Question
Explain four ways in which vegetation prevents soil erosion.
Answer
- The leaf cover helps to reduce the force of raindrops which would otherwise loosen and remove soil particles if the force is not checked.
- The rate of infiltration of rainwater into the soil is increased by vegetation cover thus reducing surface runoff.
- Plant cover breaks the force of wind at the ground level and reduces the transportation of soil particles/ reduces the evaporation which would dry and loosen the soil
