Across
  1. 5. / Very loose soil made of the largest particles, like pebbles.
  2. 6. / The second, or middle layer of soil, light colored. It's a mixture of clay, sand, and silt.
  3. 8. / A soil that is a mixture of sand, silt, and clay. This soil feels crumbly and holds some water but not too much. Most plants grow best in this type of soil.
  4. 9. / When all the spaces in the soil are filled with water, and the soil can't hold anymore water.
  5. 10. / The process of rocks being broken down into smaller pieces by plant roots breaking through the rocks or water freezing in spaces and expanding/crumbling the rock.
  6. 12. / Mixture of rock pieces, plants and animal remains, water and air.
  7. 13. / The dropping or settling of eroded materials.
  8. 15. / Gritty, loose soil made mostly of large particles of sediment. (It's large spaces between the particles allow water to pass through easily, therefore it does not retain water well.)
  9. 17. / Silky smooth soil made of small particles from flooded river sediment.
  10. 19. The third layer of solid rock. (It's the un-weathered layer of rock.)
Down
  1. 1. / Decayed plants and animal remains which provide nutrients to growing plants. (It's dark brown or black in color.)
  2. 2. / Heavy, sticky soil made mostly of the smallest particles. (It's smooth, it has the smallest particles, and it retains (holds) the most water).
  3. 3. / What the surface or body of the soil looks like or feels like. (The color and feel of soil.)
  4. 4. / A layer of soil with different physical characteristics from the layer of soil above it an the layer of soil below it.
  5. 6. / Topsoil, Subsoil, & Bedrock
  6. 7. / This is where soil is formed from weathered rock. (Over time rocks breakdown into tiny pieces or particles.)
  7. 11. / The top layer of soil, that is dark and rich in humus. (This thin, top layer is rich in organic matter : (humus) which allow plants to grow well.)
  8. 14. / Sand, bits of rock, fossils, and other matter carried and deposited by water, wind or ice.
  9. 16. / The process of moving weathered rock and sediment from one place to another.
  10. 18. / To hold with in, as soil does with water. (Soil holding in water.)
