Soils and Rocks

Twelve Soil Orders:

1. Gelisols-have permafrost within 100 cm of the soil surface
2. Histosols-consists primarily of organic materials 3.
Spodosols-soils with mixtures of organic matter and aluminum
4. Andisols-soils dominated by short-ranger-order minerals

5. Oxisols-mixtures of quartz, kaolin, free oxides, and organic matter found in tropical and subtropical environments

6. Vertisols-soils with a lot of expanding clay

7. Aridisols- CaCO3 containing soils of arid environments with subsurface horizon development. No water for plants

8. Ultisols-contains translocated silicate clay and few bases

9. Mollisols- base rich

10. Alfisols-base saturation of 35 percent or greater and have a argillic horizon

11. Inceptisols-soils of humid or subhumid regions with that have altered horizons that have lost bases but retain weatherable materias

12. Entisols-soils with little or no morphological development
