APES Soil Choice Activity - HA
Across
- 4. The process when water dissolves and carries away nutrients, minerals, and other soluble substances from the soil which can lead to nutrient loss and soil degradation
- 6. Distinct layers of soils that vary in composition, texture, and color that influence plant growth
- 9. Essential elements required by plants and animals for survival and growth
- 12. Fine particles of soil 0.002-0.5 mm in diameter that retain water and nutrients
- 14. Space between soil particles that hold air and water
- 16. Physical features and layout of the land surface, including hills, elevation, and landforms
- 17. Balanced soil mix of sand, silt, and clay
- 19. Consists of weathered "parent material" like bedrock or gravel (foundation for soil development)
- 20. Decomposed plant and animal material in soil including leaf litter, animal remains, and microorganisms
- 23. Layer of dead leaves and organic material that falls to the forest floor
- 24. Small particles of rock and mineral material that are pretty small and can provide good drainage in soil
Down
- 1. Bacteria, fungi, and worms that break down organic material into simpler compounds that recycle nutrients
- 2. Uppermost layer of soil made of organic materials like decomposed plants
- 3. Movement of weathered material from one place to another commonly by way of wind, water, or ice
- 5. Topsoil layer of the soil profiles made of humus and minerals
- 7. Aka subsoil; made up of mineral material leached from topsoil that contains clay, some nutrients, and organic material from the A horizon
- 8. Organic component of soil formed by the decomposition of plants and animals that's rich in nutrients
- 10. How climate, organisms, topography, and time create soil
- 11. Substance of nitrogen, phosphorous, and potassium added to soil to enhance its fertility and support plant growth
- 13. Particles less than 0.002 mm that has high nutrient and water retention but poor drainage
- 15. Geologic material from which soil forms(usually from bedrock/sediment)
- 18. Measure of "void spaces" or pores in soil that indicates the soil's ability to hold air and water
- 21. When rocks and minerals break down into smaller particles due to physical, chemical, or biological forces
- 22. Coarse rock particles often found in lower soil horizons
