Carbon cycle
Across
- 4. Deep ocean currents driven by temperature and salinity, crucial for long-term carbon storage.
- 5. Achieving net-zero carbon emissions.
- 8. Breakdown of dead organic matter by bacteria/fungi, releasing carbon into the soil and atmosphere.
- 10. Organisms break down carbohydrates, releasing carbon dioxide back into the atmosphere.
- 12. Planting trees to increase carbon storage.
- 13. Rapid, short-term transfer through photosynthesis and respiration.
- 14. The movement or transfer of carbon between stores, measured in petagrams (PgC) or gigatonnes (GtC) per year.
Down
- 1. Long-term storage of carbon in oceans, vegetation, or geological formations. Includes CCS (Carbon Capture and Storage).
- 2. Burning organic material or fossil fuels, releasing carbon.
- 3. Plants remove carbon dioxide from the atmosphere and convert it into carbohydrates.
- 6. Slow, long-term cycle involving rock weathering, burial, and sedimentation over millions of years.
- 7. The ownership and control of energy sources, production, and transport.
- 9. A store that emits more carbon than it absorbs (e.g., burning fossil fuels).
- 11. A store that absorbs more carbon than it emits (e.g., oceans, forests).
