  1. 2. A carbon sink that cover’s a large amount of the earth’s surface, with some of the carbon being stored in the shells of crustaceans.
  2. 4. Carbon ________, the repeating process of carbon changing forms and moving around earth’s spheres
  3. 9. Source of energy from outside earth’s spheres that enables photosynthesis.
  4. 11. A product of photosynthesis and essential gas for sustaining life
  5. 13. Climate _______ change can result if the greenhouse effect is too strong, trapping more heat in the atmosphere.
  6. 15. Water________, a greenhouse gas that is also critical part of the water cycle, leading to the formation of clouds.
  7. 16. Nitrous _______ , a greenhouse gas containing nitrogen and oxygen. Also a useful painkiller
  8. 17. Carbon _________, a greenhouse gas containing carbon and oxygen
  9. 18. A greenhouse gas containing carbon and hydrogen
  10. 20. The __________ effect is the mode by which energy from the sun is trapped inside earth’s atmosphere.
  11. 21. Plants with high amounts of green leaves that are necessary for photosynthesis which reduces carbon dioxide in our atmosphere

  1. 1. A product of photosynthesis containing carbon, hydrogen and oxygen that is the basis of all foods
  2. 3. The process by which living organisms consume carbohydrates for energy and release carbon dioxide
  3. 4. The specific set of conditions (temperature, seasons, humidity, rainfall etc) that enable certain plants and animals to survive in a local area.
  4. 5. A fossil fuel that is typically black or brown and sometimes used in the production of electricity
  5. 6. A carbon ______ is a substance that stores carbon on earth
  6. 7. The process by which plants turn carbon dioxide, water and sunlight into sugars and oxygen
  7. 8. The process of burning fossil fuels in the presence of oxygen to release energy and carbon dioxide
  8. 10. Alternate sources of energy (solar, wind, tidal) that do not rely on the combustion of carbon based fuels. About 50% of WA’s electricity
  9. 12. A fossil fuel that is typically used in car engines
  10. 14. _______ fuels contain carbon which when combusted release energy and carbon dioxide
  11. 19. A fossil fuel that is typically used in heavy vehicles - trucks, buses, farming equipment etc
