DENDROLOGY

Detailed explanation-1: -You can see silt particles only through a microscope. Silt feels like flour. It forms into a ball that easily breaks apart. If you squeeze it between your thumb and fingers, it will not form ribbons.

Detailed explanation-2: -Silt-sized particles, normally 0.002-0.05 mm in size, and cannot be seen with the naked eye, i.e. some form of magnifier is needed. Clay-sized particles, less than 0.002 mm in size. It is beyond the capacity of the naked eye to identify individual clay particles, and a strong microscope is needed to do so.

Detailed explanation-3: -Dry soils arranged from fastest to slowest permeabilities are gravel, potting soil, sand, silt, and clay. Wet soils arranged from fastest to slowest permeabilities are gravel, potting soil, sand, silt, and clay. Diffusion arranged from greatest to least is gravel, potting soil, silt, sand, and clay.
