EVERYDAY SCIENCE

Detailed explanation-1: -The roots of the plants bind the soil together, and interweave with other roots, forming a more solid mass that is less susceptible to both water and wind erosion. The removal of vegetation increases the rate of surface erosion.

Detailed explanation-2: -First, plant roots hold sediment in place, helping to stabilize the areas where they are planted. Second, by absorbing water, breaking the impact of raindrops or wave-splash, and physically slowing the speed and diffusing the flow of overland runoff, plants reduce runoff erosion.

Detailed explanation-3: -Trees prevent soil erosion. The roots of trees hold the soil tight and prevents washing away of the soil.

Detailed explanation-4: -With increasing silt content increasing, soils are more apt to undergo erosion (Zhang et al., 2001). According to the above authors, vegetation plays an important role in water and soil erosion control. Vegetation cover can reduce the kinetic energy of raindrops.

Detailed explanation-5: -Plant and residue cover protects the soil from rain-splash and slows the movement of surface runoff thereby increasing infiltration. Similarly, vegetation reduces the wind velocity, thereby mitigating the dispersion of soil and sediments.
