What is the result when excessive water is present in soil?

• A. Soil particles gain cohesion
• B. Soil particles float and lose coherence
• C. It creates a stable slope
• D. It promotes root growth

Answer: (B)

When excessive water is present in soil, the weight of the water can exceed the soil's ability to hold its particles together, causing soil particles to lose coherence and, in some cases, even float. This phenomenon is particularly relevant in saturated conditions where the soil becomes waterlogged. As water fills the pore spaces between soil particles, it reduces the friction and contact between them. As a result, the usual granular structure is disrupted, leading to a decrease in the soil's strength and stability. This situation can lead to various issues such as landslides or soil liquefaction, where the soil behaves more like a liquid than a solid due to the excessive saturation. Therefore, the correct answer accurately depicts the consequence of having too much water in the soil.
