What role do tree roots play in land changes?

Tree roots play a crucial role in stabilizing soil and preventing erosion. When trees grow, their roots penetrate the soil, creating a network that helps bind the soil particles together. This interconnected system allows the soil to maintain its structure and resist being washed or blown away by wind and water. By keeping the soil in place, tree roots help to maintain the land's integrity and reduce the risk of erosion, especially on slopes or areas susceptible to heavy rainfall.

In contrast, the other options reflect misunderstandings about the role of tree roots. While they do not cause erosion or speed up weathering, tree roots can combat these processes effectively. The assertion that tree roots have no effect on soil disregards their significant contribution to soil stability and ecosystem health. Therefore, recognizing the importance of tree roots in stabilizing soil highlights their vital role in land management and environmental conservation.
