How does afforestation prevent soil erosion?

Question

please give me a good answer that is to the point. its urgent

Answer 1

Afforestation is the process of establishing a forest on land that is not a forest, or has not been a forest for a long time by planting trees or their seeds.

Soil erosion is when the soil is blown away by the wind or washed away by the rain.

Roots of trees/plants hold the soil. Thus, when more trees are planted their roots don't allow the soil to be blown or washed away and prevent soil erosion.

Answer 2

Just go look up afforestation on wikipedia. Has more details etc.

By my own knowledge, afforestation is the meaning of planting a land that is not a forest, in other words, it means, planting trees so that soil erosion wont occur.
