Question
Which of the following statements is/are true about soil
erosion? Statement A: Rill erosion is a more severe form of erosion compared to gully erosion. Statement B: Vegetative cover can help reduce soil erosion by minimizing the impact of rainfall. Statement C: Wind erosion is more common in moist and humid regions.Solution
Gully erosion is a more severe form of erosion compared to rill erosion. Gully erosion occurs when concentrated water flow creates deep channels or gullies, whereas rill erosion involves the formation of small channels on the soil surface. Vegetative cover, such as plants and grasses, plays a vital role in reducing soil erosion. The roots of plants help bind the soil particles together, improving soil structure and stability. Wind erosion is more common in dry and arid regions where there is insufficient vegetative cover and strong winds. In moist and humid regions, the presence of vegetation and higher moisture levels generally mitigate wind erosion.
