams and … Luxury Landscape Supply explains the four common causes of soil erosion below. Some Other Causes of Soil Erosion: 1. The wearing away of the topsoil is driven by erosion agents including the natural physical forces of wind and water, each contributing a substantial quantity of soil loss annually. Wind is also a leading cause of soil erosion because wind can pick up soil and blow it far away. This usually leads to loss of biodiversity, alteration of ecosystems, land degradation, and huge economic losses. Water ways may also be blocked, and it may affect water quality. The wind picks up the loose soil particles with its natural force and carries them away to far lands, leaving the soil sculptured and denudated. The type of soil moreover affects the potentiality of the occurrence of soil erosion. Completed construction can also contribute to erosion (Figure 6). Fine soil is blown away by wind. Soil erosion is a process that involves the wearing away of the topsoil. In some arid and semiarid areas, wind can be the cause of soil erosion too. Soil erosion is a major driver of desertification. (Albinism), Can Squirrels Eat Almonds? Agriculture is probably the most significant activity that accelerates soil erosion because of the amount of land that is farmed and how much farming practices disturb the ground (FigureÂ 1). They also churn up the ground with their hooves.
