Explanation:

Consequences of soil erosion

Soil erosion removes the nutrient-rich topsoil layer, which is essential for plant growth, leading to reduced agricultural productivity and degraded terrestrial habitats.

Methods to prevent soil erosion

Vegetation cover, such as planting cover crops or trees, stabilizes the soil structure with root systems and shields the surface from wind and water impact.
