How does slope affect soil erosion
WebFlooding affects the environment by causing soil erosion, destruction of habitats for both plants and animals, contamination of water sources with pollutants, loss of biodiversity, and disruption to food chains. It also leads to economic losses and social impacts such as displacement of people from their homes.
