how do plants prevent soil erosion

Answer 1

ecomerge.blogspot.comPlants provide protective cover on the land and prevent soil erosion for the following reasons: Plants slow down water as it flows over the land and this allows much of the rain to soak into the ground. Plant roots hold the soil in position and prevent it from being blown or washed away.
