Answer 2

Soil erosion is partially caused by rain runoff washing away the soil. ... Plants also help absorb some of the water in the soil. These effects make it harder for water to wash the soil away. Plants also help reduce erosion in other ways, such as breaking the wind that might blow dry topsoil away.
