Final answer:
Wind erosion is more effective in arid regions because these areas have less vegetation cover and the soil is drier, making it easier for wind to pick up and move particles. Moreover, wind intensity and frequency in arid regions are commonly higher. While wind erosion can also occur in humid regions, the effect is mitigated due to the dampness and higher vegetation coverage.
Step-by-step explanation:
Wind erosion is relatively more effective in arid regions than in humid areas due to several factors. One primary reason is that arid regions typically have less vegetation cover, which allows for the wind erosion to more readily pick up and move soil particles. Furthermore, the dryness of arid regions means the soil is less cohesive and more easily eroded by wind than damp soil found in humid regions.
More frequent and intense winds also contribute to the increased wind erosion rate in these areas. Without the resistance from plants and the damp soil, the wind moves across the land surface with ease, creating sand dunes and other wind shaped landforms. However, this does not mean that wind erosion does not occur in humid areas. The impact is lesser due to the dampness and more considerable vegetation cover.
