Down
- 1. A microbially facilitated process where nitrate is reduced and ultimately produces molecular nitrogen through a series of intermediate gaseous nitrogen oxide products.
- 2. The biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of Earth.
- 5. Converts ice directly into water vapor, bypassing the liquid phase.
- 7. Water held underground in the soil or in pores and crevices in rock.
- 9. A process by which water is transformed from liquid to a gaseous state.
- 10. The process through which gaseous water vapor becomes liquid water.
- 11. The element of life.
- 12. The biogeochemical cycle by which nitrogen is converted into multiple chemical forms as it circulates among atmospheric, terrestrial, and marine ecosystems.
- 14. Any liquid or frozen water that forms in the atmosphere and falls back to the earth.
