- 3. Fossil fuels are fuels like oil, coal, and gas that are nonrenewable sources
- 4. Ozone depletion is the depletion of the ozone layer that is saving us from the sun’s rays
- 6. Nonrenewable energy is energy where the energy can not be used again
- 8. These are sources of energy that will never run out and are renewable sources of energy
- 11. Reusing and recycling of energy to make sure it is not wasted
- 14. To take away or take a part of
- 15. turbines to create kinetic energy
- 16. The greenhouse effect is where the earths eats the sun’s rays and sends it back out as infrared rays
- 18. The pollution coming from mechanical vehicles using fossil fuels
- 21. This is where the kinetic energy of the wind can be used as mechanical or electrical energy
- 23. Global warming is when the earth is heating up because of our use of nonrenewable resources
- 24. Renewable energy is energy that can be used multiple times instead of just burning off
Down
- 1. Climate change is a factor of global warming which is that the temperature heats up
- 2. something that there is few of or not many
- 5. This is energy collect from water
- 7. any plant material or wastes. or The amount of dried living matter in a square meter
- 9. These are cells that use the sun’s rays and convert them into electrical currents
- 10. This is thermal energy obtained from
- 12. Heat obtained from the sun’s heat and light
- 13. heat inside the earth's crust
- 17. This happen when the nucleus of atoms are split and the heat created is used
- 19. To slowly go away
- 20. will be there forever and you can not deplete it
- 22. Wind turbines are large structures that when moved by the wind create energy
