- 6. Radiation: heat energy from the sun
- 7. Energy- Is the energy from the Sun transmitted as electromagnetic wave
- 8. Energy- Stored energy or energy of position
- 9. Most abundant of nonrenewable resource produces sulfur dioxide
- 11. outer layer that creates the ‘solar wind’ which can go 800 km/s
- 13. Cycle- The continuous process by which carbon is exchanged between organisms and the environment
- 14. an electromagnetic wave of high energy and very short wavelength, which is able to pass through many materials opaque to light
- 15. A soft brownish coal showing traces of plant structure, intermediate between bituminous coal and peat
Down
- 1. waves- Electromagnetic radiation spectrum at wavelengths longer than those of visible light
- 2. occurs as pockets of air near earth’s surface are heated, become less dense, rise, cool, and sink
- 3. Winds: They are a continuous stream of electrically charged particles that are given off by a magnetic field around the sun
- 4. cooler areas of surface that appear darker
- 5. Hard variety that contains relatively pure carbon and burns with little flame and smoke (cleanest burning)
- 10. The ability to do work
- 12. Fuels- Fuel that have been formed from the fossilized remains of prehistoric plants and animals
