What effect does planting vegetation have on soil erosion?

Planting vegetation significantly reduces soil erosion, which is why this option is the correct one. Vegetation plays a crucial role in stabilizing the soil through several mechanisms.

The roots of plants bind the soil particles together, making it more difficult for wind and water to dislodge them. This binding effect creates a stronger structure within the soil, which can withstand erosive forces. Furthermore, the presence of plants decreases the speed of rainwater as it hits the ground, which reduces the potential for runoff that might carry soil away. The canopy of leaves slows down rainfall, allowing more water to infiltrate the ground instead of running off.

Additionally, vegetation enhances soil health by contributing organic matter through decaying leaves and roots, which further improves soil structure and its ability to retain moisture. This capacity for moisture retention also reduces the chances of erosion, as drier soils are more prone to being washed or blown away.

By promoting these benefits, planting vegetation serves as an effective strategy for soil conservation and maintaining the integrity of land in various ecological contexts.
