Across
- 1. a jacket of gasses that Earth is surrounded by
- 3. extra greenhouse gasses can cause Earth's atmosphere to trap more and more heat, which can increase the temperature and eventually lead to
- 8. A kind of energy source that takes a very long time to regenerate.
- 10. The process whereby plants make the carbohydrates glucose, sucrose, and starch from sunlight, carbon dioxide and water
Down
- 2. Electromagnetic radiation emitted by the sun.
- 4. The effect of various gasses on our planet, which occurs when gasses in Earth's atmosphere trap the Sun's heat, which makes the Earth much warmer
- 5. rock-like, gas, or liquid resources that are burned to generate power. They include coal, natural gas, and oil, and are used as an energy source in the electricity and transportation sectors.
- 6. The process whereby plants and animals convert carbohydrates, water, and oxygen into energy, carbon dioxide and water are released as byproducts of this process
- 7. a gas that controls the amount of water vapor in the atmosphere and so helps control the size of the greenhouse effect
- 9. A kind of energy source used for making products or for generating power, such as solar and wind
