Water erosion is the process by which soil and rock are worn away by the movement of water. This can occur through rainfall, rivers, or ocean waves, which can gradually remove material from the land. Over time, this can lead to the formation of valleys, canyons, and other geological features. There are different types of water erosion, including sheet erosion, rill erosion, and gully erosion. Each type varies in severity and the way it affects the landscape. Effective management practices, such as planting vegetation, can help reduce the impact of water erosion and protect soil health.
