  1. 2. Parent material is the geologic material from which soil horizons form. There are seven variations of parent material. Weathered Bedrock, Till, Outwash Deposit, Eolian Sand, Loess, Alluvium, and Local Overwash. Here are the rules for distinquishing which one to pick on the scorecard.
  2. 3. the process of eroding or being eroded by wind, water, or other natural agents.
  3. 6. a chemical or natural substance added to soil or land to increase its fertility.
  4. 9. The soil texture triangle is one of the tools that soilscientists use to visualize and understand the meaning ofsoil texture names. The textural triangle is a diagram which shows how each of these 12 textures is classified based on the percent of sand, silt, and clay in each.
  5. 10. the state or process of rotting; decay.
