OBJECTIVE FORESTRY

Detailed explanation-1: -Roots of trees hold the soil particles and prevent their loss. When trees are cut on a large scale land becomes barren. This results in the loss of upper soil layer due to heavy wind or flowing water leading to soil erosion. Hence afforestation prevents soil erosion.

Detailed explanation-2: -Answer: Vegetation absorbs energy so it lessens the impact when precipitation hits the ground. However, the tree roots are what stabilize the soil and tie the soil layers together to prevent soil displacement. They hold the soil in position to prevent it from being blown or washed away.

Detailed explanation-3: -Summary: The tiny hairs found on plant roots play a pivotal role in helping reduce soil erosion, a new study has found. The research provides compelling evidence that when root hairs interact with the surrounding soil they reduce soil erosion and increase soil cohesion by binding soil particles.
