  1. 7. Unweathered hard rock that lies directly beneath the soil layers or superficial geological deposits, such as glacial drift.
  2. 8. An organism so small that it cannot be seen clearly without the use of a microscope.
  3. 9. Change in form, appearance, nature, or character.
  4. 15. The horizon of weathered rock or partially weathered soil material from which the soil is formed.
  5. 18. Soil whose properties are dominated by soil minerals usually containing less than 20 percent organic matter.
  6. 19. 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.
  7. 21. A size term denoting particles, regardless of mineral composition, with a diameter less than 2 microns.
  8. 23. Designating the inorganic nature of a substance.
  9. 25. 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.
  10. 27. The artificial application of water to soil to increase plant production.
  11. 28. Process of removing soil from the surface.
  12. 29. Accumulation of water-worn pebbles larger than two millimeters in diameter.

  1. 1. Process of soil deposited due to erosion.
  2. 2. The addition of sediment, as by flowing water.
  3. 3. The long-term average weather conditions.
  4. 4. Mineral matter of variable composition, consolidated or unconsolidated, assembled in masses or considerable quantities in nature.
  5. 5. 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.
  6. 6. To move or transfer from one place to another; cause to change location; displace.
  7. 10. A group of textural classes in which the particles are finer than gravel but coarser than silt, ranging in size from 0.5-2.0mm in diameter.
  8. 11. Small, mineral, soil particle, ranging in diameter from 0.002-0.5mm.
  9. 12. Decrease in the volume of sediments due to compressive stress, usually resulting from continued deposition above them.
  10. 13. An elongated, erosional depression usually occupied by a stream with a downward slope conforming to the direction of flow of the occupying stream and includes both bottomland and slopes.
  11. 14. Any vegetation that grows close to the ground, producing protection for the soil.
  12. 16. The removal of soluble constituents from soils or other materials by percolating water.
  13. 17. 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.
  14. 20. Any living individual, whether plant or animal.
  15. 22. Matter found in, or produced by, living animals and plants, which contains carbon, hydrogen, oxygen, and often nitrogen and sulfur.
  16. 24. Atmospheric action on rock surfaces producing decomposition, disintegration, or alteration of rocks at or close to the earth’s surface.
  17. 26. To gather or collect.
