Which of the following statements about sand is true?

The statement about sand that is true is that it allows for rapid water drainage. Sand particles are larger and have larger pore spaces compared to finer soil particles like silt and clay. This structure permits water to flow through sand quickly, making it an excellent choice for drainage in various applications, such as landscaping and construction projects. In situations where quick drainage is desired, such as in areas prone to flooding or where plant roots require well-aerated soil, sand is highly effective.

In contrast, the other statements about sand do not hold true. Sand is not the smallest particle found in soil, as that designation goes to clay particles. Additionally, sand typically has a low nutrient content compared to other soil types, such as loam, which contains a balanced mixture of sand, silt, and clay along with organic material that enriches nutrient availability. Finally, sand does not retain moisture better than clay; in fact, clay has a much higher capacity to hold moisture due to its small particle size and compact structure, making it excellent for retaining water.
