  1. 1. Designating the inorganic nature of a substance.
  2. 4. The group of processes whereby earthy or rock material is worn away, loosened, or dissolved and removed from any part of the earth’s surface.
  3. 5. An organism so small that it cannot be seen clearly without the use of a microscope; a microscopic or submicroscopic organism.
  4. 6. A group of textural classes in which the particles are finer than gravel but coarser than silt, ranging in size from 2.00 to 0.5 millimeters in diameter.
  5. 7. Process of soil deposited due to erosion.
  6. 11. To gather or collect.
  7. 13. Unweathered hard rock that lies directly beneath the soil layers or beneath superficial geological deposits, such as glacial drift.
  8. 14. Accumulation of water-worn pebbles larger than two millimeters in diameter.
  9. 17. The artificial application of water to soil for the purpose of increasing plant production.
  10. 19. Refers to the extent of voids or openings in the soil that exist between soil particles and soil peds or clods. These pores hold water and air for absorption by plant roots.
  11. 20. Color difference on a mass of moderately poorly drained soil.
  12. 21. Atmospheric action on rock surfaces producing decomposition, disintegration, or alteration of rocks at or close to the earth’s surface
  13. 23. The horizon of weathered rock or partially weathered soil material from which the soil is formed.
  14. 24. deposition above them.
  15. 26. A size term denoting particles, regardless of mineral composition, with diameter less than 2 microns.
  16. 27. An elongated depression between uplands, hills, or mountains.
  17. 29. Any living individual whether plant or animal.

  1. 2. Process of removing soil from the surface.
  2. 3. The addition of sediment, as by flowing water.
  3. 6. The mineral and organic surface of the earth capable of supporting upland plants. It has been (and is being) formed by the active factors of climate and biosphere exerting their influence on passive parent material and topography over neutral time.
  4. 8. To move or transfer from one place to another; cause to change location; displace.
  5. 9. The removal of soluble constituents from soils or other materials by percolating water.
  6. 10. Slope of the land and the position on the landscape, such as the top of a hill, a hillside, or the foot of a slope.
  7. 12. Soil whose properties are dominated by soil minerals, usually containing less than 20 percent organic matter.
  8. 15. Mineral matter of variable composition, consolidated or unconsolidated, assembled in masses or considerable quantities in nature.
  9. 16. Small, mineral, soil particle, ranging in diameter from 0.5 to 0.002 millimeters.
  10. 18. Decrease in volume of sediments, as a result of compressive stress, usually resulting from
  11. 22. Matter found in, or produced by, living animals and plants, which contains carbon, hydrogen, oxygen,and often nitrogen and sulfur.
  12. 25. Any vegetation that grows close to the ground, producing protection for the soil.
  13. 28. The long-term average weather conditions.
