What role does vegetation play in controlling wind velocity during erosion?

Vegetation plays a crucial role in controlling wind velocity, particularly in areas susceptible to erosion. When plants, such as grasses and shrubs, are present, they act as physical barriers that obstruct wind flow. This interference reduces the wind's speed close to the ground, which, in turn, minimizes the potential for erosion caused by wind. The roots of the plants also help stabilize the soil, further preventing erosion by maintaining soil structure and integrity.

When vegetation is absent, wind can move freely and with greater intensity, leading to increased erosion and the loss of topsoil. Hence, the presence of vegetation actively reduces wind velocity, making it beneficial for soil conservation and protecting landscapes from wind-induced erosion.
