Test: Land Soil Water Natural And Wildlife Resources- 2 - Class 8 MCQ

Few soil conservation methods include:

i) Graduated terrace steps which are commonly used for farming on hilly or mountainous terrain. Terraced fields decrease both erosion and surface runoff.

ii) Windbreaks: Row of trees or a fence, wall, or screen that provides shelter or soil protection from the wind.

iii) Conservation tillage is a method of preparing soil from getting eroded. This technique involves leaving the previous year’s crop residues until the next crop is planted.

An international convention CITES has been established that lists several species of animals and birds in which trade is prohibited.

Rocks are piled up to slow down the flow of water. This prevents gullies and further soil loss.

• Windscreens (like rows of trees or shrubs) help reduce wind speed, which prevents wind erosion of the soil.
• Good plant covers (like grass, crops, or trees) protect soil from water erosion and also help in binding the soil with their roots.
