Which soil type is characterized by high permeability?

The correct answer is sandy soils, which are characterized by high permeability due to their larger particle size and loose structure. This allows water to move through the soil more easily compared to other soil types. Sandy soils typically have good drainage because the spaces between the sand particles are larger, facilitating quick water movement and reducing the likelihood of waterlogging.

In contrast, clay soils have very small particles and compact structure, which restricts movement and leads to lower permeability. Silt soils, while they have larger particles than clay, do not drain as quickly as sandy soils due to their smooth texture and smaller particle size. Peaty soils, containing a high amount of organic matter, also tend to retain moisture and have lower permeability. Thus, sandy soils are the only type in the given choices that allow for rapid water infiltration and drainage.
