What type of soil would likely be characterized by a lower water retention rate?

Sandy soil is characterized by larger particles and a loosely packed structure, which allows for greater drainage and reduced water retention. This type of soil has significant spaces between the particles, leading to quick water movement through the soil profile. As a result, sandy soils typically retain less moisture compared to other soil types because water passes through them rapidly.

In contrast, clay soil has very fine particles that are tightly packed, leading to higher water retention rates. Loam soil, a balanced mixture of sand, silt, and clay, retains a moderate amount of water, making it ideal for many plants. Peaty soil contains a high amount of organic material and moisture, providing it with excellent water retention capabilities. Thus, sandy soil stands out as the type with the lowest water retention rate among the provided choices.
