what is soil erosion
Answers
Answer:
Soil erosion is the displacement of the upper layer of soil; it is a form of soil degradation. This natural process is caused by the dynamic activity of erosive agents, that is, water, ice (glaciers), snow, air (wind), plants, animals, and humans. In accordance with these agents, erosion is sometimes divided into water erosion, glacial erosion, snow erosion, wind (aeolean) erosion, zoogenic erosion and anthropogenic erosion such as tillage erosion.[1] Soil erosion may be a slow process that continues relatively unnoticed, or it may occur at an alarming rate causing a serious loss of topsoil. The loss of soil from farmland may be reflected in reduced crop production potential, lower surface water quality, and damaged drainage networks. Soil erosion could also cause sinkholes.
Soil erosion is commonly characterised as the loosening or washing away of soil particles in the oceans, rivers, valleys, streams, or faraway areas.
Explanation:
- Erosion occurs and worsens as a result of human activities such as deforestation and agriculture. Erosion is a continuous process that can happen at a slow or rapid pace. It causes topsoil erosion, ecological degradation, soil collapse, and other problems.
- Soil erosion is mostly caused by heavy rainstorms.
- The lower layer is disturbed by agricultural activity. The area is ploughed to sow new seeds after the trees are cleared.
- The grazing animals prey on the grasses and deplete the land's vegetation.
- The erosion of soil occurs as a result of the development of roads and structures.
