Countries all over the world are battling with worrisome sight of deepening gullies crisscrossing the landscape and barren fields stripped of the fertile topsoil. The effects of soil erosion go beyond the loss of fertile land. This leads to plants dying which means that all of the roots disappear and their is nothing to hold the soil in place. Wind erosion damages the soil by physically removing the most fertile part, lowering water-holding capacity, degrading soil structure, and increasing soil variability across a field, resulting in reduced crop production. Several industries are affected by the loss of soil quality or the degradation of crops and their yields. Soil Erosion affects the people, plants, and animals of Africa by causing widespread hunger throughout the continent. It has led to increased pollution and sedimentation in streams and rivers, clogging these waterways and causing declines in fish and other species.And degraded lands are also often less able to hold onto water, which can worsen flooding. It also causes plant damage from abrasion, blowouts, and deposition. Secondly, how does erosion affect landforms? Probably the most noticeable effect of soil erosion is land degradation. How topography affect soil erosion Contents - Previous - NextThe topographical factor Although slope has a strong influence on erosion, the presence of erosion and heavy runoff on gentle slopes (2% in the Sahel or in the European highlands) suggests that this phenomenon can occur without the need for steep slopes: rain action is .

Landforms are usually made up of rocks, soil, mud, clay, minerals, and other debris. When land degrades, it destroys habitats and decreases the amount . Sand dunes are landforms that are created by the wind agent of erosion. Science Help n.d. This can be in sediment traps, along . Eroded soil, which can contain nutrients, fertilisers and herbicides or pesticides, can be deposited where there is a reduction in the slope of the land. It has led to increased pollution and sedimentation in streams and rivers, clogging these waterways and causing declines in fish and other species. Soil erosion occurs naturally by wind or harsh climatic conditions but human activities include overgrazing, overcropping and deforestation. The movement of these sediments is caused by weathering and erosion. In the erosion process, the particles of soil break down. In case of sheet erosion the top soil of a large area moves off over a period of time. In comparison, Asia and Europe tally $3.5 and $4.5 billion respectively. Physical forces in the desert that break down rocks include the daily heating and cooling of rocks on the surface, expansion of plant root in cracks, the freezing and melting of ice in cracks, and exposure to wind and precipitation (particularly during . Prof. A.Balasubramanian. Weathering and erosion can cause changes to the shape, size, and texture of different landforms (such as mountains, riverbeds, beaches, etc). A. The ice erodes the land surface and carries the broken rocks and soil debris far from their original places, resulting in some interesting glacial landforms. Meat and Dairy: Chicken, cattle, and swine are all . U2: Erosion is one of the forces that causes landforms to change . Intensive agricultural land use can have detrimental effects on landscape properties, greatly accelerating soil erosion, with consequent fertility loss and reduced agricultural potential. Soil erosion is the carrying away of the top soil layer by ice, water and wind. Wind- it is an agent in which it continuously carries away the loose particles or rock and soil to another place to where it deposits the dust in wide areas where the hills of sands are formed. Eroded soil, which can contain nutrients, fertilisers and herbicides or pesticides, can be deposited where there is a reduction in the slope of the land.
