INDIAN GEOGRAPHY

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: -Tree root systems help reduce erosion by holding soil in place. Even after being cut, the roots attached to the stump help stabilize soil for years. Reducing risk of landslides.

Detailed explanation-3: -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.

Detailed explanation-4: -Roots prevent soil erosion by acting as an anchor for soil, keeping it in place rather than allowing it to be swept away. While an erosive force, like a heavy rainfall, can wash away soil quantities, roots have such a firm hold in soil that they cannot be washed away, and they maintain the soil they are attached to.

Detailed explanation-5: -Roots of trees help to prevent (soil erosion) and control the (natural calamities). REASON: Since roots of trees go underneath the soil they hold the soil tightly so that water or wind cannot erode it.
