Across
- 3. is composed of divided rock and mineral particles and is considered to have the largest grain size.
- 5. holds water well due to its very small grain size
- 7. is the action of water falling with gravity.
- 9. is when organic substances are broken down into simpler forms of matter.
- 12. is soil composed of sand, silt, and clay in relatively even concentration (about 40-40-20% concentration).
- 13. is the finely divided organic matter that provides nutrients essential for plant growth, increases soil water absorption, and improves soil workability.
Down
- 1. the movement and filtering of fluids through pores in the soil.
- 2. the rock that breaks down which gives the soil its structure and minerals.
- 4. the plants and animals of a region
- 6. is the loss of plant nutrients from the soil, due to rain.
- 8. the average weather conditions of a particular place or region over a period of years
- 10. is the broken down remains of plants and animals in the environment.
- 11. is a layer parallel to the soil surface, whose physical characteristics differ from the layers above and beneath.
- 14. has a grain size somewhere between sand and clay and is typically deposited at the bottom of a body of water.
