Detailed explanation-1: -Dry soils arranged from fastest to slowest permeabilities are gravel, potting soil, sand, silt, and clay.

Detailed explanation-2: -Gravel and sand are both porous and permeable, making them good aquifer materials. Gravel has the highest permeability.

Detailed explanation-3: -Sandy soils are known to have high permeability, which results in high infiltration rates and good drainage. Clay textured soils have small pore spaces that cause water to drain slowly through the soil. Clay soils are known to have low permeability, which results in low infiltration rates and poor drainage.

Detailed explanation-4: -Usually, the finer the soil texture, the slower the permeability. Clay is impermeable, or at least it has a very low permeability. The grains in clay are so fine that the spaces between the grains are extremely small. This makes it difficult for water to squeeze through, so water is more likely to simply run off.

Detailed explanation-5: -Excessively permeable soils are those having high amount of sand exceeding 70 percent. Due to this, the soils are inert and unable to retain nutrient and water.
