Answer: B. Tree roots act like "nets" that hold the soil together and prevent it from being washed away by rain.

Answer: (B)
Simple Explanation: Roots are the "anchor" of the earth. When trees are gone, there is nothing to hold the dirt in place, so the good, nutritious topsoil gets washed away during the first heavy rain.
