What is one effective method to stop water erosion?

• A. Building terraces
• B. Removing vegetation
• C. Increasing tillage
• D. Discing the field

Answer: (A)

Building terraces is an effective method to stop water erosion because it involves constructing level platforms on slopes. These terraces break the length of a slope, which reduces the speed of water runoff during rainstorms. By slowing down the water, terraces help to capture and hold moisture in the soil, allowing more time for it to penetrate the ground rather than running off and taking soil with it. This method not only prevents soil loss but also promotes better water retention and can enhance agricultural productivity. In contrast, removing vegetation contributes to erosion, as plants play a crucial role in anchoring soil with their root systems. Increasing tillage can disturb the soil structure and expose it to erosion since loose soil is more susceptible to being washed away. Discing the field, similarly, can create a loose soil surface which is more vulnerable to the impact of rainfall and subsequent water flow, leading to increased erosion. Therefore, building terraces is recognized as a proactive strategy for soil conservation and erosion control.
