Soil erosion is the process by which the top layers of soil are removed or displaced by wind, water or ice. The loss of fertile soil can result in serious consequences for humans and other organisms in many ways. Soil erosion also causes serious damage to houses, bridges, roads and other forms of infrastructure. Soil conservation is a method of trying to stop soil erosion by slowing down the rate at which the soil is denuded. In this post we are going to discuss about Soil Erosion and Soil Conservation MCQs and Answers. We also post the most important post to you Resources And Development Class 10 MCQ and Answer that will help you the most.
