    1) Fill in the blanks regarding characteristic properties of soil colloids.

    Soil Colloid Type

    Name one defining characteristic of this colloid

    Where in the soil profile will these colloids dominate? What soil order would contain a large amount of these colloids?
    Crystalline silicate clay (1:1)
    Crystalline silicate clay (2:1)
    Noncrystalline silicate clay
    Fe and Al Oxides
    Humus

    2) Describe the major difference between a 1:1 silicate clay and a 2:1 silicate clay.
