Across
- 1. a natural resource that cannot be re-made or re-grown at a scale comparable to its consumption.
- 5. Rain Rain that has a lower-than-average pH level because of burning fossil fuels
- 7. the slowest; have the longest wavelengths in the electromagnetic spectrum
- 9. heat energy created by the sun
- 10. Flares an explosive out burst
- 11. soft brownish coal that has traces of plant structure, intermediate between bituminous coal and peat.
- 12. the fastest; electromagnetic radiation that has wavelengths less than one tenth of a nanometer.
- 15. an electromagnetic wave of lots of energy and short wavelength, it is able to pass through many materials opaque to light.
- 16. happens when heat energy is moved from earth’s surface air to atmospheric air.
- 17. energy that is stored or energy of position
- 18. waves Electromagnetic radiation spectrum the wavelengths are longer than those of visible light.
- 21. layer of earth responsible for most of visible light
- 22. contains relatively pure carbon and burns with little flame and smoke (cleanest burning)
- 23. the Energy of motion
- 26. the ability to complete work
- 27. the invisible rays that are of the energy that comes from the sun
- 28. main source of energy on Earth
- 29. softer coal contains a tarlike substance called bitumen. It is of higher quality than lignite coal but of poorer quality than anthracite.
- 30. process where carbon is exchanged between organisms and the environment.
Down
- 2. when pockets of air near earth’s surface are heated, become less dense, rise, cool, and sink.
- 3. colder areas of earth's surface that appear darker
- 4. are a continuous stream of electrically charged particles that are given off by a magnetic field around the sun.
- 6. states that energy changes form, but it cannot be created or destroyed.
- 8. outer layer of earth that creates the ‘solar wind
- 13. the energy’s ability to change from one form to another
- 14. the energy from the Sun transmitted as electromagnetic waves.
- 16. Most abundant nonrenewable resource
- 19. Fuel is created from the fossilized remains of prehistoric plants and animals.
- 20. a type of nonrenewable resource that is drilled out of the ground used for gasoline
- 24. use of organic waste through natural decomposition
- 25. Mostly decayed plant material creates lots of pollution
