Soil stability refers to the ability of soil to maintain its structure and resist erosion or displacement. It is influenced by factors such as soil composition, moisture content, and vegetation. Stable soil supports plant growth and prevents landslides, making it essential for agriculture and construction. When soil is stable, it can effectively absorb water and nutrients, promoting healthy ecosystems. Conversely, unstable soil can lead to problems like soil erosion, which removes the top layer of fertile soil, and landslides, which can cause significant damage to infrastructure and natural habitats.
