The Cycles of Matter
Across
- 2. the process during which water vapor changes into liquid water
- 4. the movement of carbon from the nonliving environment into living things and back
- 6. processes that recycle the earth's limited resources
- 8. the movement of water from the Earth to the atmosphere and back
- 10. water that falls from clouds to Earth's surface
- 11. the process during which liquid water changes into a gas called water vapor
Down
- 1. the burning of fossil fuels which releases carbon into the atmosphere
- 3. evaporation of water from the leaves of a plant
- 5. the movement of oxygen from the nonliving environment into living things and back
- 7. returns carbon to the soil and releases carbon into the atmosphere
- 9. natural energy sources—like coal, oil, and natural gas—formed deep underground from the buried remains of plants and animals that lived millions of years ago
