Detailed explanation-1: -Soil erosion is the washing away of soil by wind or water. The roots of a plant hold the soil firmly. Because of this, soil cannot easily be washed or blown away. So, plants prevent soil erosion.

Detailed explanation-2: -Plant roots hold the soil in position and prevent it from being blown or washed away. Plants break the impact of a raindrop before it hits the soil, reducing the soil’s ability to erode.

Detailed explanation-3: -Trees reduce the effect of erosive forces using their root systems and foliage. Trees have thick root systems that branch into fine filaments and create a network. This network of root systems help stabilize the soil around the tree and hold it in place.

Detailed explanation-4: -Trees prevent soil erosion. The roots of trees hold the soil tight and prevents washing away of the soil.

Detailed explanation-5: -Trees and woody vegetation do good things for agricultural land. They reduce soil erosion and provide habitat for pollinators. When planted along waterways as riparian buffers, they reduce run-off of nutrients and soil sediment in-stream.
