Explanation-Erosion

Erosion is the process where rocks and soil is moved from one place to another.
Wind, rain, livestock and speedboats all cause erosion.
Wind moves topsoil and transfers it to other areas. Rain washes soil downhill on slopes. Livestock kills vegetation and the soil cannot be held. Speedboats cause waves which causes landslides.
We can plough right away, rotate stock and plant trees to prevent erosion.
