Across
- 4. an electromagnetic wave of high energy and very short wavelength, which is able to pass through many materials opaque to light.
- 5. The source of all energy on Earth
- 6. Rays Invisible rays that are part of the energy that comes from the sun. Filtered by ozone layer
- 10. Flares explosive out burst
- 12. Partially decayed plant material, burns dirty lots of pollution
- 15. Radiation heat energy from the sun
- 16. occurs when heat energy is transferred from earth’s surface air to atmospheric air.
- 18. Energy Is the energy from the Sun transmitted as electromagnetic wave.
- 20. Most abundant of nonrenewable resource produces sulfur dioxide
- 22. Is a relatively soft coal containing a tarlike substance called bitumen. It is of higher quality than lignite coal but of poorer quality than anthracite
- 24. Resource Is a natural resource that cannot be re-made or re-grown at a scale comparable to its consumption.
- 26. The ability to do work
- 27. Fuels Fuel that have been formed from the fossilized remains of prehistoric plants and animals.
Down
- 1. Rays electromagnetic radiation with wavelengths shorter than approximately one tenth of a nanometer. Fastest
- 2. waves Electromagnetic radiation spectrum at wavelengths longer than those of visible light,
- 3. cooler areas of surface that appear darker
- 7. Energy Energy of motion
- 8. outer layer that creates the ‘solar wind’ which can go 800 km/s
- 9. Energy Stored energy or energy of position
- 11. surface layer responsible for most of visible light
- 13. Cycle The continuous process by which carbon is exchanged between organisms and the environment.
- 14. Rain Rain that has a lower than normal pH level because of burning fossil fuels
- 17. Waves Have the longest wavelengths in the electromagnetic spectrum, slowest
- 19. Winds They are a continuous stream of electrically charged particles that are given off by a magnetic field around the sun.
- 21. occurs as pockets of air near earth’s surface are heated, become less dense, rise, cool, and sink.
- 23. Transform Energy’s ability to change from one form to another
- 25. of Conservation of Energy States that energy can change form, but it cannot be created or destroyed.
- 28. A soft brownish coal showing traces of plant structure, intermediate between bituminous coal and peat.
