Which of the following is a factor contributing to soil erosion?

Water runoff is a significant factor contributing to soil erosion as it involves the movement of water across the land's surface, especially during rainfall events. When water flows over the soil, it can dislodge and transport soil particles, leading to the removal of topsoil and degradation of soil structure. This process can be exacerbated by factors such as the slope of the land, intensity and duration of rainfall, and lack of vegetation cover, making it a critical concern in agricultural practices.

In contrast, practices like crop rotation, organic fertilization, and soil enrichment actively contribute to soil conservation and health, making them beneficial in preventing erosion. Crop rotation helps maintain soil structure and fertility, organic fertilization enhances soil organic matter, and soil enrichment practices improve soil health and resilience, further mitigating the risks associated with soil erosion.
