Terracing on hillside is most effective for which land type?

• A. Flat farmland
• B. Steep slopes
• C. Desert plains
• D. Wetlands

Answer: (B)

Terracing on hillside is most effective because it directly tackles the problems that come with slope: rapid water runoff, soil erosion, and nutrient loss. By turning a slope into a series of level steps, each terrace slows the flow of water, allows more time for infiltration, and keeps soil in place. That creates stable, flat planting areas where crops can establish roots and receive more consistent moisture and nutrients.

On flat farmland, terraces aren’t needed since the ground is already level. Desert plains are typically very flat or have limited and irregular rainfall, so building terraces wouldn’t provide the same erosion-control benefits and would add unnecessary cost. Wetlands are saturated areas where the priority is managing water levels and conservation, not creating stepped fields, so terraces would disturb natural hydrology.
