Question
Why is soil erosion relatively less in dense forests as compared to barren, open fields?

Answer

In dense forests, the tree cover (canopy) prevents rainwater from, directly falling on the ground/soil. Also, the roots of vegetation bind the soil particles and hold them together. As a result, soil erosion is minimised. But in barren open fields, the soil is exposed to the failing rain. The soil particles become loose due to the impact of raindrops and the flow of water carries them away. The flowing water further erodes the soil surface aggravating erosion.
