  1. Name the 12 soil orders.
    • Gelisols
    • Histosols
    • Spodosols
    • Andisols
    • Oxisols
    • Vertisols
    • Aridisols
    • Ultisols
    • Mollisols
    • Alfisols
    • Inceptisols
    • Entisols
  2. Describe Gelisols


    Permafrost
  3. Describe Histosols


    Organic, wetland soils

    Differentiated based upon degree of decomposition of organic matter
  4. Describe Spodosols


    "Formed under acid forests"

    Acid litter causes eluviation of many compounds
  5. Describe Andisols


    Formed from volcanic ash, young soils
  6. Describe Oxisols


    Very old, thick sola, highly weathered

    Weathered B horizon
  7. Describe Vertisols


    Have expanding clays

    Self-churning soils due to expansion and contraction of clays
  8. Describe Aridisols


    Arid, can be highly developed

    Due to limited leaching, accumulation of various salts
  9. Describe Ultisols


    Brown soils formed under deciduous forest, low base saturation

    Thin, brown A horizon, must have an argillic horizon and/or a kandic horizon
  10. Describe Mollisols


    Dark soils formed under prairies, high base saturation

    Dark A horizon, B horizon can have a variety of endopedons
  11. Describe Alfisols


    Brown soils formed under deciduous forest, high base saturation

    Thin, brown colored A horizon, must have argillic horizon
  12. Describe Inceptisols


    Older than Entisols

    Weak B horizon
  13. Describe Entisols


    Young, thin sola, relatively underdeveloped soils

    Thin A horizon over parent material
