Which of the following best explains why wind action is more predominant in Arid regions than in Humid regions?

  1. Loose surface materials and the absence of vegetation cover ✓
  2. Excessively high temperature during the day and night
  3. Insufficient and unreliable rainfall
  4. Lack of surface drainage and the presence of strong winds
Explanation

In deserts, there are no plants to hold the soil in place. The ground is covered with loose sand and dust.

Wind can easily pick up and carry these loose materials. In humid areas, plants and wet soil stop the wind.

Without vegetation, desert winds shape the land through erosion and sand movement.
