Uncovered soil is exposed to raindrops which after collusion, the soil is weakened hence soil is easily eroded. Large raindrops will have a greater effect compared to small and gentle raindrops. Soil disturbance is greater when there is large raindrops and less when there is small and gentle raindrops. When the surface is covered, the soil is protected from direct force caused by the raindrops. Covering the surface significantly reduces soil disturbance. Slope affects the soil bexcause of the gravity, at the end of the experiment. During a storm, the soil rolls to the bottom of the slope. Covering the surface of a slope will reduce soil disturbance.
