Which of the following will retain the greatest amount of water?
Answer Details
Clay will retain the greatest amount of water compared to the other options. This is because clay has smaller particles than sand or silt, which allows it to hold more water due to the greater surface area available for water molecules to bond to. Clay soils can retain water for longer periods of time, which can be beneficial for plant growth during dry periods. In contrast, sandy soils have larger particles with fewer surfaces available for water bonding, causing water to drain away more quickly. Loam soils are a mixture of sand, silt, and clay, and can have varying water retention capacities depending on the ratio of the soil components.
