What is vegetative cover primarily used for?

• A. Increasing soil salinity
• B. Protecting soil from erosion
• C. Improving air quality
• D. Enhancing visual appeal of landscapes

Answer: (B)

Vegetative cover plays a crucial role in protecting soil from erosion. When plants cover the soil surface, their roots help to anchor the soil in place, significantly reducing the impact of rainfall, wind, and surface runoff that can displace soil particles. The foliage and organic matter also dissipate the energy of raindrops hitting the ground, further preventing soil displacement. This natural protection is essential for maintaining soil health, preserving topsoil, and preventing sedimentation in nearby water bodies. While vegetative cover may have some impact on air quality and can enhance the visual appeal of landscapes, those are not its primary functions. Additionally, vegetative cover is designed to mitigate erosion rather than increase soil salinity, which is generally an undesirable condition for soil health.
