Why barren hill slope gets eroded easily as compared to a hill slope covered with vegetation?

Barren hill slopes are more susceptible to erosion because they lack vegetation, which helps anchor the soil in place with root systems. Without this protective cover, raindrops can directly impact the soil, increasing runoff and leading to greater soil displacement. Additionally, vegetation helps to absorb water and reduce the speed of runoff, further mitigating erosion. In contrast, vegetated slopes are better at retaining soil and moisture, making them more resilient against erosive forces.
